Of course....but then it mutates. And we are vaccinated against a now mostly extinct SARS virus.
Similar to every flu season.
Unlike MMR, we are fighting against an ever changing virus. We can't very well shut down the entire world every time we run into a virus that has a mortality rate of .13%.
The season flu vaccine still confers therapeutic benefits to people who contract the flu. Combined with anti-viral medications administered within 48 hours of the onset of symptoms, the effects of the flu are marginal.
It is not just about having a functional vaccine, it is having a vaccine and treatments.
