The Omicron variant of the coronavirus does not have a negative effect on cardiovascular health in young adults who have been vaccinated, a small study suggests. Additionally, women should not delay routine mammograms after receiving a COVID-19 mRNA vaccine, experts now say.
Study: mRNA vaccines perform better against COVID-19 variants of concern

A chain of events possibly triggered by unrecognized infection with the SARS-CoV-2 coronavirus could be causing the mysterious cases of severe hepatitis reported in hundreds of young children around the world, researchers suggest.
The European Center for Disease Prevention and Control said the number of unusual pediatric hepatitis cases reached 450, double the number reported two weeks earlier.
Half of the COVID-19 patients discharged from a Chinese hospital in early 2020 still have at least one symptom two years later, a new study shows. Additionally, new findings suggest patterns of inflammatory proteins in the blood of people with long COVID may someday help guide individualized treatment.
A study published in Nature Communications describes how researchers at the United Kingdom Research Institute at the University of Cambridge stumbled upon a potential target of dementia research.
Cancer diagnosis a year before infection not linked to worse outcomes; air travel carries COVID risks
Airline passengers, Airlines, Airports, Cancer, Cancer diagnosis, Coronavirus Infections, COVID-19 Mortality, COVID-19 Studies, COVID-19 transmission, Hospitalized COVID-19 Patients, Journal of Travel Medicine, R&DPatients diagnosed with cancer more than a year before contracting COVID-19 and those not receiving active treatment may be no more vulnerable to worse COVID outcomes than those without cancer, according to a new study. Additionally, researchers warned that passengers are still at risk of coronavirus infection while traveling on airplanes and also in airports.
Obesity may weaken vaccine protection; unvaccinated Omicron patients face risk from variants

Additionally, South African researchers have found infection with the Omicron variant of the coronavirus can significantly improve the immune system’s ability to protect against other variants, but only in people who have been vaccinated.
COVID worsens asthma in children; booster after infection not as beneficial vs Omicron

Additionally, among people who were previously infected with the coronavirus, a third dose of an mRNA vaccine from Pfizer/BioNTech or Moderna may not boost their protection against the Omicron variant of the virus, according to new data.
Moderna files for U.S. authorization of COVID shot for kids under 6
