I know there are colossal epidemiological and biochemical differences, but I would observe that twenty years ago another virus, HIV, had an almost 100% fatality rate. Now, managed with a relatively cheap daily anti-retroviral medication, most HIV patients lead long and healthy lives, and are mostly/largely non-infectious. There is still no vaccine for HIV.
Don't shout at me - I know they are totally different beasts. But HIV medication shows that medical science can come up with a compound that drastically reduces the impact of a virus.
Vaccination, treatment, acquired immunity - they all play their part.
