LThe news reminds that, despite vaccinations, Covid-19 will not disappear overnight. People who receive the Pfizer vaccine will “probably” need a third dose within six months or a year, and then probably an injection every year, the head of the American pharmaceutical giant said. “The plausible hypothesis is that a third dose is likely to be needed between six months and twelve months, and then vaccinated again every year, but this has to be confirmed,” said Albert Burla, CEO of Pfizer. statements released Thursday by CNBC.
“On the other hand, options will play a key role,” he added. “It is extremely important to minimize the number of people vulnerable to the virus as much as possible,” continued Albert Burla. Earlier today, the director of the Biden administration’s Covid division also pledged that Americans should expect revaccinations to protect them from circulating variants of the coronavirus.
“Options – Challenge”
“At the moment we do not know everything,” admitted D.R David Kessler during a hearing before American parliamentarians. “We’re looking at the duration of the antibody response,” he said. “She looks strong, but she’s getting a little worse, and options are a problem.” “For logistical reasons, and only for logistical reasons, I think we should consider the possibility of a recall,” said Albert Kessler.

In February, the Pfizer-BioNTech alliance already announced a study of the effects of a third dose of its vaccine on variants as part of a clinical trial. This two-dose vaccine uses, like Moderna, an innovative RNA messenger technology never seen before in real life. According to clinical studies, at this stage, these two vaccines are the most effective: 95% for Pfizer-BioNTech and 94.1% for Moderna against Covid-19.
