The approval by the FDA of the Pfizer anti-Covid vaccine for 12-15 year olds “will be very useful because it is the fundamental segment of the population without which herd immunity cannot be achieved”. This was stated by Guido Rasi, former executive director of the Ema drug agency and today consultant to the Commissioner for the coronavirus emergency, guest of ‘SkyTg24’. “As soon as the EMA receives the data, it will have no hesitation in approving it, indeed there will be a rush to approve it”, adds Rasi. The Food and Drug Administration has in fact authorized the Pfizer vaccine in the US for the 12-15 age group, according to what the Washington Post reported via Twitter in the last few hours. A green light expected for a few days, after Pfizer announced the results of its trial on adolescents, showing that the vaccine is at least as effective in that age group as it is in adults. The OK from the FDA now opens the vaccination campaign to millions of other Americans.
