I wonder if a V2 of the vaccine with multiple independent targets is where we'll end up? Right now, covid is winning the math-war, with more mutation at-bats on average than it needs to hit a home run with its batting average. Say the chance of any one area of attack being evaded is 1%. If successful variant candidates must hit two simultaneous mutations, now it is 0.01%. Throw in a third at 0.0001%. At a certain point, it would seem like you can make the math unfavorable to the virus, especially if your targets are against these more optimized strains--in order to mutate, it might be stuck with less-optimized mutations to get off the local maxima. Anyone know the status of any multi-valent vaccines?
