Does Flu Shot Have Egg

Must read

Find Out Exactly Whats In The Flu Shot For 2021

Flu Shot ‘Egg’cellent for Most

Theres been a lot of talk about vaccines and vaccine ingredients lately thanks to the COVID-19 vaccine. And now that flu season upon us, its only natural to wonder about whats in your flu vaccine, too.

Like the COVID-19 vaccines, there are several types of seasonal flu vaccines. Some are egg-based, for example, while others are egg-free. There are also differences between the flu shot and nasal mist, and small nuances with high-dose flu vaccines and regular vaccines. For this flu season, the Food and Drug Administration has released nine different lots of the flu vaccine, and each is slightly different with its own ingredients. Still, they have a lot in common.

The flu vaccines are very similar in their general composition, says infectious disease expert Amesh A. Adalja, M.D., a senior scholar at the Johns Hopkins Center for Health Security. However, some use different technologies.

Sowhats in your seasonal flu vaccine and why? Experts break it down.

People Who Shouldnt Have The Vaccination

Almost everybody can have the vaccine, but you should not be vaccinated if you have ever had a serious allergy to the vaccine, or any of its ingredients. If you are allergic to eggs or have a condition that weakens your immune system, you may not be able to have certain types of flu vaccine check with your GP. If you have a fever, the vaccination may be delayed until you are better.

What Are The Flu Vaccine Side Effects

Common flu shot reactions include redness, soreness, or swelling in the area where the shot was administered. The nasal spray could cause different side effects, such as runny nose, sore throat, or a cough. These side effects are usually mild and short-lived.

Some people may also develop a low-grade fever or body aches. Similar to the other side effects, these symptoms are usually mild and quickly go away on their own. While some of these side effects may feel flu-like, it’s important to remember that flu vaccines will not make you sick with the flu.

Allergic reactions to the flu shot are rare.

Flu Vaccine For Frontline Health And Social Care Workers

If you’re a frontline health and social care worker, your employer should offer you a flu vaccine. They may give the vaccine at your workplace.

You can also have an NHS flu vaccine at a GP surgery or a pharmacy if:

  • you’re a health or social care worker employed by a registered residential care or nursing home, registered homecare organisation or a hospice
  • you work in NHS primary care and have direct contact with patients this includes contractors, non-clinical staff and locums
  • you provide health or social care through direct payments or personal health budgets, or both

How Effective Is The Flu Shot

Prevention and Control of Influenza with Vaccines ...

The vaccine formulation changes every year to try to “match” the influenza viruses that are spreading in our communities. The vaccine is more effective when it has a good match. Even if a flu vaccine was not well-matched, it is still beneficial to get vaccinated. If you do get the flu after vaccination, influenza illness may be less severe than if you had not been vaccinated. Getting vaccinated also helps to protect your community by promoting herd immunity.

How well the vaccine works varies from year to year. Overall, receiving the flu vaccine usually reduces the risk of getting the flu by between 40% and 60% among most people when the vaccine is well-matched with the isolated virus. Some people respond better than others to the flu vaccine and build stronger immunity. People that are older than 65 years typically build weaker immune responses to the influenza vaccine which is why there are special flu vaccines made especially for seniors.

Iii2 People Capable Of Transmitting Influenza To Those At High Risk Of Influenza

People who are potentially capable of transmitting influenza to those at high risk should receive annual vaccination, regardless of whether the high-risk individual has been vaccinated. Vaccination of HCWs decreases their own risk of illnessFootnote 52,Footnote 53, as well as the risk of death and other serious outcomes among the individuals for whom they provide careFootnote 54,Footnote 55,Footnote 56,Footnote 57. Vaccination of HCWs and residents of nursing homes is associated with decreased risk of ILI outbreaksFootnote 58.

People who are more likely to transmit influenza to those at high risk of influenza-related complications or hospitalization include:

  • HCWs and other care providers in facilities and community settings who, through their activities, are capable of transmitting influenza to those at high risk and
  • Contacts, both adults and children, of individuals at high risk, whether or not the individual at high risk has been vaccinated.

Vaccination of health care workers and other care providers
Outbreak management in health care facilities

Contacts of individuals at high risk of influenza complications

Who Should Not Get A Flu Vaccine

Talk to a board-certified allergist about the flu vaccine if your child has ever had a:

  • Life-threatening allergic reaction after a dose of flu vaccine
  • Severe allergy to any part of a flu vaccine

If you or your child has an egg allergy and you are still concerned about getting the flu shot, talk with an allergist.

I’ve Heard There Are Different Flu Vaccines Available Which One Is Right For Me

There are several different flu vaccines, and your pharmacist or other health care provider can help find the right vaccine for you. The CDC recommends that everyone ages 6 months and older receive the flu vaccine each year. The CDC does not recommend one flu vaccine over another the most important thing is that you get a flu vaccine every year.

All flu vaccines are quadrivalent , meaning they are designed to protect against four different flu viruses. The flu shots are injections that are administered into your upper arm. The flu shots do not contain a live virus and are either inactivated or recombinant .

There is also a nasal spray. The nasal spray contains live-attenuated influenza virus and is quadrivalent. The nasal spray flu vaccine may be an option for healthy people between the ages of 2 and 49 years who aren’t pregnant or have a weakened immune system.

People who are 65 years and older have additional options. Older adults have the option of receiving either a high dose or adjuvanted flu vaccine. These flu shots are specifically formulated for seniors and in past studies, have demonstrated better protection against the flu in persons ages 65 and older.

What Are The Types Of Flu Vaccines

CDC offers new recommendations when it coems to flu shot and egg allergies

Two types of flu vaccine are available for the 20202021 flu season. Both protect against the four types of influenza virus that are causing disease this season::

  • the flu shot, which is injected with a needle
  • the nasal spray, a mist which gets sprayed into the nostrils

In the past, the nasal spray vaccine wasn’t recommended for kids because it didn’t seem to work well enough. The newer version appears to work as well as the shot. So either vaccine can be given this year, depending on the child’s age and general health.

The nasal spray is only for healthy people ages 249. People with weak immune systems or some health conditions and pregnant women should not get the nasal spray vaccine.

Does The Flu Vaccine Contain Egg

Most versions of the flu shot and nasal spray vaccines can contain a tiny amount of egg protein. But studies show that the amount is so small it is unlikely that you will have a severe allergic reactions to the vaccines if you have an egg allergy.

There are also two vaccines that are egg free:

The risk of complications from the flu are greater than the risk of reaction from the tiny amount of egg in the vaccine.

BOTTOM LINE: It is safe for ALL people with an egg allergy to receive a flu vaccine every year. This is true no matter how severe your egg allergy was in the past. This includes anaphylaxis to egg.

Southern Hemisphere Influenza Season

The composition of virus vaccines for use in the 2018 Southern Hemisphere influenza season recommended by the World Health Organization on September 28, 2017, was:

  • an A/Michigan/45/2015 pdm09-like virus
  • an A/Singapore/INFIMH-16-0019/2016 -like virus
  • a B/Phuket/3073/2013-like virus

The WHO recommended that quadrivalent vaccines containing two influenza B viruses should contain the above three viruses and a B/Brisbane/60/2008-like virus.

Safety And Possible Side Effects

Prevention and Control of Seasonal Influenza with Vaccines

The CDC, U.S. Food and Drug Administration , National Institutes of Health , American Academy of Pediatrics , Advisory Committee on Immunization Practices , and National Academy of Sciences’ Institute of Medicine have all declared that the use of thimerosal in vaccines is safe and effective.

The safety profile of traditional and preservative-free flu shots are considered equal. Possible side effects of both thimerosal-containing vaccines and preservative-free vaccines include:

  • Pain and swelling at the injection site
  • Low-grade fever
  • Fatigue

Side effects are typically mild and resolve within a day or two.

However, if you develop wheezing, difficulty breathing, vomiting, rapid heartbeat, loss of consciousness, or swollen lips, tongue, or throat, call 911 or go to your nearest emergency room. These could be the signs of a rare and potentially life-threatening allergic reaction known as anaphylaxis.

Children Who Shouldnt Have The Vaccination

Children may not be able to have the nasal vaccine if they:

  • are currently wheezy or have been wheezy in the past 72 hours, they should be offered a suitable injected flu vaccine to avoid a delay in protection
  • have needed intensive care due to asthma or egg allergic anaphylaxis
  • have a condition, or are on treatment, that severely weakens their immune system or have someone in their household who needs isolation because they are severely immunosuppressed
  • are allergic to any other components of the vaccine
  • have a condition that needs salicylate treatment

Also, children who have been vaccinated with the nasal spray should avoid close contact with people with very severely weakened immune systems for around 2 weeks following vaccination because theres an extremely remote chance that the vaccine virus may be passed to them.

The Flu Shot And Egg Allergy

The influenza vaccine, also known as a flu shot, is a vaccine that protects against seasonal influenza . The CDC recommends everyone over the age of 6 months get the flu shot.

There is some confusion about who should not be vaccinated against influenza, particularly among those with an allergy to chicken egg. Influenza vaccines typically contain a small amount of egg protein. Fortunately, recent studies have shown that even people with egg allergy can safely receive the flu vaccine. The American Academy of Allergy Asthma and Immunology and the American Academy of Pediatrics states that no special precautions are required for the administration of influenza vaccine to egg-allergic patients no matter how severe the egg allergy. Normal precautions for giving vaccines should still be followed as rare case of allergic reactions to vaccines of any type do still occur.

The Allergy Department at the Boulder Medical Center recognizes many patients and parents of pediatric patient with egg-allergy may be reluctant to immunize against the flu. Along with your primary are provider, we can help determine the appropriate type of flu shot for each patient given your age, health history and allergy status. We also are trained in recognizing and treating allergic reactions. The Allergy Department offers flu administration with monitoring for such individuals. Please contact us for more information and to schedule an appointment at 303-440-3083.

Delivery Of The Flu Shot In 2021

Not all flu shots are the same. Some arent even shots. Here are your 2021 flu vaccine options:

Nasal Spray: The nasal spray vaccine is the only kind to include a live attenuated influenza vaccine. Although it cant give you the flu, it does have a higher likelihood of inducing flu-like symptoms. This vaccine does not contain thimerosal or other preservatives. Its available only for patients aged 2 to 49.

For: People who cant stand the needle or jet spray or who want to avoid preservatives.

Inactivated shots are usually given with a needle, but Afluria Quadrivalent can be given to adults with a jet injector, which is basically a high-powered spray that penetrates the skin.

For: Needles can be used for everyone aged 6 months and older. The jet spray is approved for adults aged 18 to 64.

Is The Flu Vaccine Safe For People With Egg Allergy

How are eggs used to make flu vaccines?

Yes. If you have a current or past egg allergy, you can get the flu vaccine, even if you have had severe allergic reactions to egg. The same is true for children.

The following organizations recommend getting the flu shot every year, even if you have an egg allergy:

  • Asthma and Allergy Foundation of America
  • Centers for Disease Control and Prevention
  • American Academy of Pediatrics
  • American Academy of Allergy, Asthma, and Immunology
  • American College of Allergy, Asthma, and Immunology

You can get any flu vaccine, even if you have a history of mild or severe egg allergy. You can get the shot or nasal spray. You no longer need to be observed in a doctors office for 30 minutes after getting the vaccine if you have or had an egg allergy.

AAFA recommends the following:

  • Ages 6 months to 4 years should get the flu shot.
  • Ages 4 and older: If your asthma is under control with no symptoms, you can get the flu shot or the nasal spray vaccine.
  • Ages 4 and older: If you have recent asthma episodes or wheezing, get the flu shot.

Why Should People Get Vaccinated Against Flu

Influenza is a potentially serious disease that can lead to hospitalization and sometimes even death. Every flu season is different, and flu can affect people differently, but millions of people get flu every year, hundreds of thousands of people are hospitalized and thousands to tens of thousands of people die from flu-related causes every year. Flu can mean a few days of feeling bad and missing work or it can result in more serious illness. Complications of flu can include bacterial pneumonia, ear infections, sinus infections and worsening of chronic medical conditions, such as congestive heart failure, asthma, or diabetes. An annual seasonal flu vaccine is the best way to help protect against flu. Vaccination has been shown to have many benefits including reducing the risk of flu illnesses, hospitalizations and even the risk of flu-related death in children. While some people who get a flu vaccine may still get sick, flu vaccination has been shown in several studies to reduce severity of illness.

Ii Canadian Immunization Guide Chapter On Influenza: Clinical Information For Vaccine Providers

The Canadian Immunization Guide is written primarily for health care providers but it is also used by policy makers, program planners, and the general public. The CIG has been a trusted, reader-friendly summary of the vaccine statements provided by NACI since 1979.

The information in this section replaces the influenza chapter of the CIG and is adapted for inclusion in the NACI Statement on Seasonal Influenza Vaccine. With a new NACI Statement on Seasonal Influenza Vaccine required each year, readers will have quick access to the information that they require within one document, whether it is the relevant influenza vaccine information written primarily for frontline vaccine providers as is found in this section, or the more detailed technical information that is found in the rest of this statement, commencing in Section III.

Iv1 Inactivated Influenza Vaccine

IIVs contain standardized amounts of the HA protein from representative seed strains of the two human influenza A subtypes and either one or both of the two influenza B lineages . IIVs currently authorized for use in Canada are a mix of split virus and subunit vaccines, both consisting of disrupted virus particles. Split virus vaccines contain whole inactivated viruses split with detergent, ether, or both, while subunit vaccines are made of purified HA and NA. The amount of NA in the vaccines is not standardized. HA-based serum antibody produced to one influenza A subtype is anticipated to provide little or no protection against strains belonging to the other subtype. The potential for trivalent vaccine to stimulate antibody protection across B lineages requires further evaluation and may be dependent upon factors such as age and prior antigenic experience with the two B lineagesFootnote 79,Footnote 80,Footnote 81,Footnote 82,Footnote 83,Footnote 84.

Because of potential changes in the circulating influenza virus from year to year and waning immunity in vaccine recipients, annual influenza vaccination is recommended. Although NACI is aware of some recent studies that suggest that vaccine induced protection may be greater in individuals who have no recent vaccine history, optimal protection against influenza, season after season, is best achieved through annual influenza vaccinationFootnote 85,Footnote 86. NACI will continue to monitor this issue.
