There is a good chance that one day the variant of Covid will show that the vaccine is not resistant to it. This message comes with the CEO of Pfizer, Albert Burla, in an interview with the US channel Fox News.
“Every time a variable appears in the world, our scientists work on it,” he says. They are investigating to see if the alternative could evade vaccine protection. We haven’t found anything like this yet, but we think it’s possible someday. Once that happens, we will need 95 days to develop a vaccine that specifically targets this species.”

Stephen van Gucht, a Sciensano virologist, also predicts that the delta variant will give way to a new species – “that’s for sure, it’s business as usual”. This alternative may better escape the accumulated immunity, but the horror scenario is unlikely. “A virus like this reaches its limit,” says Van Guchte. Compare it to the best sport: The Olympic high jump is in perfect shape and can’t get much better. It is about a centimeter. With the Delta variant, coronavirus is at the top of its game.”
Virologists have been saying this for some time: the faster the many people are vaccinated, the lower the chance of the virus mutating. Pfizer is currently testing the vaccine in children ages 5 to 11 — and results are expected in September. “Next, we’ll start with the under-fives,” Burla says.
Borla conducted the interview after the vaccine was finalized in the United States. So far, the United States has been operating with “emergency approval”, but in Europe the vaccine has been finally approved.
