Flu Vaccine FAQ’s

What's the difference between vaccines?

  • Regular Flu Shot (Intramuscular): The regular flu shot contains killed flu viruses. It is injected into the muscle. It is approved for people ages 6 months and older.
  • High Dose Flu Shot: High Dose flu vaccine contains killed flu viruses. It is injected into the muscle. High Dose flu vaccine contains 4 times the amount of antigen as the regular flu shot. Antigen is the part of the flu vaccine that prompts the body to make antibodies. Additional antigen is intended to create a stronger immune response. It is approved for people ages 65 and older.

Who is recommended for flu vaccination this year?

CDC recommends all people ages 6 months and older get a flu vaccination. Vaccination is the single best way to protect yourself from the flu. While flu vaccination is recommended for everyone ages 6 months and older, some are especially at high risk for severe complications from the flu:

  • Pregnant women
  • Children younger than 5, but especially children younger than 2 years old
  • People 50 years of age and older
  • People of any age with certain chronic medical conditions
  • People who live in nursing homes and other long-term care facilities
  • People who live with or care for those at high risk for complications from flu, including:
    • Healthcare workers
    • Household contacts of persons at high risk for complications from the flu
    • Household contacts and out of home caregivers of children less than 6 months of age

Who CANNOT get a flu vaccination?

  • People who have a severe allergy to chicken eggs.
  • People who have had a severe reaction to a flu vaccination.
  • People who develop Guillain-Barre syndrome (GBS) within 6 weeks of getting a flu vaccine.
  • Children younger than 6 months of age (no flu vaccine is approved for this age group).
  • People who have a moderate-to-severe illness with a fever (wait until recovered to get vaccinated)

Does flu vaccine contain mercury?

  • Single dose pre-filled syringes of flu vaccine do not contain the mercury preservative thimerosal. Only multi-dose vials of vaccine contain a mercury preservative. Most of the vaccine UCHD uses is single dose pre-filled syringe without preservatives. We do use some multi-dose vials of vaccine. Please talk to our staff prior to getting vaccinated if you have any questions or concerns.

Will the flu shot make me sick?

  • No, a flu shot cannot cause the flu. The viruses contained in flu shots are inactivated (killed), which means they cannot cause infection. Flu vaccine manufacturers kill the viruses used in the flu shot during the process of making vaccine, and batches of flu vaccine are tested to make sure they are safe.

What about people who get a flu vaccine and still get sick with flu-like symptoms?

  • There are several reasons why someone might get flu-like symptoms even after they have been vaccinated against the flu.
    1. People may be exposed to a flu virus shortly before getting vaccinated or during the two-week period that it takes the body to gain protection after getting vaccinated. This exposure may result in a person becoming ill with flu before the vaccine begins to protect them.
    2. People may become ill from other (non-flu) viruses that circulate during the flu season, which can also cause flu-like symptoms (such as rhinovirus).
    3. A person may be exposed to a flu virus that is not included in the flu vaccine. There are many different influenza viruses that circulate every year. The flu shot protects against the 3 viruses that research suggests will be most common. Unfortunately, some people can remain unprotected from flu despite getting the vaccine. This is more likely to occur among people that have weakened immune systems. However, even among people with weakened immune systems, the flu vaccine can still help prevent influenza complications.
