efficacies

For the next pandemic, if we have certain vaccines with starting efficacies, we can predict the minimum proportion we need to vaccinate to achieve vaccine-induced herd immunity.

If you don’t typically overanalyze the efficacies of the medications that doctors recommend, there’s no reason for you to do so when it comes to the COVID-19 vaccines, she said.

For young kids, there are now two vaccines available with very similar mechanisms but different doses, dosing intervals and efficacies.

But mRNA-based vaccines can be manufactured very quickly, and so far often have higher efficacies.

Still, the vaccines, shown in clinical trials to have efficacies of up to 95% against symptomatic disease, have finally given the world the prospect of an escape from COVID-19’s long siege.
