“It takes about 6 weeks to make a new vaccine…everyone should be calm”
According to the British Daily Telegraph on the 3rd (local time), John Bell, a professor at Oxford Medical School, told Times Radio that “the vaccines currently developed seem to be effective against British mutations.” “I don’t know the South African mutation. I have a big question.”
Professor Bell added that the South African mutation caused significant changes in the protein structure. “(The South African mutation) appears to have increased its infectivity by enhancing the ability to bind to human cells.”
Currently developed vaccines produce antibodies against the spike protein of the Corona 19 virus. The body learns to attack different parts of the spike by itself, so even if parts of the spike are mutated, the vaccine’s efficacy will remain, but if mutations continue to emerge and the vaccine becomes difficult to recognize the spike protein, it can lead to viral infection. “The mutation does not completely neutralize the efficacy of the vaccine,” Bell said. “I think there will be a residual effect.”
“It is certainly possible to make a new vaccine in a few weeks if necessary,” Bell said. “It takes about six weeks to produce a new vaccine, so everyone has to be calm.”
