My question will be once a vaccine has been developed for a certain strain of Covid-19 virus, does this now mean that the vaccine is only effective for this strain targeted by the vaccine? IF yes, the strain of the virus needs to be identified before any treatment. Otherwise, we may need a cocktail of vaccine to have an effective treatment?
Dream on.
Look at H3N2 where vaccines been tried for 50 years and H3N2 kept mutating and mutating.
