> It was more of a 50% reduction No, it's better than you think. According to my favourite immunologist, Iceland reports vaccine effectiveness of 60% against ANY infection and 90% against severe disease.

It's worth remembering, also, that vaccination reduces transmission, in turn reducing severe cases.

The reduction in transmission rates is smaller than you'd think. At 3 months the reduction has diminished substantially, 58% transmission risk, marginally better than 67% for unvaccinated people. There is no data yet for 6 months, 1 year, 5 years. https://www.nature.com/articles/d41586-021-02689-y https://www.nature.com/articles/d41586-021-02689-y https://www.medrxiv.org/content/10.1101/2021.09.28.21264260v1 https://www.medrxiv.org/content/10.1101/2021.09.28.21264260v...

  Erm, I was explicitly talking about reduction in hospitalisation and death, not of transmission (from infected people). Those are separate aspects of vaccine peotection.
