You can chose evidence based science and medicine or policy based science and medicine. You have both for very long because they will be at odds with one another. In the 1980s the gay homosexual community and the government opted for a policy based science and medicine in their approach towards AIDS. One result of that decision (among many) was the prohibition of contact tracing by the public services as at that time it was deemed to be too insensitive or stigmatizing to be identified as being HIV positive. Safe sex was championed as the answer. If strict time tested public health measures had been followed at the outset of the epidemic the disease could been contained or even eliminated, but politics prevailed. As a result a holocaust was unleashed. Millions died. We have learned little from that time. Fauci was in charge of our response then as he still is today. Yet you wonder why more hasn't been done.
