One and done? Why a universal vaccine that covers us for all future COVID-19 variants could be around the corner
ABCRemember whack-a-mole, the arcade game where a plastic mole pops its head up and you whack it with a mallet? Key points: Scientists are working on a universal vaccine that could guard against existing and future COVID-19 variants Their vaccine has been successful in animal trials The main barrier to proceeding to human trials is funding It's a game scientists are comparing to the fight against COVID-19: No sooner has one mole, or variant, been whacked by vaccines than another appears. So, when will we get ahead of the virus and how far away are we from having a universal vaccine, one that will target all past and future COVID-19 variants and sub-variants? "One of the main avenues of research that we've been actively exploring over the last year and a half or so, next-generation, broad-sweep, universal vaccines that could not only deal with existing SARS-CoV-2 variants, but could perhaps ward off a future emergence event of a coronavirus," Dr Martinez told the ABC News Daily podcast. "What we've actually demonstrated by one of our vaccine concepts is a vaccine that could not only protect against SARS-CoV-2 and its variants — at least even against Omicron, that we've tested and shown efficacy against — but also against the original SARS."
