Inactivated Influenza Vaccine
Flu Shot Side Effects - 2010/2011
By Centers for Disease Control and Prevention
Why get vaccinated for flu?
Influenza flu is a contagious disease. It is caused by the influenza virus, which can be spread by coughing, sneezing, or nasal secretions.
Anyone can get influenza, but rates of infection are highest among children. For most people, symptoms last only a few days.
Flu Symptoms include:
- Sore throat
- Muscle aches
Other illnesses can have the same symptoms and are often mistaken for influenza.
Infants, the elderly, pregnant women, and people with certain health conditions such as heart, lung or kidney disease or a weakened immune system can get much sicker. Flu can cause high fever and pneumonia, and make existing medical conditions worse. It can cause diarrhea and seizures in children. Each year thousands of people die from seasonal influenza and even more require hospitalization. By getting vaccinated you can protect yourself from influenza and may also avoid spreading influenza to others.
Who should get inactivated influenza vaccine and when?
There are two types of influenza vaccine:
1. Inactivated (killed) vaccine, or the flu shot is given by injection into the muscle.2. Live, attenuated (weakened) influenza vaccine is sprayed into the nostrils. This vaccine is described in a separate Vaccine Information Statement.
A high-dose inactivated influenza vaccine is available for people 65 years of age and older. Ask your health care provider for more information.
Influenza viruses are always changing, so annual vaccination is recommended. Each year scientists try to match the viruses in the vaccine to those most likely to cause flu that year.
The 2010-2011 vaccine provides protection against A/H1N1 (pandemic) influenza and two other influenza viruses influenza A/H3N2 and influenza B. It will not prevent illness caused by other viruses.
WHO should get a flu shot?
All people 6 months of age and older should get flu vaccine.
Vaccination is especially important for people at higher risk of severe influenza and their close contacts, including health care personnel and close contacts of children younger than 6 months.
People who got the 2009 H1N1 (pandemic) influenza vaccine, or had pandemic flu in 2009, should still get the 2010-2011 seasonal influenza vaccine.
WHEN to get a flut shot?
Getting the vaccine as soon as it is available will provide protection if the flu season comes early. You can get the vaccine as long as illness is occurring in your community. influenza can occur at any time, but most influenza occurs from November through May. In recent seasons, most infections have occurred in January and February. Getting vaccinated in December, or even later, will still be benefi cial in most years.
Adults and older children need one dose of influenza vaccine each year. But some children younger than 9 years of age need two doses to be protected. Ask your health care provider.
Influenza vaccine may be given at the same time as other vaccines, including pneumococcal vaccine. Many Vaccine Information Statements are available in Spanish and other languages.

Inactivated influenza vaccine
It takes up to 2 weeks for protection to develop after the shot. Protection lasts about a year. Some inactivated influenza vaccine contains a preservative called thimerosal. Thimerosal-free influenza vaccine is available. Ask your healthcare provider for more information. Some people should not get inactivated influenza vaccine or should wait
Tell your health care provider if you have any severe (life-threatening) allergies. Allergic reactions to influenza vaccine are rare.
- Influenza vaccine virus is grown in eggs. People with a severe egg allergy should not get influenza vaccine.
- A severe allergy to any vaccine component is also a reason not to get the vaccine.
- If you ever had a severe reaction after a dose of influenza vaccine, vere paralytic illness, also called GBS). Your provider will help you decide whether the vaccine is recommended for you.
People who are moderately or severely ill should usually wait until they recover before getting flu vaccine. If you are ill, talk to your health care provider about whether to reschedule the vaccination. People with a mild illness can usually get the vaccine.
What if there is a severe reaction?
What should I look for?
Any unusual condition, such as a high fever or behavior changes. Signs of a severe allergic reaction can include diffi culty breathing, hoarseness or wheezing, hives, paleness, weakness, a fast heart beat or dizziness.
What should I do?
Call a doctor, or get the person to a doctor right away. Tell the doctor what happened, the date and time it happened, and when the vaccination was given.
Ask your health care provider to report the reaction by filing a Vaccine Adverse Event Reporting System (VAERS) form. Or you can file this report through the VAERS website at www.vaers.hhs.gov, or by calling 1-800-822-7967. VAERS does not provide medical advice.
How can I learn more?
Ask your health care provider. They can give you the vaccine package insert or suggest other sources of information. Call your local or state health department.

What are the risks from inactivated influenza vaccine?
A vaccine, like any medicine, could possibly cause serious problems, such as severe allergic reactions. The risk of a vaccine causing serious harm, or death, is extremely small.
Serious problems from inactivated influenza vaccine are very rare. The viruses in inactivated influenza vaccine have been killed, so you cannot get influenza from the vaccine.
Mild side effect problems:
- soreness, redness, or swelling where the shot was given
- sore, red or itchy eyes
- cough fever aches
If these problems occur, they usually begin soon after the shot and last 1-2 days.
Severe side effect problems:
Life-threatening allergic reactions from vaccines are very rare. If they do occur, it is usually within a few minutes to a few hours after the shot.
1 or 2 cases per million people vaccinated get Guillain-Barre Syndrome
In 1976, a type of inactivated influenza (swine flu) vaccine was associated with Guillain-Barre Syndrome (GBS). Since then, flu vaccines have not been clearly linked to GBS. However, if there is a risk of GBS from current flu vaccines, it would be no more than 1 or 2 cases per million people vaccinated. This is much lower than the risk of severe influenza, which can be prevented by vaccination.
The National Vaccine Injury Compensation Program
The National Vaccine Injury Compensation Program (VICP) was created in 1986.
People who believe they may have been injured by a vaccine can learn about the program and about fi ling a claim by calling 1-800-338-2382, or visiting the VICP website at www.hrsa.gov/vaccinecompensation.
One brand of inactivated flu vaccine, called Afluria, should not be given to children 8 years of age or younger, except in special circumstances. A related vaccine was associated wi tell your health care provider. Tell your health care provider if you ever had Guillain-Barre Syndrome (a seth fevers and fever-related seizures in young children in Australia. Ask your health care provider for more information.

Published studies surveying health care workers in Hong Kong, United Kingom, Germany, Switerland, Australia and the United States indicate acceptance and fears of vaccination dangers.
"FluMist recipients Can Infect Immunocompromised Individuals For At Least 21 Days."
According to the Mayo Clinic, the swine flu scandal of 1976, when more people died from the vaccine than the actual virus, caused the live viruses to be removed from future vaccines. However, it is admitted that FluMist contains the live virus.
"It has been documented that the live viruses from the vaccine can be shed (and potentially spread into the community) from recipient children for up to 21 days, and even longer from adults. Viral shedding also puts breastfeeding infants at risk if the mother has been given FluMist," writes Dr. Sherri Tenpenny, one of the most outspoken physicians in the country on the hazards of vaccines and vaccination.
FluMist’s own package insert reads as follows, "FluMist® recipients should avoid close contact with immunocompromised individuals for at least 21 days."
"The warning is specifically directed toward those living in the same household with an immunocompromised person, but the on-going release of live viruses throughout the community may be a significant risk to everyone who has a weak, or weakened, immune system," writes Tenpenny, pointing out that if one takes into account a plethora of health conditions that could be classified as contributing to immunodeficiency, as much as 60% of the entire population could be considered to be "chemically immunosuppressed."
"There is no evidence that any influenza vaccine thus far developed is effective in preventing or mitigating any attack of influenza. The producers of these vaccines know that they are worthless, but they go on selling them anyway."
