And for OP, your post is SO scientifically innacurate because there are no studies that shows that getting vaccinated increases your chance of catching the flu (or any other virus in this manner) so you may want to support your claim with some studies (if you could find any) otherwise it wont be taken seriously.
There won't be any studies released soon enough to help people who are facing a pandemic right now.
Anyway, do you know of any viruses that have an incubation period that varies from 3 days to 14 days? I'd like to exclude previous SARS coronaviruses since that's really the same thing as this.
