New vaccine rollout off to slow start: About 12 million Americans have received the new shots since mid-September, less than 4% of the U.S. There have been numerous reports about supply issues and difficulty accessing the new shots across the country. As of mid-October, many community health centers were still waiting on supplies to arrive. Pharmacies and nursing homes have also faced difficulties in stocking enough vaccines amid bumps in a new distribution model, which changed from federal entities to wholesalers and other private suppliers.

A new long COVID-19 theory: Remnants of the virus that causes COVID-19 may linger in the gut, ultimately causing a reduction in circulating levels of serotonin. According to new research from scientists at University of Pennsylvania in Philadelphia, this may explain a number of long COVID-19 symptoms, such as brain fog and memory problems. The findings are believed to connect many of the major hypotheses surrounding the causes of new or persistent symptoms, such as lingering virus components, inflammation and increased blood clotting.
