Pfizer CEO unsure on need for fourth dose of COVID-19 vaccine

10 January 2022 21:20 (UTC +04:00)

Pfizer Inc (PFE.N) Chief Executive Officer Albert Bourla said on Monday he was unsure about the need for a fourth dose of COVID-19 vaccine and that a shot targeting the highly contagious Omicron variant would be ready in March, APA reports quoting Reuters.

The comments contrasted with those made by Moderna Inc (MRNA.O) CEO Stephen Bancel, who said last week people could need another shot in the fall of 2022 as the efficacy of boosters was likely to decline over the next few months.

A huge Omicron-driven spike in COVID-19 cases has forced some nations to look to another booster dose, but early signs suggest repeat vaccination may be a hard sell as beleaguered populations enter their third pandemic year.
