  • Cell Culture-based Inactivated Influenza Vaccine (ccIIV3)

  • Recombinant Influenza Vaccine (RIV)

  • Live, Attenuated Influenza Vaccine (LAIV)

  • Reporting Adverse Events

  • The National Vaccine Injury Compensation Program

CDC and FDA screen the wellbeing of all vaccines authorized in the United States, including occasional influenza vaccines. This rundown gives data on:

  • Safety of inactivated influenza vaccine (IIV), cell culture-based inactivated influenza vaccine (ccIIV3), recombinant influenza vaccine (RIV), and live weakened influenza vaccine (LAIV), including adverse occasions following vaccination, contraindications, and safety measures.

1. Adverse Event Following Immunization (AEFI):
Adverse wellbeing occasions or medical conditions that happen following or during organization of a vaccine, that may be brought about by the vaccine or may be fortuitous and not identified with inoculation.

Inactivated Influenza Vaccine (IIV)

Studies support the wellbeing of yearly IIV immunization in kids and grown-ups. IIV is directed as an injection and may cause torment, redness, and growing at the injection site, and may likewise cause fever, disquietude and myalgias, which are typically gentle and disappear all alone.
