“A handful of studies are already reporting that the new strains are more than 50% more contagious than the wild-type Wuhan SARS-CoV-2 virus and the approved vaccines may not be as effective against these strains and warrant further studies to confirm the efficacy of the current vaccines. It is un-avoidable that new vaccines will need to be developed to complement or replace the current vaccines and included as a cocktail with the current vaccines. Attacking several sites at once using a cocktail significantly reduces the chances of coronavirus escaping the immune system, making therapy very effective. The development of vaccines using more conserved protein with a low chance of mutation could be another strategy to overcome this emerging issue.”
