Misconceptions about Flu Vaccines

Tin can a flu vaccine give you lot flu?

No, flu vaccines cannot crusade flu affliction. Flu vaccines given with a needle (i.e., influenza shots) are fabricated with either inactivated (killed) viruses, or with only a single protein from the flu virus.  The nasal spray vaccine contains live viruses that are attenuated (weakened) so that they will non crusade illness.

Are any of the available flu vaccines recommended over the others?

For the 2021-2022 flu season, the Informational Committee on Immunization Practices (ACIP) recommends annual influenza (flu) vaccination for everyone 6 months and older with whatever licensed, flu vaccine that is advisable for the recipient's historic period and wellness condition, including inactivated influenza vaccine (IIV4), recombinant influenza vaccine (RIV4), or alive attenuated nasal spray influenza vaccine (LAIV4) with no preference expressed for any 1 vaccine over another.

There are many vaccine options to choose from, but the almost of import matter is for all people vi months and older to get a flu vaccine every year. If you have questions about which vaccine is best for you, talk to your medico or other health care professional person.

Is it better to become sick with influenza than to get a flu vaccine?

No. Flu can exist a serious disease, particularly amidst young children, older adults, and people with certain chronic health weather condition, such as asthma, centre disease or diabetes. Any influenza infection can carry a risk of serious complications, hospitalization or death, even amidst otherwise healthy children and adults. Therefore, getting vaccinated is a safer choice than risking affliction to obtain immune protection.

Do I actually demand a influenza vaccine every year?

Yes. CDC recommends a yearly influenza vaccine for everyone 6 months of historic period and older with rare exception. The reason for this is that a person's immune protection from vaccination declines over time, and then an annual vaccination is needed to go the "optimal" or best protection against the influenza. Additionally, influenza viruses are constantly changing, and so the vaccine composition is reviewed each yr and updated as needed based on which influenza viruses are making people ill.

Why do some people non feel well after getting a seasonal flu vaccine?

Some people report having balmy side furnishings after influenza vaccination. The virtually common side furnishings from flu shots are soreness, redness, tenderness or swelling where the shot was given. Low-grade fever, headache and muscle aches besides may occur. If these reactions occur, they ordinarily begin before long afterward vaccination and terminal 1-2 days. In randomized, blinded studies, where some people got inactivated influenza shots and others got table salt-water shots, the only differences in symptoms was increased soreness in the arm and redness at the injection site among people who got a flu shot. There were no differences in terms of trunk aches, fever, cough, runny nose or sore pharynx.

Side effects from the nasal spray influenza vaccine may include: runny olfactory organ, wheezing, headache, vomiting, muscle aches, fever, sore pharynx and cough. If these problems occur, they usually begin before long later on vaccination and are balmy and brusk-lived. The most mutual reactions people take to flu vaccines are considerably less severe than the symptoms caused by actual influenza illness.

What about serious reactions to influenza vaccine?

Serious allergic reactions to flu vaccines are very rare. If they do occur, information technology is usually within a few minutes to a few hours subsequently vaccination. While these reactions can be life-threatening, effective treatments are bachelor.

What about people who get a seasonal influenza vaccine and notwithstanding become sick with flu symptoms?

There are several reasons why someone might go flu symptoms, fifty-fifty subsequently they have been vaccinated confronting flu.

1. One reason is that some people tin can become sick from other respiratory viruses as well flu such as rhinoviruses, which are associated with the common common cold.  These viruses tin can cause symptoms like to flu, and also spread and cause illness during influenza flavour. Flu vaccines only protect against flu and its complications, non other illnesses.
2. Some other caption is that it is possible to exist exposed to flu viruses, shortly before getting vaccinated or during the two-week flow later vaccination that information technology takes the body to develop allowed protection. This exposure may issue in a person becoming sick with flu before protection from vaccination takes effect.
3. A 3rd reason why some people may experience influenza symptoms despite getting vaccinated is that they may take been exposed to a flu virus that is very different from the vaccine viruses. The ability of a flu vaccine to protect a person depends largely on the similarity or "match" between the vaccine viruses chosen to make vaccine and those spreading and causing illness. There are many different flu viruses that spread and cause disease among people. For more information, encounter Influenza (Flu) Viruses.
4. The final explanation for experiencing flu symptoms after vaccination is that influenza vaccines  vary in how well they work and some people who get vaccinated however go ill with flu. When that happens, though, vaccination has been shown in several studies to reduce severity of disease in those people who get vaccinated but still get sick.

Tin can vaccinating someone twice provide added immunity?

In adults, studies have not shown a do good from getting more than than one dose of vaccine during the same influenza season, even among elderly persons with weakened immune systems. Except for children getting vaccinated for the first time, only 1 dose of flu vaccine is recommended each season.

Is it true that getting a flu vaccine can make you more susceptible to other respiratory viruses?

Influenza vaccines are not thought to make people more susceptible to other respiratory infections.

A 2012 reportexternal icon that suggested that flu vaccination might make people more susceptible to other respiratory infections. Later on that report was published, many experts looked into this issue farther and conducted boosted studies to see if the findings could be replicated. No other studies have institute this event. It's not clear why this finding was detected in the one written report, but the majority of prove suggests that this is not a common or regular occurrence and that flu vaccination does non, in fact, make people more susceptible to other respiratory infections.

• Maria Sundaram et al. (2013). Influenza Vaccination Is Non Associated With Detection of Noninfluenza Respiratory Viruses in Seasonal Studies of Flu Vaccine Effectivenessexternal icon.

Does a flu vaccination increment your risk of getting COVID-19?

There is no testify that getting a flu vaccination increases your adventure of getting sick from a coronavirus, like the ane that causes COVID-19.

You may have heard about a studyexternal icon published in Jan 2022 that reported an association between influenza vaccination and risk of 4 ordinarily circulating seasonal coronaviruses, but not the one that causes COVID-nineteen. This report was afterwards found to exist incorrect.

The results from that initial report led researchers in Canada to look at their data to see if they could find similar results in their population. The results from Canada'due south studyexternal icon showed that flu vaccination did not increase take chances for these seasonal coronaviruses. The Canadian findings highlighted the protective benefits of flu vaccination.

The Canadian researchers too identified a flaw in the methods of the first study, noting that it violated the function of study blueprint that compares vaccination rates among patients with and without flu (test negative blueprint). This flaw led to the incorrect association between influenza vaccination and seasonal coronavirus risk. When these researchers reexamined data from the first study using correct methods, they found that flu vaccination did non increase risk for infection with other respiratory viruses, including seasonal coronaviruses.

Misconceptions about Flu Vaccine Effectiveness

Influenza (influenza) vaccine effectiveness (VE) can vary. The protection provided by a flu vaccine varies from season to season and depends in function on the historic period and wellness condition of the person getting the vaccine and the similarity or "match" between the viruses in the vaccine and those in circulation. During years when the flu vaccine lucifer is good, it is possible to measure substantial benefits from flu vaccination in terms of preventing flu affliction and complications. Nonetheless, the benefits of influenza vaccination will still vary, depending on characteristics of the person existence vaccinated (for case, their health and age), what influenza viruses are circulating that flavor and, potentially, which blazon of influenza vaccine was used. For more than information, see Vaccine Effectiveness – How well does the Flu Vaccine Work. For information specific to this season, visit Nigh the Current Flu Season.

There are many reasons to get an flu (flu) vaccine each year. Influenza vaccination is the all-time way to protect yourself and your loved ones against flu and its potentially serious complications.

Below is a summary of the benefits of flu vaccination and selected scientific studies that back up these benefits.

• Flu vaccination can keep you from getting sick with influenza.

• • Flu vaccination prevents millions of illnesses and influenza-related doctor's visits each year. For instance, during  2019-2020 influenza vaccination prevented an estimated 7.v million flu illnesses, three.7 one thousand thousand influenza-associated medical visits, 105,000 flu-associated hospitalizations, and 6,300 influenza-associated deaths.
  • During seasons when flu vaccine viruses are similar to circulating flu viruses, influenza vaccine has been shown to reduce the chance of having to go to the doctor with flu by 40 percent to 60 percentage.

• Flu vaccination has been shown in several studies to reduce severity of illness in people who get vaccinated simply still go ill.
  • A 2022 studyexternal icon showed that among adults, flu vaccination was associated with a 26% lower chance of ICU admission and a 31% lower gamble of death from flu compared to those who were unvaccinated.
  • A 2022 studyexternal icon showed that among adults hospitalized with flu, vaccinated patients were 59 percent less likely to be admitted to the ICU than those who had not been vaccinated. Amongst adults in the ICU with influenza, vaccinated patients on boilerplate spent 4 fewer days in the infirmary than those who were not vaccinated.

• Flu vaccination tin reduce the gamble of flu-associated hospitalization.
  • Flu vaccination prevents tens of thousands of hospitalizations each year. For case, during 2019-2020 influenza vaccination prevented an estimated 105,000 flu-related hospitalizations.
  • A 2022 studyexternal icon showed that influenza vaccination reduced children'southward risk of flu-related pediatric intensive care unit (PICU) admission past 74 percent during flu seasons from 2010-2012. A 2022 report found that during 2009-2016, flu vaccines reduced the risk of influenza-associated hospitalization among older adults by near 40 pct on boilerplate.
  • A 2022 study showed that from 2012 to 2015, flu vaccination among adults reduced the hazard of being admitted to an intensive intendance unit (ICU) with flu past 82 pct.

• Influenza vaccination is an important preventive tool for people with certain chronic wellness conditions.
  • Flu vaccination has been associated with lower rates of some cardiac eventsexternal icon among people with heart affliction, especially amidst those who have had a cardiac event in the past year.
  • Flu vaccination can reduce the take a chance of a flu-related worsening of chronic lung affliction (for example, chronic obstructive pulmonary illness (COPDexternal icon) requiring hospitalization.
  • Among people with diabetesexternal icon and chronic lung diseaseexternal icon ,flu vaccination also has been shown in separate studies to be associated with reduced hospitalizations from a worsening of their chronic condition.

• Influenza vaccination helps protect pregnant people during and after pregnancy.
  • Vaccination reduces the take a chance of flu-associated acute respiratory infection in pregnant people by about half.
  • A 2022 studyexternal icon showed that getting a flu shot reduced a pregnant person's risk of existence hospitalized with flu by an average of xl percent from 2010-2016.
  • A number of studies have shown that in addition to helping to protect significant people from influenza, a flu vaccine given during pregnancy helps protect the baby from flu for several months afterward birth, when he or she is too immature to be vaccinated.

• Flu vaccine tin can be lifesaving in children.
  • A 2022 study was the first of its kind to testify that influenza vaccination can significantly reduce a child'due south risk of dying from flu.

• Getting vaccinated yourself may also protect people around you, including those who are more vulnerable to serious flu illness, like babies and immature children, older people, and people with certain chronic wellness conditions.

Despite the many benefits offered by flu vaccination, just about half of Americans become an annual influenza vaccine and influenza continues to crusade millions of illnesses, hundreds of thousands of hospitalizations and tens of thousands of deaths. Many more people could be protected from flu if more people got vaccinated.

Misconceptions about the Timing of Seasonal Flu Vaccination

Should I wait to get vaccinated and so that my immunity lasts through the end of the season?

Flu Vaccine Finder

Detect flu vaccines in your area.
Everyone 6 months of age and older needs a influenza vaccine.

Find Vaccines

How long you are allowed or your "duration of immunity" is discussed in the ACIP recommendations. While delaying getting of vaccine until afterwards in the fall may pb to higher levels of amnesty during wintertime months, this should be balanced against possible risks, such as missed opportunities to receive vaccine and difficulties associated with vaccinating a big number of people within a shorter time catamenia.

Is it also late to get vaccinated subsequently Thanksgiving (or the end of November)?

No. Vaccination can still be beneficial as long as flu viruses are circulating. If you have not been vaccinated by Thanksgiving (or the end of November), it tin still be protective to become vaccinated in Dec or later. Influenza is unpredictable and seasons can vary.

No. There is no recommendation for pregnant women or people with pre-existing medical weather to seek special permission or secure written consent from their medico for vaccination if they get vaccinated at a worksite clinic, pharmacy or other location exterior of their doc's office. With rare exception, CDC recommends an annual flu vaccine for anybody vi months of age and older, including pregnant women and people with medical weather.

A variety of influenza vaccine products are available (Table 1). Vaccine providers should be aware of the approved historic period indications of the vaccine they are using and of any contraindications or precautions. Providers also should appropriately screen all people getting vaccinated for allergies to vaccine components or other contraindications. People who take previously had a severe allergic reaction to influenza vaccine or whatsoever of its ingredients should by and large not exist vaccinated.

There are some people who should not become a flu vaccine without kickoff speaking with their physician. These include:

• People who have a moderate-to-astringent disease with or without a fever (they should expect until they recover to become vaccinated), and
• People with a history of Guillain-Barré Syndrome (a severe paralytic illness, likewise chosen GBS) that occurred after receiving influenza vaccine and who are not at risk for severe illness from influenza should more often than not not receive vaccine. Tell your doctor if you ever had Guillain-Barré Syndrome. Your doctor volition help you decide whether the vaccine is recommended for you lot.

Significant women or people with pre-existing medical conditions who get vaccinated should get a flu shot.

If a person is vaccinated past someone other than their principal wellness care provider, the vaccinating provider should ensure that the patient and, if possible, the patient's medical provider have documentation of vaccination.

For a consummate list of people who should not become a influenza vaccine before speaking with their doctor, please review the flu Vaccine Data Statement for the inactivated or recombinant influenza vaccine or live, intranasal influenza vaccine.

Misconceptions about "Stomach Flu"
