Here are some recent studies on COVID-19, including research pending further study and peer review.
The following is a summary of some recent studies on COVID-19. They include research that warrants further study to corroborate the findings and that has yet to be certified by peer review.Fully vaccinated individuals who get infected with the coronavirus spread the infection to fewer people and are contagious for less time compared to people who are partially vaccinated or unvaccinated, a small study from South Korea suggests.
When the Delta variant of the coronavirus was predominant in the UK, researchers tracked 377,194 individuals with cancer and more than 28 million people without malignancies. After two doses of a COVID-19 vaccine from Pfizer PFE.N/BioNTech 22UAy.DE or AstraZeneca AZN.L, overall vaccine effectiveness against infection was 69.8% in the general population and only slightly lower, at 65.5%, for cancer patients, the researchers reported on.
