Studying the genomes of modern humans from 26 worldwide populations, researchers discovered the genetic “footprint” of an ancient coronavirus outbreak. Studies like this one could help identify viruses that have caused epidemics in the distant past and may do so in the future. A new study co-authored by a University of Arizona researcher has discovered a coronavirus epidemic broke out in […]

COVID-19 Antibody Study Shows Downside of Not Receiving Second Shot A new study shows that two months after the second Pfizer/Moderna vaccination, antibody response decreases 20% in adults with prior cases of COVID-19. The study also tests how well current vaccines resist emerging variants. The Northwestern University study underscores the importance of receiving a second dose of vaccine, not only because it is […]

The Delta variant is more contagious than original SARS-CoV-2 and better able to escape prior immunity, according to modeling studies of coronavirus variants. Researchers at Columbia University Mailman School of Public Health used a computer model to estimate that the Delta variant is around 60 percent more contagious than the original SARS-CoV-2 virus and can escape immunity from prior infection roughly half of the […]

Study compares risk of blood clotting problems after covid-19 infection and vaccination The risk of blood clotting problems is much higher after covid-19 infection than after receiving a covid-19 vaccine, according to research from the University of Oxford. The study, published in the British Medical Journal, looked at more than 29 million people aged 16 or older who had a first dose […]

The recent surge in COVID-19 Delta variantTrusted Source cases in the United States is mostly affecting unvaccinated populations. The authors of the new article point out that U.S. states with more than 70% of their population vaccinated report lower numbers of vaccine breakthrough cases, hospitalizations, and deaths from COVID-19. Given the high transmission rate of the Delta variant, reaching herd immunity and interrupting transmission […]
