Those who are now vaccinated with Pfizer / BioNTech’s corona vaccine will likely need an extra shot within a year to stay protected against the virus. Pfizer CEO Albert Bourla reported this on Thursday.

“It is very important to keep the group of people susceptible to the virus as small as possible,” the CEO told CNBC.
He also indicated that it is possible that people will eventually have to be vaccinated against the corona virus every year.
Pfizer said in February that it is testing so-called “booster vaccines”, which would be administered after the two doses needed to protect against the coronavirus. And Moderna, which, like Pfizer, developed an mRNA vaccine, is also researching booster vaccines.
Earlier in the day, the White House corona cell had also warned that Americans would likely receive a call to get themselves vaccinated a third time. “We don’t know everything at the moment,” Dr. David Kessler told Congress. “We are investigating how long the antibodies react to the vaccines. The reaction seems strong, but it is decreasing and the virus variants are also a challenge. ”
