At the moment, the expectation of efficacy is very low. Something like 50% effective rather than 98% effective.I'm of the opinion that at least 3 different vaccines should be adminstered to ensure that the virus populations do not evolve to counter the vaccines.Well, we don't have 1 vaccine yet, and it would seem unwise to wait for development of 2 more which may never exist.
We didn't need to do it with polio or smallpox.
And there's no direct interaction between the virus and the vaccine, so "resistance" of the sort that applies to bacteria isn't an issue.
By combining different vaccines, I expect the mixed vaccine would be more effective, as well as making adaptive evolution against the vaccines far more difficult for the virus.
