Covid-19 Vaccines or Infections: Which Carries the Stronger Immunity?

Evidence is building that immunity from Covid-19 infection is at least as strong as that from vaccination. Scientists are divided on the implications for vaccine policy.

The role of immunity from infection, which scientists have been trying to figure out since the outset of the pandemic, has gained fresh significance amid the controversy over vaccine mandates.

Vaccines typically give rise to a stronger antibody response than infection, which might make them better at fending off the virus in the short term. Infection triggers a response that evolves over time, possibly making it more robust in the long term. A combination of both types appears to be stronger than either alone. But the jury is out on whether one form is stronger than the other, and whether their relative strength even matters for vaccine policy.
