I encourage everyone eligible to protect themselves by getting vaccinated, but the current thinking is that new variants are most likely to evolve in immunocompromised patients who experience prolonged infections. The vaccines aren't very effective for them.

It's also possible for new variants to evolve in animal hosts, then spread back to humans.

The vaccines would (probably) have been effective on whoever gave the immunocompromised patient the disease, though.

It's not all about the individual.

Unfortunately there will be no significant herd immunity effect to protect the immunocompromised. They will all be exposed.

The main benefit of vaccines is in reducing symptom severity. They only produce a limited and temporary reduction in transmission risk.
