Which COVID-19 vaccine is the best?

The internet seems to know exactly which vaccines are the best - and the worst.

But you can't compare vaccines that easily. And doing so might even be harmful in a pandemic. We tend to look at efficacy rates. Because they measure how likely you are to get COVID-19 after you’ve been vaccinated. The problem is that these numbers were not created equal. Instead they are determined by when and where the efficacy trials took place and who was included. So how do you determine which vaccine is best for you?
