(Washington, DC) -- The CEO of Pfizer says people might need a fourth dose of the COVID vaccine.

Appearing on CBS' Face the Nation, Albert Bourla said the third dose protects against death and hospitalization, but not as strongly against infection. Pfizer also recently submitted data to the FDA concerning a fourth dose and was busy developing an annual COVID vaccine that would protect against all variants.

Bourla also mentioned building a better flu vaccine and tackling cancer treatments as Pfizer's goals for the future.
