VACCINES: the second DOSE of PFIZER produces more ANTIBODIES if DELAYED, according to a BRITISH STUDY. The details
The second DOSE of PFIZER produces more ANTIBODIES if DELAYEDIf the times of the RECALL of the coronavirus vaccine PFIZER up to 11-12 weeks, as the UK has already experienced since the start of its sprint vaccination campaign, the antibody response would be much stronger than that guaranteed with respect to the three weeks recommended by the company.
This is the result of one I study English, also reported by Repubblica, conducted byBirmingham University, but not yet officially published. After discussions about when to proceed with the second dose in Italy, with some regions announcing they want to delay the recall, and the Italian headquarters of theGerman company that advised to stick to what was decided after the trials, there could be a new breakthrough for German whey. Previous research, conducted byOxford Universityin February, it had already certified a general doubling of antibodies with the postponement of vaccine boosters, but the one published now by the University of Birmingham is the first to be based on the direct comparison of real cases among those who received the second dose after the standard interval and who after the extended interval.
The study was conducted on 175 British patients over 80 who have been vaccinated in recent months. Of these 99 received the second dose after three weeks, while 73 waited 12 weeks. The scientists then analyzed blood samples after the first vaccine and again two to three weeks after the booster. After the second dose, all patients had defenses against the virus’s Spike protein, but in people who had delayed the booster the antibody level detected was three and a half times higher
compared to those who received the second dose after three weeks. Research has therefore shown “how the antibody peak is strongly increased in elderly people in case of postponement of the recall to 11-12 weeks“Helen Perry, one of the leaders of the study, told the Guardian.
