During the first 6 months of the US COVID-19 vaccination campaign, most adverse events reported to surveillance systems were mild and short-lived, researchers from the Centers for Disease Control and Prevention reported in The Lancet Infectious Diseases. The study examined safety data collected through the new v-safe surveillance system and the Vaccine Adverse […]
Measures to reduce transmission of SARS-CoV-2 have also been effective in reducing the transmission of other endemic respiratory viruses. As many countries decrease the use of such measures, we expect that SARS-CoV-2 will circulate with other respiratory viruses, increasing the probability of co-infections. The clinical outcome of respiratory viral co-infections […]
The human body needs a lot of oxygen: about a cup a minute, just to stay alive. If we can’t get the amount we need because of injury or disease, like COVID-19, our bodies quickly start to suffer from oxygen deprivation. After just a few minutes, abnormally low oxygen levels […]
A new omicron subvariant of the virus that causes COVID-19, BA.2, is quickly becoming the predominant source of infections amid rising cases around the world. Immunologists Prakash Nagarkatti and Mitzi Nagarkatti of the University of South Carolina explain what makes it different from previous variants, whether there will be another […]

COVID-19 patients who are successfully weaned off a ventilator may take days, or even weeks, to regain consciousness, especially those who experienced episodes of hypoxemia while intubated, a new study shows. “As we started to see the first patients waking up after successful COVID-19 ICU treatments, we also encountered many […]
The Omicron variant of SARS-CoV-2 is associated with significantly lower risks of hospitalisation and mortality compared with the Delta variant, according to the largest study to date to directly compare outcomes. Researchers in a multicentre UK team led by Imperial College London, the MRC Biostatistics Unit at the University of […]
Adult pneumococcal vaccine recommendations have been considered some of the most complicated vaccine recommendations to appropriately implement. The good news: Implementation just got simpler. With two newly licensed pneumococcal conjugate vaccines (PCVs) on the market, the Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices (ACIP) aimed […]
Vaccines are the best way to protect yourself against COVID-19. They elicit a strong defense against SARS-CoV-2, the virus that causes the disease. Vaccines activate your body’s disease defense system, called the immune system. The response starts by engaging two kinds of immune cells: B cells, which produce antibodies that […]
As much of the country prepares to ditch their masks, mingle more closely, and return to ”normal,” not everyone can board that train. Connie Taylor Connie Taylor, 60, from Nashville, is as tired as the next person of the COVID-cautious routines. “It’s getting old,” she said recently. Despite that, she […]
