He said,"I don't think that this means that the variants will not continue coming, and I don't think that this means that we should be able to live our lives without having vaccinations," Bourla said. "But that, again, remains to be seen."
His statement comes after Moderna chief Stephane Bancel said that the pandemic will get over in a year.
Scott Gottlieb, former Food and Drug Administration chief has also said that the current wave of Covid-19 cases which is driven by the Delta variant is going to be the end of Covid.
Bourla also said that most likely new variants might come out and also will have vaccines that will last at least a year and the most likely scenario is annual vaccination.
