How long until it's all over?

We can't say for sure, but everything depends on how many people agree to be vaccinated.

Who should be vaccinated first?

Modelling shows that old and vulnerable people should be prioritised.

How were the vaccines tested?

Like any medical drug, vaccines are tested in large-scale randomised controlled trials.

How effective are the vaccines — and how do we know this?

The efficacy of vaccines is estimated from trials, using statistical techniques.

Since herd immunity will protect us all, why do I need to get vaccinated?

Because the vaccine may not stop transmission of the virus.
