New studies have suggested that antibodies created by some of the COVID-19 vaccines may be less effective to neutralize new variant of coronavirus. Most of the novel coronavirus with new variant have been reported in UK, South Africa and Brazil. Journal called Cell has published these studies. On the occasion, coronavirus vaccine from Pfizer and Moderna have been tested against the variants that have been found in UK, Brazil and South Africa.
In case there is a change in the virus shape as the antibody latch on to it then antibodies may not able to recognize the virus and neutralize it.
During the time, a comparison has been made regarding effectiveness of antibodies between old virus and new variant of coronavirus.
Strains from Brazil and Japan have shown five to seven times more resistance in comparison original novel coronavirus that has been originated from Wuhan in China.
One of authors of the study has explained “In particular we found that mutations in a specific part of the spike protein called the receptor-binding domain were more likely to help the virus resist the neutralizing antibodies”
However, resistance of the virus to the new variant of coronavirus does not mean that it is not effective at all. Scientists have said, “The body has other methods of immune protection besides antibodies. Our findings don’t necessarily mean that vaccines won’t prevent COVID, only that the antibody portion of the immune response may have trouble recognizing some of these new variants.”
Now, it has become essential to know which variant of the virus may able to evade the immune factor of the vaccine completely.
So, we expect to get a vaccine against coronavirus in the future that is able to neutralize the coronavirus regardless of its variant.
