Fact check: Do COVID vaccines protect against the delta variant?
...
None of the vaccinations that have been approved so far provide 100% protection against a coronavirus infection — studies have shown that since their introduction. Vaccinated people, particularly those with preexisting illnesses, still run the low risk of becoming infected — and in the worst case, dying. However, the current death rate in the UK remains low, despite rising infection rates.
One of Germany's leading virologists, Christian Drosten, said in a Coronavirus Update podcast in June that there were "cases where people who are double-vaccinated also die." He suggested that experts look carefully at the exact cause of death and how the diagnosis was made.
The high proportion of vaccinated individuals among the dead is probably due to the fact that about half of the population is now fully immunized, combined with the fact that numbers of overall deaths are dropping. Moreover, according to PHE's data, 116 of the 118 people who died were over the age of 50.
Peggy Riese, a scientist at the Helmholtz Center for Infection Research (HZI), explained the scenario with the help of a concrete example. "If 100% of a population is vaccinated, then a few people who are vaccinated also die," she told DW. She said that doesn't mean the vaccine isn't safe, just that it doesn't provide 100% protection.
Additionally, low numbers of vaccinated individuals could die if their inoculations lacked efficacy due to the presence of immunosuppressants, for instance, in those who have had transplants, as Georg Behrens, a professor at the Hanover Medical School's clinic for rheumatology and immunology, recently told DW.

So long as Covid circulates among the unvaccinated, a small percentage of the vaccinated population will contract Covid and some will die, particularly the vulnerable.
