The vaccine rollout began in December. The decline began in January.
Trump vaccines are the solution to the Chinese virus problem.
Negligible administration that doesn’t amount to much until that latter part of January due to the exponential availability. The linear death decline is tied to the initial infection rate ~2 weeks earlier in December.
There’s no way to realistically project the latent, exponential vax administration to the rapid linear decline beginning January.
Ironically as the vax rollout continues so do the “waves”.
As I’ve stated before, I haven’t seen any metrics that yet speak to vaccine success nor failure.
