FDA says fourth vaccine dose might be needed

MILWAUKEE, (CBS 58) -- An FDA official is suggesting a fourth dose of the COVID-19 vaccine might be needed closer to fall.

Dr. Peter Marks says the FDA is continually monitoring pandemic data to track emerging variants.

Because fall is typically the timeline for flu shots, the same could be true for an additional COVID booster.

At the current time, a fourth shot is only recommended for immunocompromised people.

Both FDA and CDC scientists will have to agree before a fourth vaccine dose is added for the general public.
