> There are those trying to publicly undermine the necessity and success of vaccinations. If we allow the defences of those who did the right thing and got vaccinated early to wane, just when new waves of infection are on the rise, we will not only be exposing them to danger, but providing fodder for the anti-vaxxers and conspiracy theorists. That is why it remains crucial that countries that had early and efficient vaccine roll-outs are able to deploy boosters, so the vaccines can both continue to work and be seen to be working.
