The scientist who helped develop the Pfizer-BioNTech COVID-19 vaccine stated a brand new model of the shot could also be wanted subsequent yr to guard towards the virus.
Dr. Ugur Sahin, BioNTech’s co-founder and CEO, stated that whereas booster photographs are efficient towards present strains, together with the contagious Delta variant, there could also be mutations that evade it sooner or later.
“This year [a different vaccine] is completely unneeded. But by mid-next year, it could be a different situation,” Sahin told the Financial Times.
The firm’s booster shot makes use of the identical formulation as its authentic two-dose vaccine.
But Sahin stated subsequent yr might name for brand new formulation which can be “tailored” to particularly goal options of the brand new variants.
“This virus will stay, and the virus will further adapt,” he advised the outlet. “We have no reason to assume that the next-generation virus will be easier to handle for the immune system than the existing generation. This is a continuous evolution, and that evolution has just started.”
BioNTech co-founder Dr. Ozlem Tureci, who can be Sahin’s spouse, predicted final week that booster photographs could also be wanted “every 12 to 18 months.”
“For all these variants which are currently circulating, it seems that boosters alone, bringing the waning immune responses back to high levels, are suitable and do protect,” Tureci told CNBC.
“However, we have to continue to screen because there might be variants upcoming for which this is not the case. And for this we have a second pillar, namely that we prepare ourselves to be quick and fast in the case that we need to adapt to a variant … And we are doing those dry runs, not alone, together with regulators, so that they are also prepared for the potential need to switch.”
