Why You May Still Get Sick After a Flu Shot
Why You May Still Get Sick After a Flu Shot

Flu shots are recommended for everyone ages 6 months and older.

seasonal flu shot is given an annual vaccine to protect against the flu, or influenza.

The United States, the flu shot is recommended for everyone ages 6 months and older ,.

flu can be very serious illness, especially in children, adults age 65 and over, people with underlying health conditions, and pregnant women.

flu vaccination is the best way to protect yourself and your family from the flu, the CDC said.

The strains of flu viruses are constantly changing, so the newly created each year. Scientists made the vaccine before the flu season starts to predict which strains of flu tends to be most common during the upcoming season.

“Since the flu virus is often hovering in the genetic composition, you have to formulate the vaccine, and this is one of the reasons that people have to [get a flu shot] on an annual basis,” said Dr. William Schaffner, medicine and infectious disease experts prevention at Vanderbilt University School of Medicine. flu protects against three or four strains of flu virus. trivalent flu vaccine protects against two strains of influenza A – H1N1 and H3N2 – and one influenza B strain. quadrivalent flu vaccine – offered for the first time in the 2013-2014 flu season -. protects against the same strains as the trivalent vaccine, and influenza B extra pressure

In addition to the standard dose of influenza vaccine delivered by needle, the flu shot is available in several different forms. These include high-dose version for those aged 65 and older; “Cell-based” version which grow in animal cells rather than chicken eggs and is approved for people ages 4 and older; a “recombinant” vaccine that does not use the influenza virus or a full chicken eggs in the production process and is approved for people ages 18 and older; and a nasal spray, which is approved for healthy people ages 2 to 49, but not for pregnant women.

There is also a needle-free flu vaccine, delivered by the so-called jet injectors, which use high-pressure stream of fluid to inject the vaccine, the CDC said. It is approved for adults ages 18 to 64.

The composition of the 2019-2020 flu vaccine will be slightly different from the flu shot last season. In particular, there will be a different strain of the H1N1 virus and a different strain of the H2N3 virus in a flu shot this season, compared to shots last season. , 2019-2020 trivalent flu vaccine will contain the following strains of flu viruses:

2019-2020 quadrivalent vaccine will also contain a second influenza B strain called “B / Phuket / 3073/2013-like (Yamagata lineage ) virus, “which is also included in the quadrivalent vaccine last season.

This year, the World Health Organization in choosing components hold H3N2 flu vaccine for about a month longer than usual, which means that the agency is conducting the selection in March instead of February ,. Delays give health officials more time to Montior circulating H3N2 virus – the rapid change at the time -. and choose the one that best for vaccine

However, as a result, the delivery may be delayed a couple of flu vaccine this year. In July, the pharmaceutical company Sanofi Pasteur, which manufactures flu vaccine in most of the country, said that the delivery of flu vaccine will be delayed by three or four weeks, according to.

“Sanofi Pasteur fully expecting to produce and deliver each dose is provided by our customers, starting with the partial delivery to all customers at the end of August or September, with all deliveries completed by the end of November,” the company wrote in a letter to customers, according to the AAP

flu vaccine companies -. which include quadrivalent Fluzone, Fluzone High-dose and Flublok quadrivalent -. make up about 40% of the US flu vaccine market, or nearly 70 million doses,

CDC again recommends spray during the 2019-2020 flu season, after not recommend a nasal spray in some previous seasons.

As of February 8th, there were already about 26 million illnesses, 250,000 hospitalizations and 14,000 deaths from flu ,.

2019-2020 flu season has been a bit unusual. At the beginning of the season, the main strain circulating flu viruses are influenza type called B. Typically, influenza B does not cause as many cases of influenza A strain (H1N1 and H3N2) and tend to appear later in the flu season, not at the beginning. Indeed, the last time the influenza B and influenza activity in the US dominate during the 1992-1993 flu season ,.

However, in recent weeks, there have been increasing cases of flu caused by H1N1, suggesting the “second wave” of influenza activity due to influenza A.

Just as flu season begins and ends can not be predicted, so that health officials recommend that people get their flu shot at the beginning of autumn, preferably in late October, the CDC said. flu activity usually peaks in January or February.

“We want to get as many people protected against influenza before the influenza become active in communities across the country,” said Schaffner.

Most flu vaccine given before Thanksgiving, Schaffner said, but people can still get their shots throughout the winter. flu vaccination every season will end in June of that year, but Schaffner said that he would consider “too late” to get the flu vaccine after March, unless one is traveling to the southern hemisphere (where the flu season will start).

After vaccination, it takes a person about two weeks to build immunity against the flu.

people can visit to locate a flu shot, even though they had to call the location ahead of time to see if they have the vaccine in stock.

seasonal flu vaccine effectiveness depends on several factors, including how well the strain of flu in the vaccine according to the strain in circulation. Some studies show that when these strains in the vaccine matches the circulating people, individuals who were vaccinated were 60 percent more likely to catch the flu than people who are not vaccinated ,.

the effectiveness of the flu vaccine may also vary depending on the person being vaccinated – vaccines tend to work best in healthy adults and children, and less well on adults older

for example, found that this year’s flu vaccine is not very. effective in adults aged 65 and over. older people who got the vaccine just as likely to visit the doctor for flu-like symptoms they are not getting the vaccine

But other studies show that people who do get sick less functional develop symptoms if they were vaccinated. A finding that the person who got the flu shot were less likely to be hospitalized with the flu.

There are some studies that show high doses of flu vaccine provides better protection for older adults. High-dose flu vaccine contains four times the standard dose of the vaccine, Schaffner said. A study in the New England Journal of Medicine in 2014 found that high-dose vaccine provides 24 percent more protection against flu than the standard dose, said Schaffner.

Yes. Studies show the flu vaccine is safe for women at any stage of pregnancy, the CDC said.

There are several reasons why it is important to, Schaffner said.

“I was pregnant when they get influenza, have a tendency to get a more severe illness,” and are at increased risk of complications and hospitalization from the disease, said Schaffner.

In addition, influenza vaccination in pregnancy helps protect against the flu during the first six months of life, when babies are too young to receive flu vaccinations, said Schaffner. Mother ‘pass protection on a newborn baby, “said Schaffner.

According to the CDC, mild side effects from the flu shot include soreness, redness or swelling at the injection site, mild fever and pain. Only about 1 percent to 2 percent of people who get the flu shot will have a fever as a side effect, says Schaffner.

Rare but serious side effects may occur, including allergic reactions. Symptoms of serious side effects including difficulty breathing, swelling around the eyes or lips, hives, racing heart, dizziness and fever. If you experience any serious side effects, you should immediately seek medical treatment, the CDC said.

For the children, the side effects of the nasal spray flu can include runny nose, wheezing, headache, vomiting, muscle pain and fever. For adults, side effects include runny nose, headache, sore throat and cough. These side effects last shorter than the actual flu, the CDC said.

“It’s a myth that you can get the flu from the flu vaccine,” Schaffner said.

viruses in the flu shot were killed, so people can not get the flu from the flu vaccine. However, because it takes about two weeks topeople to build immunity after they get the flu vaccine, some people may get the flu shortly after they were vaccinated, if they catch the flu during this period.

Some people may also mistakenly attribute symptoms of a cold for a vaccine, Schaffner said.

nasal spray vaccine contains the “live attenuated” flu virus, but the virus is weakened so it can not cause flu. The virus in the nasal spray can not replicate in warm temperatures of the lungs and other parts of the body. However, as the temperature in the cooler nose, the virus that causes minor infections in the nose. This infection causes no symptoms in most people, but in some people it causes symptoms such as runny nose and sore throat, says Schaffner.

This local infection will prompt the body to make antibodies against the flu virus, said Schaffner. “It provides better protection against the real flu, which of course, is a virus that can make you very ill,” says Schaffner.

Children younger than 6 months can not get a flu shot. Those who already have a severe allergic reaction to the flu vaccine in the past should generally not be vaccinated, the CDC said.

You do not have to get a flu shot if you have a high fever. (You have to wait until the fever is gone.)

However, if you have a minor illness, such as mild colds or headaches, you can still get a flu shot, says Schaffner. “The vaccine is not perfect either in people.”
