Test prudently
By Vincent Racaniello | | Basic virology
by Amy B. Rosenfeld I do not advocate testing for any person vaccinated against SARS-CoV-2 unless they display severe symptoms or live with those who for whom vaccines are not yet approved.

By David Tuller, DrPH I recently posted a blog about the protocol for a Canadian Long COVID exercise trial in which the investigators proposed lying to the participants about the nature of both the study and the intervention being assessed.
