What Can We Expect From a COVID-19 Vaccine?

As I write this, there are 42 COVID-19 vaccines in various stages of human trials. Eleven of these are in large, late-stage trials. More than 100 others are under development. Certainly within the next year, we are likely to have the first of possibly many COVID-19 vaccines ready for deployment.

There are many things that are still unknown about that first vaccine, but this we know for sure: However effective it will be at protecting younger adults, it will be less effective at protecting more vulnerable older adults.

Vaccines are one of the great achievements of science. They have saved hundreds of millions of lives and led to the eradication of one human disease (smallpox) and the near-eradication of another (polio). Yet no vaccine is perfect. That is, no vaccine is 100% effective, 100% safe and lasts for life.
