In China, the effect of mutations on the effectiveness of COVID-19 vaccines was assessed

The mutations of the coronavirus that he has undergone to date will not affect the effectiveness of the vaccines being developed against him. Such a statement was made today, September 25, at a press conference by the head of the Center for Biotechnology of the Ministry of Science and Technology of China Zhang Xinmin. By now, we have not seen serious mutations of a new type of coronavirus, he emphasized. According to him, in the global database of COVID-19 there are already more than 100 thousand sequences of the coronavirus genome. However, a comparison of more than half of them showed that there are large similarities between them. Follow the development of events in the broadcast: Coronavirus in the world: countries in search of a vaccine - all the news See also: Scientists in the United States have identified a more contagious strain of coronavirus. The level of similarity, if we talk about nucleotide sequences, is more than 91.3%, TASS quotes Sinmina. This suggests that mutations occur within the norm. Also, according to him, the S-protein, on which the work on the development of the vaccine is mainly focused, remains generally stable. Therefore, if vaccines tested to date are launched into production, they will be able to successfully fight all sequences of coronavirus, the head of the center emphasized. Also on the topic: In Singapore, a vaccine is created that can be changed with a coronavirus mutation. As reported by the news agency, scientists in Houston, based on the results of a study of more than 5 thousand coronavirus genomes discovered during the first and second wave of the epidemic, concluded that the coronavirus continues to mutate from the beginning of its appearance. At the same time, one of these mutations could make it more contagious. We add that specialists in Singapore are working on the creation of a universal vaccine against COVID-19, which can be modified within three weeks in the event of a coronavirus mutation.
