So we've never created a useful epidemiology for any other virus? Because this is the only time in history we have done this ridiculous amount of testing for any virus.
Thats news to me. Asymptomatic, but infected, persons can and do spread infections to other people.
A vaccinated person, if the vaccine actually works as intended, merely has developed temporary antibodies to a specific protein (not the actual organism itself) from the targeted virus. It does not prevent that individual from becoming infected and spreading that infection to other people.
If you do not believe that a vaccinated person can become infected, please cite the biological process that would prevent any circulating pathogens from entering their body through the nose, mouth, eyes. Do you believe a virus knows who is vaccinated and who is not? Do you think a vaccine creates a magic force field that prevents the virus from entering?
Not to mention the fact that, in the case of the flu vaccine, the efficacy rate at best is between 40-50%, which means at least half of those vaccinated are still getting the flu and thus are capable of spreading it. Check out the following statistics from the CDC concerning flu vaccine efficacy:
2018-19 flu vaccine efficacy (CDC)
You are not alone in blindly accepting the nonsensical conventional wisdom that getting vaccinated protects those around you, kind of like wearing the mask. It's an effective tool to guilt you into doing something that they cannot convince you to do with provable statistical data.
Re: Epidemiology
I thought it was obvious that I was talking about COVID-19.
If you have no sample number of asymptomatic infections, how can you estimate herd immunity or case fatality rate or other useful metrics?
Re: Asymptomatic, but infected, persons can and do spread infections
Once again, I thought it was obvious that I was talking about COVID-19.
I have no idea why you wrote 5 paragraphs about vaccines and vaccinated persons.
