THURSDAY, Sept. 2, 2021 (HealthDay News) -- A new study of more than 19,000 San Diego health care workers finds that COVID-19 vaccination may have lost some of its power to ward off "breakthrough" infections.But that's no reason to lose faith in the vaccines: In the study, the rate of COVID-19 infection in July among unvaccinated workers was nearly triple that of people who had gotten their shots.Still, the study found a "dramatic change in vaccine effectiveness between June and July," according to researchers led by Dr. Francesca Torriani, of University of California San Diego (UCSD) Health. Her team calculated that "vaccine effectiveness exceeded 90% from March through June, but fell to 65.5% in July."In June, one-third of diagnosed cases of COVID-19 occurred among fully vaccinated...

THURSDAY, Sept. 2, 2021 (HealthDay News) -- If you're vaccinated against COVID-19, you may still get infected -- but the odds you'll need hospitalization are reduced by about two-thirds compared to unvaccinated people, a new study reveals.Vaccination also greatly increases the chances that COVID-19 infection will be asymptomatic and halves the risk of long-haul symptoms -- those lasting 28 days or more, researchers report in The Lancet Infectious Diseases journal."We are at a critical point in the pandemic as we see cases rising worldwide due to the Delta variant. Breakthrough infections are expected and don't diminish the fact that these vaccines are doing exactly what they were designed to do -- save lives and prevent serious illness," said co-author Claire Steves, of King's College...

THURSDAY, Sept. 2, 2021 (HealthDay News) -- If you feel exhausted after a day filled with online meetings, well, you are not imagining it.A new study found that the pressure of having the camera on for a long time is draining. This so-called "Zoom fatigue" is even worse if you're a woman or a new employee."There's always this assumption that if you have your camera on during meetings, you are going to be more engaged," said Allison Gabriel, the McClelland Professor of Management and Organizations and University Distinguished Scholar in the University of Arizona's Eller College of Management. "But there's also a lot of self-presentation pressure associated with being on camera," she said in a university news release. "Having a professional background and looking ready, or keeping...
