You have yet to tell us why you are qualified to conclude this or many other things you post.
An appeal to expertise is irrelevant. On a skeptic site we should look at the argument not who makes it. Whether I have a degree in medicine and did research in virology and infectious disease transmission is irrelevant to whether the case I make is evidence based. When you fairly criticise my argument that is justified, but it has to based on the evidence.
When I say that someone who voices an opinion based on being 'an associate Professor of Epidemiology' with no background in health policy, communicable disease control, or modelling of infectious disease, is less qualified than me to comment, it just means that his opinion should be justified not accepted because he works at an US university instead of what used to be called a large clap clinic with a small hospital attached (which is where he started).
