The first year of the pandemic was an emergency. The arrival of vaccines that might end the emergency relaxes the pressure a bit—and in the pause, problems that got submerged in last year’s chaos are now bubbling up. Even though vaccines are still scarce—in the US, most people who want a shot still can’t get one—the rich nations of the world have promised manufacturers to buy many times more doses than they need. That is threatening to choke off vaccine supply needed by the global south.

March 17: “CDC’s ‘Huge Mistake’: Did Misguided Mask Advice Drive Up COVID Death Toll for Health Workers?” by Christina Jewett, Kaiser Health News, republished in Medscape

Recent studies have determined that a basic cough produces about 20 times more particles than intubation, a procedure one doctor likened to the risk of being next to a nuclear reactor. Other new studies show that patients with covid simply talking or breathing, even in a well-ventilated room, could make workers sick in the CDC-sanctioned surgical masks. The studies suggest that the highest overall risk of infection was among the front-line workers — many of them workers of color — who spent the most time with patients earlier in their illness and in sub-par protective gear, not those working in the covid ICU.
