It’s really something of a scientific miracle.
But with this miraculous success has come a slew of arguments. Should we be going with the most clinically efficacious vaccine that will block more transmission? What about herd immunity – which vaccine will provide us with the most protection long term?
To an extent, these discussions are important. Despite the early stage of the worldwide vaccine rollout, there is some data that certain vaccines have proven more effective in the short term against both the initial virus and its variants. If our aim is to keep Australia from having any disease outbreaks at all, as we have done so well with our Covid-19 restrictions, there’s a reasonable debate to be had about which vaccine we want to use.
