Every new infection brings with it the risk that the coronavirus will change, that it will mutate – and thus could bypass the vaccination protection. The vaccines from Moderna and Pfizer / Biontech used in Switzerland work well against any mutations that occur today.

Hopefully it will stay that way. But in times of high infection rates, the risk of mutations increases – as it is now. Pfizer boss Albert Bourla (49) now considers a vaccine-resistant mutant to be “likely”, as he said in an interview with “Fox News”. It’s just a matter of time.
Would have to vaccinate from zero
Almost a year after the first emergency approval, the Pfizer and Biontech researchers are still working on the further development of their vaccine – and are checking whether their vaccine can withstand the virus variants. “So far we have not identified a mutant that can deprive our vaccine of protection,” says Bourla.
But what if this horror scenario did occur? “95 days after the variant was identified as causing concern, we will have a tailor-made vaccine against the variant,” assures the Pfizer boss. However, you would have to be vaccinated again from zero.
Pharma multi-Pfizer and the German biotech company Biontech, who jointly developed and market the vaccine, are currently working on two corona vaccine projects: On the one hand, a vaccine for children aged five and over is in the starting blocks. On the other hand, the researchers are busy developing a booster vaccination that should be highly effective against the Delta variant. (gif)
