Public health is about all health outcomes, not just a single disease like Covid-19. It is important to also consider harms from public health measures.
“As an infectious-disease epidemiologist, I had no choice. I had to speak up. If not, why be a scientist? Many others who bravely spoke could comfortably have stayed silent. If they had, more schools would still be closed, and the collateral public-health damage would have been greater.” ~ Martin Kulldorff
“The question is not whether to aim for herd immunity as a strategy, because we will all eventually get there. The question is how to minimise casualties until we get there. Since Covid-19 mortality varies greatly by age, this can only be accomplished through age-specific countermeasures.” ~ Martin Kulldorff
