No difference in hospitalizations from COVID between the vaccinated and unvaccinated, if..
A quick examination of this figure from the CDC data released on January 20 (Link) shows that there is virtually no difference in hospitalizations from COVID between the vaccinated and unvaccinated, if a prior COVID infection took place.
This simple table, based on data from nearly 22 million COVID positive cases in California between May and November 2021, makes 2 points so abundantly clear, it’s hard for me understand how there can be any vestigial ambiguity:
- Vaccines unquestionably reduce the risk of hospitalization in previously uninfected people.
- In people who are previously infected vaccines offer zero additional benefit with respect to hospitalization.
Can the case be any clearer, simultaneously, for both the efficacy of vaccines and natural immunity?
