What should I know About Influenza Vaccine?

  • Can a flu vaccine give me flu?

    No, a flu vaccine cannot cause flu illness. Flu shots (through needle) are made either with flu vaccine viruses that have been killed (inactivated) or with proteins from a flu vaccine virus, and are therefore not infectious.


  • How long does immunity from influenza vaccine last?

    Protection from influenza vaccine is thought to persist for at least 6 months. Protection declines over time because of waning antibody levels and because of changes in circulating influenza viruses from year to year. Hence an influenza shot is recommended every year.


  • Who Should Not Be Vaccinated?

    Different influenza vaccines are approved for use in different age groups. Factors that can determine a person’s suitability for vaccination, or vaccination with a particular vaccine, include a person’s age, health (current and past) and any allergies to influenza vaccine or its components.


  • Is it safe for pregnant women to get a flu shot?

    Yes. Pregnant women are at a higher risk of flu than others. Flu shots have been given to millions of pregnant women over many years. But we recommend consulting your doctor before going ahead.


Myths Vs Facts

  • Myth: I am worried that the flu vaccine can give me a flu

    Fact: It is a misconception about flu vaccines. A flu shot cannot cause the flu illness as it does not contain the active virus

  • Myth: I had a flu shot before, hence I am protected for life.

    Fact: Flu strains may differ from season to season, so you may need vaccination to protect against currently circulating viruses
