Everything changed a while ago when we heard about the British strain of the coronavirus, which is likely to be more contagious. And since it appeared after the vaccination process had begun, questions arose as to whether the vaccine was prepared for it. Scientists, of course, immediately started carrying out the relevant research and, as the conclusions have just published, show no cause for concern, because the Pfizer and BioNTech vaccine is effective against 16 different mutations of the coronavirus, including “British”. According to Reuters, the vaccine does not need to be modified in order to counteract a virus that appears to be more contagious than others, according to a study by researchers at Pfizer and the University of Texas.
This one was called B117 and although it appeared in Great Britain, it is now also found elsewhere in the world, such as the United States, among people who have not traveled to the UK, so its prevalence is only a matter of time. It is worth remembering, however, that there is currently no evidence that it is more dangerous than previous strains, and we have confirmation that the vaccine is just as effective against it: – We tested 16 different mutations and none of them have a significant impact on the virus. This is good news. Of course, this does not mean that 5pm will not have either, explains one of Pfizer’s scientists, Phil Dormitzer.
Is this last indication just theorizing, or is it pointing to another mutation that has gotten loud recently, namely the one in South Africa? It is hard to say, especially since local scientists suggested that this could be more problematic, but we will find out about it all in a few weeks: ‘This is only a theoretical concern, but it is justified that the South African variant may be more resilient,’ Professor Shabir Madhi said at the time in a speech for BBC. At the same time, however, he pointed out that theoretically we are dealing with a different virus than the one in Great Britain, but at the same time, both have the same N501Y mutation, which is most likely responsible for the increased transmission rate, so the vaccine may be able to cope with this strain without any modifications. Time will tell.
