On Tuesday, the U.S. Food and Drug Administration’s independent experts on

14

the Vaccines and Related Biological Products Advisory Committee met to publicly

15

discuss whether a change to the current vaccine strain composition of COVID-19

16

vaccines for booster doses is necessary for the 2022 fall and winter seasons.

18

The COVID-19 vaccines that the FDA has approved and authorized for

19

emergency use have made a tremendous difference to public health and have

20

saved countless lives in the U.S. and globally. However, SARS-CoV-2, the virus

21

that causes COVID-19, has evolved significantly, with recent surges around the

22

world associated with the rapid spread of highly transmissible variants such as

23

omicron.

24
25

Currently available vaccines have helped reduce the most serious outcomes

26

(hospitalization and death) caused by COVID-19, but results from post-

27

authorization observational studies have shown that effectiveness of primary

28

vaccination wanes over time against certain variants, including omicron. And

29

while initial booster doses have helped restore protection against severe disease

30

and hospitalization associated with omicron, studies have also indicated waning

31

effectiveness of first booster doses over time.
