The first job of a vaccine is to protect vaccinated individuals from hospitalisation and death. The Covid vaccines are pretty good at that.

The second job is to limit the spread and eventually create herd immunity. The Covid vaccines are mediocre at that, not least because Covid mutates quickly. But they do lower the r value, which is a win, even if they don't reduce it to zero.

Vaccination is a collective issue. No question.

The fact that the far right has weaponised vaccination hesitancy, with the result that devotees are filling up hospitals and dying - often pleading for vaccination when it's too late - should also be a clue.
