Albert Burla, CEO of Pfizer, noted that “a reasonable assumption is that a third dose will likely be necessary, between six and twelve months, and from there there will be a vaccination again every year, but all this must be confirmed”, in the statements issued. Thursday by CNBC.
He added, “On the other hand, variables will play a major role.”
“It is very important to reduce the number of people exposed to the virus,” Burla said.
Earlier today, the Biden Administration’s anti-COVID cell director also stressed that Americans should expect to receive a booster vaccine in order to protect them from the spreading viral variants.
“We don’t know everything at this point,” admitted Dr. David Kessler, during a hearing before US parliamentarians.
“We are studying the duration of the antibody response,” he said. “It looks strong but it’s seeing a certain decline and the variations are challenging.”
“For logistical reasons, and for logistical reasons only, I think we have to consider that there might be a recall,” Kessler said.
The Pfizer / BioNTech Alliance had already announced in February that it was studying the effects of a third dose of its vaccine against variants in a clinical study.
This vaccine, which is given in two doses, uses an innovative RNA technology that has never been used before in real life, such as Moderna.
At this point, these two vaccines are considered to be the best performers, with an efficacy of 95% for Pfizer / BioNTech and 94.1% for Moderna against COVID-19, according to clinical studies.
