so answer this
in a pandemic where many people died

HOW WOULD YOU DESIGN A PLACEBO BASED PREVENTION TRIAL

It would never get through ethics

a group of participants not suffering covid are told
no vaccines
no masks
no hand sanitation

for how long do you ask them to be in the community with NORMAL level of SARS-CoV-2. Which country is normal to undertake the prevention study over what time period?

Is it ethical to have the placebo taking no precautions at all?


come on @Teddyward are you able to answer..?

the study of humanized mouse genome referenced in the footer of Scripp Research Institute https://www.scripps.edu/gallay/sars-cov-2.html comes to this conclusion and that is probably as good as you could get for prevention in vivo
