Why You May Still Get Sick After a Flu Shot

No, the flu vaccine can not cause the flu. flu vaccine is given with a needle (ie, the flu shot) is currently made in two ways: a vaccine made either with) flu virus that has been ‘inactive’ (killed) and therefore not contagious, or b) using only a single gene from the virus flu (as opposed to a full virus) to generate an immune response without causing infection. This is the case for.

For the 2019-2020 flu season, which recommends influenza (flu) annual vaccination for everyone 6 months and older with each licensed influenza vaccine, which is appropriate for the age and health status of the recipient, including attenuated influenza vaccine ( IIV), a recombinant influenza vaccine (RIV), or live attenuated nasal spray influenza vaccine (LAIV4) without the expressed preference for any one vaccine over the other.

No to choose from, but 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.

No. Flu can be a serious illness, especially among children, older adults, and people with certain chronic health conditions, such as asthma, heart disease or diabetes. Each flu infection may carry the risk of serious complications, hospitalization or death, even among healthy children and adults. Therefore, getting vaccinated is a safer option than risking disease to get immune protection.

Yes. The CDC recommends annual flu vaccine for nearly everyone 6 months and older, even when the vaccine protects against the virus has not changed from the previous season. The reason for this is that a person’s immune protection from vaccination declines over time, so annual vaccination is needed to get “optimal” or best protection against the flu.

Some people have reported mild reactions to flu vaccination. The most common side effects from the flu shot are pain, redness, tenderness or swelling where the shot was given. mild fever, headache and muscle pain can also occur. If these reactions occur, they usually begin soon after the shot and last 1-2 days. In a randomized, blind study, in which some people get a flu shot is off and others get the picture salty water, the only differences in symptoms of increased pain in the arm and redness at the injection site among people who got a flu shot. , There is no difference in terms of body aches, fever, cough, runny nose or sore throat

The side effects of the flu vaccine nasal spray may include: runny nose, wheezing, headache, vomiting, muscle, fever, sore throat and cough. If these problems occur, they usually begin soon after vaccination and mild and short-lived. The most common reaction people have flu vaccine is much more severe than the symptoms caused by the actual flu.

serious allergic reactions to the flu vaccine are very rare. If they do occur, usually within a few minutes to a few hours after the vaccination. While this reaction can be life-threatening, effective treatment is available.

There are several reasons why someone might get flu symptoms, even after they have been vaccinated against the flu.

In adults, studies have not shown benefit from getting more than one dose of influenza vaccine during the same season, even among older people with weakened immune systems. , Only one dose of flu vaccine is recommended every season.

There are (published in 2012) which states that influenza vaccination may make people more susceptible to other respiratory infections. After the study was published, many experts look into the matter further and do additional studies to see if these findings can be replicated. No other studies have found this effect. For example, in Clinical Infectious Diseases (published in 2013). It is not clear why this finding was detected in one study, but the preponderance of evidence shows that this is not a general or a regular occurrence and that influenza vaccination was not, in fact, making people more susceptible to other respiratory infections.

Influenza (flu) vaccine effectiveness (VE) can be varied. The protection afforded by the flu vaccine depending on the age and health status of people who get the vaccine, and the similarity or “match” between the virus in the vaccine and those in circulation. For more information, see. for inspecial formation for this season, visit.

There are many reasons to get influenza (flu) vaccine every year. The following is a summary of the benefits of flu vaccination, and the scientific studies that have that support these benefits.

* References to studies listed above can be found. Also, see Fact Sheet.

The CDC recommends that people get the flu vaccine at the end of October. Getting vaccinated later, however, still be useful. During the flu virus in circulation, it is not too late to get vaccinated, even in January or later. While seasonal flu outbreaks can occur in early October, most of the time influenza activity peaks between December and February, although the activity can take place until the end of May. Because it takes about two weeks after vaccination for antibodies to develop in the body that protect against influenza virus infection, it is best that people get vaccinated in time to be protected before flu starts spreading in their communities.

How long have you invulnerable or “duration of immunity” You discussed in. While the delay getting the vaccine until later in the fall can cause a higher level of immunity during the months of winter, this must be balanced against the possible risks, such as the loss of an opportunity to receive the vaccine and the difficulties associated with vaccination of large numbers of people in a shorter period of time period.

No. Vaccination may still be useful during the flu virus in circulation. If you have not been vaccinated by Thanksgiving (or the end of November), they can be protective to get vaccinated in December or later. Flu season is unpredictable and can vary. Seasonal flu usually peaks between December and March most years, but the disease can occur until the end of May.

No. No recommendation for or people with medical conditions that already exist for requesting special permission or securing written approval from their doctor for a vaccination if they get vaccinated at a workplace clinic, pharmacy or other location outside of their doctor’s office. With rare exception, the CDC recommends an annual flu vaccine for everyone 6 months and older, including pregnant women and people with medical conditions.

Providers should also be appropriate filter everyone get vaccinated for allergy to a vaccine component or other contraindications.
