Vaccines are a way out, but sadly it’s not a case of one jab and 100% immunity. This will become a rolling programme, much like the annual flu vaccine.
The virus will continue to mutate, like flu. However, the vaccines, now developed and tested can be simply tweaked rather than completely redeveloped. Again, much like with flu and the flu vaccine. According to the Guardian the Pfizer vaccine is simple to tweak, the AZ one takes a bit longer, although they already have plans to incorporate the new strains into second vaccines due to be given later this year.
Coronavirus mutates at a much higher rate than large and complex viruses like chickenpox (which has in the region of 125,000 base pairs in its genome), but slower than flu (around 13,000 base pairs). According to a google search the SARS-CoV-2’s genome has around 30,000 base pairs and is thought to accumulate approximately one to two mutations a month. So it will probably be a bit like the annual flu vaccine, where it get tweaked to protect against the variants expected each winter. Remember, the flu vaccine typically only achieves around 50% effectiveness but because enough people have it, flu is kept to manageable levels.
There are two other ways of managing the virus, outside of lockdowns and social restrictions: treatments and public health capacity.
Sadly, I don’t hold out much hope for a sudden and massive increase in public health capacity.
However, a number of drugs are being tested to help people recover from covid better and quicker. BBC article here
Yes, it’s spectacularly shit at the moment - much more for some than others - but there IS light at the end of the tunnel.
