I think those unvaccinated deaths are still mainly in the elderly. The vaccine uptake in the elderly is lower in the US than here.
Nope. It's more by state than age in the US. Both re vaccination uptake, and unvaccinated deaths. Is one vaccine type less effective than another at preventing deaths?
Data from USA (and Israel and Norway) is majority of deaths (whatever age) are in the unvaccinated. Fully vaccinated are getting breakthrough infection but rarely needing hospital.
I think it would be helpful to have a vaccine breakdown (AZ, Pfizer, Moderna) for the UK fully vaccinated deaths.
