40% to 50% of Covid deaths involve pneumonia.
Instead of mass vaccinations with experimental drugs, we should mass vaccinate the elderly and the infirm with pneumonia vaccines, which have been extensively tested.

This post-mortem needs to be looked at as a crime scene, not just a “what can we do better next time.”
