Have you found a study yet where someone with a vaccine plus two weeks has ended up in hospital? I haven't.
There is no possible way that any of vaccines can give you covid. That is complete fear mongering garbage. There is no virus in them. Not even deactivated virus.
Could it make you more susceptible in the window between vaccination and two weeks out? I don't know. I'd be inclined to believe no but don't have enough information either way.
People need to stop thinking of covid as a single disease. The variants are wildly different in their ease of transmission, populations that get sick and impact on those populations. It is a race between vaccinations and variants. Now, some countries (typically poor countries) are not vaccinating much at all. We may be able to look back and see how that worked out. I doubt those countries have the resources for accurate real-time reporting.
the only experience I have to speak to this is I have 2 employees who are terrified and haven’t left home in a year for anything. They went and got vaccinated last week and both ended up in hospital with COVID a few days later.
If I had to guess I would assume that vaccination sites are ripe with COVID and people let their guard down thinking it’s a safe clean medical environment . Maybe what is also fueling spread are people who wouldn’t normally gather in groups are doing so to get the vaccine and getting it there due to feeling safe in a supposed medical environment. Or ignorance of vaccines is making people think they are protected immediately and fully after one shot?
