Citizens will have to receive a coronavirus vaccine every year for a long time. Albert Bourla, the Chief Executive Officer of Pfizer, announced the information, the BBC writes.
He said citizens must maintain "strong protection against the virus."
Bourla noted that Pfizer has already developed vaccines against the coronavirus "beta" and "delta" variants, but their need has not been put on the agenda.
Now the company is working on a vaccine against "Omicron," which will be ready in 100 days.
"Vaccination has saved millions of lives, and without it, the fundamental structure of our society would be in jeopardy," Bourla said.
