2019-2020 Influenza Vaccine Composition

During the 2017-2018 flu season, there were 959,000 hospitalizations and 80,000 deaths in the USA attributed to the flu.  It’s important to get vaccinated this year!

Every ingredient in the 2019-2020 influenza vaccine has a specific purpose.

Trivalent Vaccine:
* A/Brisbane/02/2018 (H1N1) pdm09-like virus
* A/Kansas/14/2017 (H3N2)-like virus
* B/Colorado/06/2017-like virus (Victoria lineage)

Quadrivalent Vaccine:
* The above three strains PLUS B/Phuket/3073/2013-like virus (Yamagata lineage)

Multi-dose influenza vials contain the preservative thimerosal (e.g. a chemical metabolized in the body to ethyl mercury).  Ethyl mercury crosses into the brain in very low amounts, but less so than methyl mercury.

Trace amounts of formaldehyde may be present from the manufacturing process.

Protein from eggs allow virus to grow before it is harvested.

Please talk with your doctor about which influenza vaccine is right for your health needs.  Additionally, many pharmacists have been trained to help immunize and educate the public on vaccine facts.
