According to foreign media reports, the new coronavirus mutation that has caused severe damage around the world in recent days is called B.1.1.7. For this mutant strain, renowned researchers in the field cautioned that people still have a lot of things they don’t understand. Preliminary evidence suggests that this new mutation is more contagious than other known strains, but it doesn’t necessarily cause more severe COVID-19 cases.

This mutant virus was first observed in September last year and its characteristics include 17 different mutations, including no less than 8 spike proteins that bind to human cells. This viral component is the component that neutralizes the attack of antibodies during recovery, but after vaccination. Experts also said that the B.1.1.7 strain may still become a vaccine target.
BioNTech, as the first COVID-19 vaccine approved in Western countries, recently said that the vaccine produced and sold together with Pfizer is “very likely” to work against the new strain of the British virus.
BioNTech CEO Uğur Şahin said at a press conference on Tuesday: “We currently do not know if our vaccine can also work against this new variant, but from a scientific point of view, the immune response of this vaccine is likely may also work. Try this new variant of the virus. “
BioNTech collaborated with Pfizer to develop and produce a COVID-19 vaccine. The two companies were the first to announce positive results in phase III clinical trials in the United States. Pfizer and BioNTech have received emergency clearances in the UK and the US, and their vaccines are now ongoing in these two countries. The EU drug regulatory agency issued a similar authorization for this drug on Monday, and vaccination will soon be launched in EU countries. According to the “Guardian” report, the drug has been approved for emergency use in more than 45 countries.
Şahin said that 99% of the mutated proteins of the new British coronavirus are the same as other strains. He said that his company owns the fact that the vaccine is still effective, “we see no reason to be concerned or concerned.”
The Pfizer / BioNTech vaccine was found to be 95% effective in preventing severe COVID-19 and safe for public use. People who have been injected with this drug need a second injection every few weeks to develop full immunity. This medicine can help them fight serious illnesses, but they may still be infected with the virus. Then the neutralizing antibodies and other components of the immune system will prevent pathogens from reaching the lungs, which is where the new coronavirus is most likely to cause harm.
The scientist also noted that the vaccine can be adjusted for new variants within six weeks if necessary. Before new vaccine variants can be used, regulatory approval may be required.
British Prime Minister Boris Johnson announced on Saturday local time that due to the new epidemic, the United Kingdom will have to cancel Christmas celebrations, and governments around the world have also taken steps to reduce the risk of an outbreak of B.1.1.7. Boris claims that this mutation is 70% more infectious than the previous one, but scientists are asking for more data to clearly prove these findings.
Monitoring for new coronavirus mutations is necessary to control the epidemic and ensure that the most dangerous versions of the virus do not cause further damage. It will also help the development of vaccines.
