Some of the new things this season:
For more information about the 2019-2020 influenza vaccine recommendations:
What is the recommended flu vaccine this season ?
for the 2019-2020 flu season, the provider can choose to manage each licensed flu vaccines according to age (IIV, RIV4, or LAIV4)
This season Options include .:
There are shows all FDA-approved flu vaccine for use in the United States during the 2019-2020 season.
What will the 2019-2020 virus flu vaccine protect against?
There are many different flu viruses and they are constantly changing. US flu vaccine composition is reviewed annually and updated as needed to match the circulating flu viruses. flu vaccine protects against three or four viruses (depending on the vaccine) that research indicates will be most common. For 2019-2020, trivalent (three component) vaccine is recommended to contain:
quadrivalent (four component) vaccine, which protects against the two virus B lineage, it is recommended to contain:
FDA vaccines and Related Biological Products Advisory Committee (VRBPAC) choose virus flu vaccine for the United States. For the 2019-2020 vaccine, the H3N2 component Elections postponed until March 22, 2019.
How suitable is the 2019-2020 vaccine for the virus circulating flu virus? How well the flu vaccine to protect against disease?
It’s understandable that people want to know how well the flu vaccine works or expected to work this season. The CDC does not have an estimate for this season yet because it is still early in the season and these estimates are based on epidemiological studies that compare disease among the vaccinated than the unvaccinated. The data will be available later.
Meanwhile, laboratory data can provide some insight into how well the vaccine might work. The data are most helpful for antigen characterization data, which is updated every week. Data antigenic limited to viruses circulating recently available at this point in the season, and the data showed similarities circulating influenza A (H1N1) virus pdm09 and B / Yamagata viruses tested so far for the vaccine. However, influenza B / Victoria and A (H3N2) viruses tested showed some similarity decreases with the vaccine virus. Again, at this point in the flu season, the data antigenic limited and can provide early insight into how well the vaccine might work. For more information about how CDC flu virus antigen characteristic is, and a more complete antigenic Data will be available in the coming weeks.
During the last season when the virus antigenic vaccine “as” most of the circulating virus, the effectiveness of the vaccine in the range of 40% to 60% have been observed. This means that people who get vaccinated may still sick, but they are about half as likely to get sick as someone who was not vaccinated. One important thing to remember is that vaccination can make the disease less severe in people who get vaccinated and still in pain. In general, people who get vaccinated are better than those who do not get vaccinated. It’s important to remember though, that things can change very quickly with the flu and we could still see a significant circulation of influenza viruses with this season.
For further information on the effectiveness of the flu vaccine available.
Because of the time of onset, peak and end of flu season varies from year to year and can not be predicted, it is difficult to say when the best time to be vaccinated for a season. In trying to balance the need to get as many people vaccinated before flu activity starts with concerns about potentially waning vaccine-induced immunity during flu season, CDC and ACIP recommends that vaccination will be offered at the end of October.
Children 6 months to 8 years who require 2 doses should receive their first dose as soon as possible after the vaccine became available to allow the second dose (which must be given at least 4 weeks later) to be received at the end of October < / p>
for people who only need one dose for this season, the initial vaccination -. For example, in July or August -may lead to reduced protection against the flu later in the season, especially among older adults. While vaccination should optimally occur before the onset of influenza activity in the community, providers must continue to offer and encourage vaccination during the flu viruscirculating and vaccine is not over yet available. To avoid loss of opportunity for vaccination, vaccination can be offered during routine health care visits and hospitalized.
Can I get the flu vaccine if I’m allergic to eggs?
for people with egg allergies are not changed and as follows 😕
Why is it important that the vaccine virus cells grown used to produce a flu vaccine
virus vaccine adult cells do not have any changes that may be present in the virus reference egg-adult, so they should be similar to the circulating “wild-type” virus. the vaccine’s effectiveness depends in part on the match between the flu vaccine and circulating virus.
Is the flu vaccine made using cell-grown vaccine virus and cell-based technology is more effective than vaccines made using egg-grown vaccine virus and egg-based technology?
While the use of the vaccine virus cell-growth and technology-based cells may offer the potential for better protection on, a flu vaccine based on the traditional egg because they produce a viral vaccine that is more similar to the flu virus in circulation, there is no data the effectiveness of the vaccine for this support. There is no preferential recommendation for one flu vaccine over the other.
What kind of flu season is expected this year?
Influenza is unpredictable. While spreading the flu every year, time, severity, and length of the season varies from one season to another.
Will the new flu virus circulating this season?
Flu viruses are constantly changing so it is not unusual for new flu viruses emerge every year. More information on available.
Would the United States have the flu?
United States undergo an annual epidemic of seasonal flu. This time of year is called “flu season.” In the United States, the most common flu virus during the autumn and winter. frequent flu activity began to increase in October and November. Most of the time influenza activity peaks between December and February, and could last until the end of May. CDC monitors certain key flu indicators (eg, outpatient visits influenza-like illness (ILI), laboratory test results and reports from the hospital flu and deaths). When these indicators are rising and remain elevated for several weeks in a row, “flu season” is said to have begun. increased ILI usually first, followed by an increase in flu-related hospitalizations, followed by an increase in flu-related deaths
For the latest influenza surveillance information: ..
when flu activity will begin and when will it peak?
when flu is unpredictable and can vary in different parts of the country and from season to season. seasonal flu virus can be detected throughout the year; However, seasonal flu activity often begins in early October and November and may continue to occur until the end of May. flu activity most often peaks in the United States between December and February.
What should I do to protect yourself from the flu this season?
The CDC recommends annual for all people ages 6 months and older as the first and most important step in protecting against this serious disease.
In addition to getting the seasonal flu vaccine, you can take such as staying away from sick people and washing hands to reduce the spread of germs. If you are sick with the flu, stay home from work or school to prevent the spread of flu to others. In addition, there is a prescription drug called that can be used to treat flu illness.
What should I do to protect my loved ones from the flu this season?
Encourage your loved ones to get vaccinated. Vaccinations are very important for people with high risk of developing influenza and their close contacts. Also, if you have a loved one at high risk of developing flu complications and they get flu symptoms, prompting them to seek medical attention for possible treatment with influenza antiviral drugs. These drugs work best if given within 48 hours of when symptoms begin. CDC recommends that people who are at high risk for serious flu complications and who get flu-like symptoms during the flu season flu is treated with antiviral drugs as soon as possible without waiting for confirmatory testing. People who are not at high risk for serious flu complications can also be treated with influenza antiviral medications, especially if treatment can be started within 48 hours.
Are some children require two dosesflu vaccine?
As in the previous season, will need two doses of flu vaccine this season. Children in this age group who had not previously received two or more the number of doses of trivalent vaccine or quadrivalent influenza (including the nasal spray vaccine) before July 1, 2019, or whose vaccination history is unknown, need two doses of flu vaccine from 2019 to 2020 is given at least 4 weeks ,
For an 8-year-olds who need two doses, the second dose is recommended even if the child turns 9 years between the receipt of dose 1 and dose 2 children in this age group who had received two or more the number of doses trivalent or quadrivalent flu vaccine before July 1st 2019 needs only one dose for this season.
What can I do to protect children who are too young to get vaccinated?
Children younger than 6 months are at high risk of serious flu complications, but are too young to get a flu vaccine. Therefore, keeping them from getting the flu is very important. If you live with or care for infants younger than 6 months, you should get a flu shot to help protect them from the flu. available for further information. All the people who are around infants should also be vaccinated. Also, studies have shown that flu vaccination of the mother during pregnancy to protect the baby after birth of flu infection for several months.
In addition to getting vaccinated, you and your loved ones can take as staying away from sick people and washing hands to reduce the spread of germs. If you are sick with the flu, stay home from work or school to prevent the spread of flu to others.
How many flu vaccine will be available this season?
Flu vaccines are produced by private producers, so the supply depending on the manufacturer. For the 2019-2020 season, manufacturers have projected they will provide as much as 162 million to 169 million doses of flu vaccine, which is similar to the projected supply to last season. update flu vaccine supplies will be provided when available.
Is one available flu vaccine is recommended over the other?
For the 2019-2020 influenza season, ACIP recommends yearly. flu vaccination for everyone 6 months and older with a licensed, flu vaccines according to age (IIV, RIV4, or LAIV4) without the expressed preference for any one vaccine over the other
No to choose from; The most important thing is for everyone 6 months and older to get a flu shot every year. If you have questions about which vaccine is best for you, talk to your doctor or other health care professional.
Why is the nasal spray is recommended as an option this year when it has proven ineffective in the past flu season?
flu vaccine effectiveness (VE) can vary from year to year, between age and the risk of different groups, the type of vaccine, and even by virus types and subtypes. While the data from 2010-2011 through 2016-2017 showed that the nasal spray vaccine is not as effective for between 2 and 17-year-olds against the H1N1 virus in the US, the nasal spray vaccine is effective against influenza B virus, and is equally effective against the H3N2 virus as a vaccine influenza inactive. Since the 2018-2019 season, the nasal spray vaccine manufacturers have been using the new H1N1 vaccine virus production. Some data indicate this will lead to increased effectiveness against H1N1. However, there are no published estimates of effectiveness for this vaccine component against the H1N1 virus is available. ACIP and CDC as to continue on the use of the nasal spray vaccine is based on evidence that the new H1N1 component will result in an increase in the effectiveness of a vaccine against this virus. There is no express a preference for any flu shot or nasal spray vaccine.
Where can I get the flu vaccine?
Flu vaccines are offered by many doctors offices, clinics, health departments, pharmacies and college health centers, as well as by many businessmen, and even by some schools.
Even if you do not have a regular doctor or nurse, you can get the flu vaccine in other places, such as health departments, pharmacy, urgent care clinics, and often school, college health centers, or work.
helps you to find where you can get the flu vaccine.
What is the flu vaccination using jet injectors?
The FDA has approved a flu vaccine (Afluria quadrivalent) for administration by jet injector device (which PharmaJet Stratis 0.5ml needle-free jet injector) for the 18 through 64 years. It’s only two flu vaccine is approved for administration by jet injector. People aged 18 to 64 years old can receive the vaccine either by jet injector or a needle. A jet injector is a medical device used for vaccination using a high pressure, a narrow stream of fluid through the skin instead of a syringe. More information on available.
What adjuvanted flu vaccine?
The FDA licensed seasonal flu vaccine containing adjuvant for adults 65 years and older. Adjuvant is a substance added to vaccines to make a stronger immune response to vaccination. was licensed in November 2015 and will be available during the 2019-2020 flu season. It includes the adjuvant MF59, an oil-in-water emulsion containing squalene oil. FLUAD ™ is marketed in the United States.
Can I get vaccinated and still get the flu?
Yes. It is possible to get sick with the flu even if you have been vaccinated (though you would not know for sure unless you get a flu test). It is possible for the following reasons 😕
How effective flu vaccine will be this season
It is not possible to say in advance exactly how well the flu vaccine will work this season. How well it works can vary by season, virus type / subtype, type of vaccine, and the age and other host factors than people who are vaccinated. At least two factors play an important role in determining the likelihood that the flu vaccine will protect against the flu: 1) the characteristics of people who are vaccinated (such as their age and health), and 2) the similarity or “match” between the flu virus in the vaccine and they spread in society.
During the years when the viruses in the flu vaccine and circulating influenza viruses are well matched, it is possible to measure the huge benefits of influenza vaccination in preventing the flu. However, even during the years when the vaccine is a good match, the benefits of flu vaccination will vary across the population, depending on host factors such as the health and age of the vaccinated person and even potentially the flu vaccine used.
The latest study by researchers at the CDC and other researchers show that flu vaccination typically reduce the risk of influenza illness by 40% to 60% among the population as a whole when the vaccine virus as it spreads in the community.
For more information about the effectiveness of the vaccine,
flu vaccine this season will be a good match for circulating viruses?
This is not possible to predict with certainty if the flu vaccine would be suitable for circulating flu viruses. The flu vaccine is made to protect against the flu virus research and surveillance show will likely be the most common during the season. However, scientists have to choose which of the flu virus in a flu vaccine many months in advance so that the flu vaccine to be produced and delivered on time. Flu viruses change constantly (called “drift”). They can change from one season to the next or they can even change within one flu season. Another factor that may influence the effectiveness of vaccines, particularly against influenza A (H3N2) virus, the changes that can occur in virus vaccines because they grow in eggs, which is. Due to these factors, there is always the possibility of less than optimal match between circulating viruses and the flu virus in the flu vaccine.
During the flu season, the CDC study circulating flu virus samples to evaluate how close a match exists between the virus used to make the flu vaccine and flu viruses in circulation.
One way to help the CDC to evaluate the match between circulating viruses and the flu vaccine is a flu virus with lab process called ‘genetic and’. Results of genetic and antigenic characterization testing at the CDC published weekly.
Can the flu vaccine provides protection even if the flu vaccine is not “good” game?
Yes, the antibodies made in response to vaccination with the flu virus sometimes can provide protection against different flu viruses but related. A less than ideal match may result in reduced effectiveness of the vaccine against the flu virus that is different from what is in the flu vaccine, but may still provide protection against the flu.
In addition, it is important to remember that the flu vaccine contains three influenza virus or four (depending on the type of vaccine you received) so that even when there are less than ideal match or lower effectiveness against the virus, the flu vaccine can protect against other flu viruses.
For this reason, even during the season when there are less than ideal match, CDC continues to recommend influenza vaccination for everyone 6 months and older. Vaccinations are very important for, and their close contacts.
What happens in the body when a person has the flu?
The flu virus usually infects the respiratory tract (ie, the air passages of the nose, throat and lungs). As the progress of the infection, the immune system responds to fight the virus. It produces inflammation that can trigger respiratory symptoms such as cough and sore throat. The response of the immune system can also trigger fever and cause muscle or body aches. When an infected person coughs, sneezes, or speaks, they can spread the flu virus in respiratory droplets for people who are nearby. People may also get flu by touching a contaminated surface or object that has flu virus on it and then touching their own mouth or nose.
Most people who become sick will recover within a few days to less than two weeks, but some people may be more severe pain. After a flu infection, moderate complications such as ear and sinus infections can occur secondary. Pneumonia is a serious flu complications that can result from either influenza virus infection itself or from co-infection with flu viruses and bacteria. Another serious complication that may be triggered by the flu can include inflammation of the heart (myocarditis), the brain (encephalitis) or muscles (myositis, rhabdomyolysis) networks, and multi-organ failure (eg, respiratory and renal failure). severe complications can occur in anyone, but may be more likely to occur in people who have certain chronic medical conditions, or in the elderly.
What should I do if I had the flu?
Most people with flu have a mild illness and did not require medical care or antiviral drugs. If you are sick with flu symptoms, in most cases, you should stay home and avoid contact with other people except to get medical care.
However, if you have flu symptoms and are at high risk of flu complications, or very ill or worried about your illness, call your health care provider. There are drugs your doctor may prescribe to treat flu antiviral called. These drugs can make you better faster and may also prevent serious complications.
The antiviral drugs are prescription drugs that can be used to treat flu illness. People in the flu seriously recommended for antiviral treatment is fast, including children younger than 2 years (although all children younger than 5 years old are considered at high risk for complications from the flu, the highest risk is for those younger than 2 years) , adults age 65 and older, pregnant women, people with certain long-term medical conditions and residents of nursing homes and other long-term care facilities). antiviral treatment as early as possible is also recommended for people who are very sick with the flu (such as those with a complex, progressive disease or people hospitalized because of the flu). Others can be treated with antivirals at their discretion health care professional. Treat people at high risk or those who are very sick with the flu with antiviral medications is very important. Studies show that prompt treatment with antiviral drugs can prevent serious flu complications. appropriate treatment can mean the difference between having a milder illness than a very serious disease that can result in a hospital stay.
Treatment with antiviral is best when started within 48 hours of illness. However, the treatment may still be useful if given later in the disease course. Antiviral drugs are effective in all age groups and risk. Studies show that the antiviral drugs are under-prescribed for people at high risk of complications who get the flu. Four FDA-approved antiviral drugs are recommended for use during the 2019-2020 flu season: oseltamivir (available in generic versions under the trade name Tamiflu), zanamivir (Relenza®), peramivir (Rapivab®), and baloxavir marboxil (Xofluza ®). Further information about antiviral drugs can be found. These guidelines are consistent with the 2019-2020 flu season were published by the Infectious Diseases Society of America (IDSA) on December 19, 2018, in the journal Clinical Infectious Diseases.
What is baloxavir marboxil?
Baloxavir marboxil (Xofluza® trade name) is a single dose of influenza antiviral drugs approved by the FDA October 24, 2018. Baloxavir approved for the treatment of acute uncomplicated influenza in people 12 years and older who have flu symptoms for less than 48 hours. In randomized clinical trials, baloxavir similar to oseltamivir, flu antiviral drugs currently recommended, in reducing the symptoms of flu
For further information on baloxavir available: ..
What CDC tracks flu activity?
Epidemiology and Prevention Branch in the Influenza Division at CDC collects, compiles and analyzes information about influenza activity throughout the year in the United States and produces FluView report influenza surveillance weekly, and FluView Interactive, which allows for a deeper exploration of data influenza surveillance. US influenza surveillance system is a collaborative effort between the CDC and many partners in state, local, and territorial health departments, public health and clinical laboratories, vital statistics offices, health care providers, clinics, and emergency departments. Information in five categories were collected from eight different data sources which allows the CDC to:

What would the CDC doing to the effectiveness of the flu vaccine monitors in 2019 . -2020 season?
The CDC is working with partners every season to judge how well the seasonal flu vaccine works. During the 2019-2020 season, the CDC is planning several studies about. The researchers conducted this study every year to measure how well the flu vaccine works in order to continually assess and confirm their value as a public health measure.
Part of the need for continued assessment of this is that the flu viruses circulating each year tends to change and evolve, so the flu vaccine components change relatively frequently to protect against viruses that circulate new. Summary of the latest CDC estimates the vaccine efficacy is available at.
What is CDC doing to monitor antiviral resistance in the United States during the 2019-2020 season?
means that the virus has changed so much that the antiviral drug less effective or not effective at all in treating or preventing a disease with the virus. CDC will continue to collect and monitor the flu virus changes through an established network of domestic and global surveillance system. CDC is also working with the state Department of Public Health and the World Health Organization to collect additional information on antiviral resistance in the United States and around the world. The information collected will assist in making recommendations regarding the use of information antiviral drugs to treat influenza.
How to CDC estimates the burden of seasonal flu in the US?
The British state can vary from season to season and is determined by a number of factors including the characteristics of circulating viruses, time of season, the virus circulating immune population, how well the flu vaccine works, and how many people have gotten vaccinated. While the impact of the flu varies, put a large strain on the health of people in the United States each year.
The CDC uses a model to estimate the number of flu, medical visits, and hospitalizations in the United States (as well as the impact of influenza vaccination on these figures). The same model is also extended to estimate flu-related deaths in the United States. This methodology has been used to calculate the flu burden downs, including death ,.
Beginning with the 2018-2019 flu season, the CDC began reporting cumulative load estimate flu season. It will be granted if the activity was sufficient to produce a stable forecast, and will be updated every week during the flu season.
How CDC classifies the severity of the flu season?
in 2017, the CDC adopted and elaborated a new methodology to determine. Based on data from the past flu season, CDC researchers used data key flu indicators to develop a threshold intensity (ITs) to classify the severity of the flu season.
Based on the threshold of intensity, CDC researchers classified the severity of seasonally from 2003 -2004 through the 2018-2019 flu season. Overall, the four seasons are classified as low severity, eight as a moderate, three high, and there are very high.
What is forecasting a cold?
Flu puts the US population each year, but the magnitude and timing vary from seasonseason, making the annual impact is difficult to predict at the beginning of each season. can help predict when beginning, peak, and an increase in flu activity will occur. Unlike the activities of CDC Traditionally, flu size after it has occurred, forecasting flu offers the possibility to look into the future and plan a better future, potentially reducing the impact of the flu and could potentially be used to prepare and prevent illness, hospital, and mortality, and economic burden, experienced during a flu epidemic. When estimate accurately predict flu activity, the ability to more effectively plan the public health response to the epidemic of seasonal flu and influenza pandemic in the future is possible.
Flu forecasting aims to predict the characteristics of the influenza season before going on disease activity and was arrested by the US influenza surveillance systems. Since the 2013-2014 flu season, the CDC’s Influenza Division has been working with the CDC Epidemic Prediction Initiative (EPI) and external research to improve knowledge and use of forecasting flu with flu coordinate forecasting challenges. More recently, it has expanded to challenge the state-level prediction and forecasting hospitalization rate.
During 2018-2019, the CDC began summarizes and posts public flu estimates. For the 2019-2020 flu season, the CDC will continue to display the weekly forecast received by EPI.
