Pfizer CEO: Vaccine third dose 'likely' needed within 12 months

The head of Pfizer said in an interview aired on April 15 that people will "likely" need a third dose of his company's COVID-19 shot within six to 12 months of vaccination, while elsewhere defending the relatively higher cost of the jab.

CEO Albert Bourla also said annual vaccinations against the coronavirus may well be required.
