Vaccination against SARS-CoV-2 lowers the risk of long COVID after infection by only about 15%, according to a study of more than 13 million people. That’s the largest cohort that has yet been used to examine how much vaccines protect against the condition, but it is unlikely to end the uncertainty.

Diabetes risk rises after COVID, massive study finds
People who get COVID-19 have a greater risk of developing diabetes up to a year later, even after a mild SARS-CoV-2 infection, compared with those who never had the disease, a massive study of almost 200,000 people shows.

Even Mild COVID Can Increase the Risk of Heart Problems
Overall, the risk of any heart complication over the course of one year was 63 percent higher in people who had gotten COVID compared with those in the contemporary control group. At the end of a year, there were 45 additional cardiovascular events—such as stroke or heart failure—per 1,000 people among those who tested positive for COVID.

COVID-19 has caused the biggest decrease in life expectancy since World War II
The COVID-19 pandemic triggered life expectancy losses not seen since World War II in Western Europe and exceeded those observed around the dissolution of the Eastern Bloc in central and Eastern European countries, according to research published today, led by scientists at Oxford’s Leverhulme Centre for Demographic Science.

Wildfire smoke may have contributed to thousands of extra COVID-19 cases and deaths in western U.S. in 2020
Thousands of COVID-19 cases and deaths in California, Oregon, and Washington between March and December 2020 may be attributable to increases in fine particulate air pollution (PM2.5) from wildfire smoke, according to a new study co-authored by researchers at Harvard T.H. Chan School of Public Health.

Upgrading PPE for staff working on COVID-19 wards cut hospital-acquired infections dramatically
“Once FFP3 respirators were introduced, the number of cases attributed to exposure on COVID-19 wards dropped dramatically – in fact, our model suggests that FFP3 respirators may have cut ward-based infection to zero.”

New research examines wastewater to detect community spread of Covid-19
A series of crucial setbacks in Covid-19 testing has made it difficult to keep up with the virus’ rapid spread, and has inspired some researchers to look to wastewater to help fill in the gap of measuring how prevalent SARS-CoV-2 is in a given community.
In a paper posted Tuesday to the preprint server medRxiv, researchers collected samples in late March from a wastewater treatment plant serving a large metropolitan area in Massachusetts and found that the amount of SARS-CoV-2 particles in the sewage samples indicated a far higher number of people likely infected with Covid-19 than the reported cases in that area.
