TWO doses of vaccine are not enough against Covid-19. Albert Bourla, Pfizer’s CEO told CNBC that another dose could be needed. A scenario defined as “probable”. “We will need a third dose, about 6 to 12 months. From there, then, there will be an annual recall. But everything has to be confirmed. And, again, the variants will have a fundamental role “, explained Albert Bourla, who however underlines how the annual booster, at the moment, is only a hypothesis to be evaluated. Bourla also revealed that the production of vaccines has been increased: “We are planning to drastically increase our vaccine supplies to European countries in the coming weeks. We will deliver over four times more this quarter than we did in the first quarter: 250 million doses, after giving 62 as of March. And we are in discussions to do more. I am confident that we will succeed. Of course, there is always a chance that something will go wrong, as seen by the problems other companies are having. Some questions can always arise when you are dealing with the complicated manufacturing of organic products “.

According to the CEO of Pfizer, the chances of a return to normality by autumn are real: “We see this from the example of Israel. Of course, it is a small country, with closed borders. The movements in and out are limited and the population lives in an almost continuous state of war, so they know how to respond quickly to a crisis. But there we were able to show the whole world that there is hope “. Meanwhile Pfizer has released the latest data on the quality of its vaccine: it has an efficacy of more than 91% against Coronavirus and more than 95% in contrasting the severe form of the disease even 6 months after the administration of the second dose.
