A third dose of Pfizer’s Covid-19 vaccine will “likely” be needed within 12 months of receiving the previous two doses, the Pfizer CEO said.
In addition, “he also said that it was possible that people would need to be vaccinated against the virus every year,” reports CNBC.
The news was revealed by CNBC in comments from Albert Bourla, CEO of Pfizer, on April 1.
“It is extremely important to remove the pool of people who may be susceptible to the virus,” he told CNBC’s Bertha Coombs at an event with CVS Health. He added that vaccines will be an important tool in the fight against highly contagious variants.
Researchers still don’t know how long the protection lasts after a person has been fully vaccinated.
Despite clinical trials, Pfizer researchers say they still don’t know whether vaccines “protect” for more than six months.
The company said it was testing a vaccine booster in February, noting that “the rate of mutations in the current virus is higher than expected.”
“There is a reasonable probability that we will end up with steady increases,” said Scientific Director Mikael Dolsten. “And for strong vaccines, you may need to change the strain every few years, but not necessarily every year.”
Currently, the CDC recommends injecting the second dose of the Pfizer / BioNTech vaccine 21 days after the first vaccine.
The number of deaths from the Covid-19 vaccine continues to rise
