A British minister said that there are about 4,000 variants of the virus that cause COVID-19 worldwide, so now all vaccine manufacturers, including Pfizer Inc and AstraZeneca Plc, are trying to improve their vaccines.
Thousands of types of coronaviruses that cause COVID-19 have been documented as virus mutations, including so-called British, South African, and Brazilian variants that spread more quickly than others.
“It is very unlikely that the existing vaccine can be effectively applied to Kent or other variants,” vaccine deployment minister Nadim Zahavi told Sky News.
“All the manufacturers, Pfizer-Bayonet, Modern, Oxford-AstraAnica and others are looking at how they can improve their vaccine to make sure we are ready for any form – of COVID’s worldwide There are 4,000 variants. ”
According to the British Medical Journal, thousands of variants are generated, as viruses are mutated upon replication, with only a very small minority being important and likely to replace the virus in a plausible manner.
“We have the largest genome sequencing industry – we have about 50% of the world’s genome sequencing industry – and we’re keeping a library of all the variants so we’re ready to respond – whether it’s in the autumn or from Further – any challenge that the virus may present and cause the next vaccine.
According to Johns Hopkins University of Medicine, the novel coronavirus – known by scientists as SARS-CoV-2, killed 2.268 million people in China in late 2019.
