A year after infection with the coronavirus – when antibodies in the blood are barely detectable – the immune system continues to “remember” the virus and should respond to some extent upon re-encountering it, a study from China suggests. According to new research, women who were pregnant during the recent Omicron surge had more than eight times the rate of COVID-19 diagnoses, but lower odds of severe illness compared with pregnant women diagnosed earlier in the pandemic.

After producing vaccines and treatments for acute COVID-19 in record time, researchers and drugmakers are turning to finding a cure for long COVID, a more elusive target marked by hundreds of different symptoms afflicting millions of people.

People may be at increased risk for developing diabetes for up to a year after a diagnosis of COVID-19, according to two studies. Additionally, organ donation from dying donors with current or previous COVID-19 infection is likely safe, transplant teams from the United States and Italy will report at the April 2022 European Congress of Clinical Microbiology & Infectious Diseases meeting.

The most obvious risks from COVID-19 are hospitalization and death. But study after study shows the disease comes with an increased risk of a number of health problems, including diabetes.

The Omicron variant of the coronavirus is causing a dramatic rise in cases of croup, a dangerous respiratory condition usually seen in babies and toddlers, new data suggest. Additionally, new research sheds light on how a tuberculosis vaccine might help protect against COVID-19.

One in four children with COVID-19 symptoms develop “long COVID,” according to data pooled from 21 earlier studies conducted in Europe, Asia, Australia and South America. Also, according to a study reported on March 14 in JAMA Pediatrics, women who wish to pass protective antibodies induced by COVID-19 vaccines to their babies via breast milk should opt for the mRNA shots from Moderna or Pfizer/BioNTech.

An experimental vaccine developed by GeoVax Labs Inc. succeeded in promoting development of antibodies that target two different sites on the virus in a small pilot study and was advanced to mid-stage clinical trials, researchers reported.
COVID-19 patients who receive one of the few antibody treatments that works against the Omicron variant must be carefully monitored because after the drug is infused, the virus may mutate and become resistant to it, researchers warned after seeing such cases with Delta variant patients.

An Oxford University study has found that COVID-19 can cause the brain to shrink, reduce grey matter in the regions that control emotion and memory, and damage areas that control the sense of smell.

An experimental oral drug being developed by Redhill Biopharma Inc. interrupts a process that helps the coronavirus infect cells and might keep COVID-19 patients from becoming seriously ill, the company said. Additionally, the risk of hospitalization after vaccination with Johnson & Johnson’s COVID-19 vaccine was about five times higher than for those who received the Pfizer and BioNTech shot, a large French study found.

Three new studies have been released—but not yet peer-reviewed—that support the wet market theory about the origin of COVID-19.
