Pfizer eyes COVID vaccine for all variants before 2023

Originally published on MedicalXpress Breaking News-and-Events ( April 14, 2022) – A COVID-19 vaccine effective against multiple variants is possible before the end of 2022, the head of US pharmaceutical giant Pfizer said Wednesday.

Chairman Albert Bourla said the firm was also working on producing a vaccine that could provide good protection for a whole year, meaning people would come back annually for boosters, as with influenza shots.

“I hope, clearly by autumn… that we could have a vaccine” that worked against not only the dominant Omicron but all known variants, he said.
