@hildabast @PLOS I'm proudly descended from two generations of vaccinationists: my grandfather helped bring TB vaccination to Australia, getting on for a century ago...
These vaccines are marvels, but the game changer would be a sterilizing vaccine against COVID, may it come soon! The durable vaccines are a step in that direction...
Of course, the real threat is wilful ignorance, and there will never be a vaccine against that.
