The study looked at COVID-19 cases and hospitalizations in California and New York between May and November of 2021, determining that numbers were highest among unvaccinated people who hadn’t been previously diagnosed with the virus. Prior to delta becoming the predominant variant in June, cases were higher among people who had COVID before than those who were vaccinated alone, the study said. During the week of May 30, compared with case rates of unvaccinated people without a previous diagnosis, the study said case rates were 19.9 times lower for vaccinat...

Neurological symptoms have been commonly reported in those suffering from post-COVID conditions - lingering symptoms experienced four or more weeks after an initial infection. But a new study by researchers at Yale University found even those who contract mild infections can sustain neurological damage. In an interview with NBC Connecticut, Dr. Akiko Iwasaki, who conducted the study, explained researchers intentionally gave mice a mild respiratory infection with SARS-CoV-2, the virus that causes COVID-19. Over the course of seven days, they examined the infection's impact on the brain. "And what we found is that even with a very mild infection, which we really cannot measure any disease phenotype in these mice, we still saw some significant damage in the c...

Booster shots of the Pfizer-BioNTech and Moderna vaccines aren’t just preventing infections with the highly contagious Omicron variant — they’re also keeping infected Americans from ending up in the hospital, according to data published on Friday by the Centers for Disease Control and Prevention. The extra doses are 90 percent effective against hospitalization with the variant, the agency reported.

The extra doses were most effective against infection and death among Americans aged 50 and older, the data showed. Over all, the new data show that the vaccines were more protective against the Delta variant than against Omicron, which lab studies have found is partially able to sidestep the...
