As the Biden Administration's booster shot roll out approaches, we have plenty of evidence that the primary COVID vaccines are still very effective, a growing number of experts say, but very little data to justify widespread use of boosters. This kind of open policy debate is exactly what we need.

Both mRNA vaccines target COVID-19’s spike, involve two doses, at least currently, and have been widely effective. That hasn’t stopped inquiring minds from wondering whether there are some head-to-head differences in the real world.

For regulatory science, from Covid-19 to environmental regulations, today’s mantra is to “follow the science.” If only we had more and better science, they exclaim, we would know the correct answers and better protect public health. But “more” and “better science” often result in the opposite effect – i.e., less protection of public health. By trying to do “perfect science,” we often get in the way of good results in the protection of public health.

Of all the organs that fail – among them the heart, lungs, and liver – treating kidney failure has produced the best results. This is due to the use of medications and dietary restrictions, but more importantly by taking over declining kidney function with dialysis and transplantation. A new study looks at the kidney availability imbalance that hinders more transplants from taking place.

The federal government has proposed a nationwide vaccine mandate. It's a terrible idea.

A group at Sloan Kettering is proposing the use of certain types of chemotherapy drugs to treat SARS-CoV-2 infection. One cannot help thinking of the old adage about what everything looks like when you only have a hammer.

"... the public in these areas are not being exposed to excessive levels of asbestos or other harmful substances … Given the scope of the tragedy from last week, I am glad to reassure the people of New York and Washington, D.C., that their air is safe to breathe, and their water is safe to drink."

Earlier this year, Sri Lanka banned imports of synthetic pesticides and fertilizers, part of its effort to embrace organic-only farming. The project has left farmers without access to vital tools and sent food prices soaring.

Storytelling in science, finding the narrative. The simultaneous rise of literacy and misogyny, heavy metal harp, the mushroom mind, and a Twitter Ivermectin thread and media bias

Public health, in much of this country, is in crisis. Hospitals are overwhelmed and understaffed, vaccination is widely resisted, state governments present mixed messages -- and COVID-19 is out of control and headed for a 4th wave. The more-contagious Delta variant has been spreading rapidly and may challenge the efficacy of our vaccines. We address this situation with population-based statistics in two modes: progression over time and geographic variation.
