But imagine if the next Covid vaccine jab you have were the last you would ever need. That’s a dream being actively pursued now by researchers, who feel it could be possible to make a “universal” vaccine against the Sars-CoV-2 virus that would work well not only against all existing variants but any that the virus could plausibly mutate into in the future.
