Does the first dose of the Moderna/Pfizer vaccine provide any level of immunity, or are we unlikely to see any results of reduced infection rates until a month after someone gets the vaccine?
For instance, the USA has injected over 2% of people now. Let's assume these people all will have gotten their second dose by the end of January, and that the antibody response is functional in all of them. Is that the point at which the death rate could start being reduced, especially if that 2% was targeted at people living in nursing homes who make up almost 40% of deaths?
