They have reported those that were fully vax'd (both shots, more than 2 weeks) and showed there were "break through" cases that still got sick. That was a relatively low number. Not sure if they are fully reporting the positive cases that are only partially vax'd (ie only one shot). The theory is a person is more susceptible during that phase before 14 days after shot 2. Just a theory though.
If it’s somebody’s theory, it’s a half baked one.
There’s good evidence that first shots are in the range of 70% effective after 2 or 3 weeks, so why would one expect a period of increased susceptibility after the second shot and then suddenly, two weeks after you get it, bam!...you’re fully vaccinated and have maximum protection.
This T cell-mediated immune response is even more important as studies on humoral immunity to SARS-CoV-1 provided evidence that antibody responses are short-lived and can even cause or aggravate virus-associated lung pathology
Compared with the two-dose regimen, a single shot triggers a weaker immune response and may leave recipients more susceptible to dangerous virus variants.
