Given the available vaccines why bother?

Post by admin »

The current vaccines have proven effectiveness against the strains of Covid-19 which were dominant in the UK last year. It is known that vaccine resistant strains exist such as those commonly known as the South African variant and the Brazilian variant. There are plans to produce new vaccines for new strains but this can only occur after the strains have emerged.

Some people cant take the vaccines and the vaccine efficacy reduces with time so that around 6 months after vaccination only around 50% of people have immunity. Some drugs already exist but these mainly help with very serious illness when the patient is already in hospital rather than medication which can be taken in the community.
