Even as the coronavirus continues to spread throughout the U.S., this week saw some good news on the vaccine front, with pharmaceutical giant AstraZeneca reporting results from a trial of its COVID-19 vaccine. But the announcement was somewhat confusing in that the effectiveness varied substantially based on the dosage. Scientist Sanjay Mishra from Vanderbilt Medical Center, who himself is doing vaccine research, explains the key advantages of this Oxford-AstraZeneca vaccine and what we do and do not know from the limited data available. To learn more about the other front-runner vaccines from Pfizer and Moderna, I recommend this article on mRNA vaccines and another on why safety has not been compromised in the U.S.’s Operation Warp Speed program.
As you get together this week with family or friends – whether it’s in person or virtually – this piece on the science of laughter is worth a read. It turns out having a few chuckles isn’t just a relief in the moment; feelings associated with laughing build resilience and enhance creative thinking.
Researchers from the University of Arizona report on how they monitored sewage to effectively isolate cases on campus and help keep the spread under control. They argue that this technique has lots of potential, not just for municipalities but for a host of other locations, such as offices parks, factories and military bases.
And finally, with Thanksgiving tomorrow and winter holidays coming up, here’s a special newsletter that compiles the latest science-based recommendations on getting together with others during this pandemic in the safest ways possible.
Have a happy and safe Thanksgiving.

As viruses are transmitted from person to person they are constantly mutating and replicating. Could the SARS-CoV-2 virus evolve to evade the new vaccines that have just been developed?

COVID-19 cases are skyrocketing across the US. Testing has ramped up over the past few months, but increasing hospitalizations, deaths and test-positivity rates show that the virus is out of control.
