Long COVID risk significantly higher in unvaccinated: Study
A cohort study found that the risk of developing persistent post–COVID-19 symptoms, or long COVID, was significantly higher in unvaccinated participants and those initially hit harder by the virus. The research, published Wednesday in JAMA Network Open, showed that six months after onset, long-COVID participants had a significantly higher risk of pulmonary, diabetes, neurological, and mental health issues than they did preinfection.

Vaccinated moms’ breast milk may protect babies from COVID-19
University of Florida researchers have provided additional evidence that the breast milk of mothers vaccinated against COVID-19 helps protect infants too young to receive the vaccine. The findings, published January 12 in the Journal of Perinatology, found SARS-CoV-2 antibodies in the stool of infants who consumed this breast milk. Read More
Severe COVID-19 outweighs rare post-vaccination myocarditis risk
Researchers from Brigham and Women’s Hospital and Massachusetts General Hospital investigated the immune response of young adults who developed myocarditis after receiving a COVID-19 vaccine. The study, published January 4 in the journal Circulation, indicated that the risk of developing severe disease from acute COVID-19 infection significantly outweighed the rare risk of post-vaccine myocarditis.

COVID-19 vaccine appears safe for children following MIS-C
Children and adolescents who received a COVID-19 vaccination following multisystem inflammatory syndrome (MIS-C) reported no serious complications, including myocarditis or reoccurrence of MIS-C. The NIH-funded observational study, published January 3 in the journal JAMA Network Open, indicates that it is safe to get a vaccine after having had MIS-C. Read More
Mechanism revealed for COVID-19-related loss of smell
Duke Health scientists and collaborators have discovered an inflammatory mechanism that helps explain COVID-19-related loss of smell, and possibly other long COVID symptoms. The finding, published December 21 in the journal Science Translational Medicine, provides insight into a problem that has plagued millions who have not recovered their sense of smell following COVID-19 infection.

Short-lived nasal antibodies against COVID-19 may explain reinfection
Research led by the University of Liverpool and Imperial College London found that antibodies produced in the nose decline nine months after COVID-19 infection, while antibodies in the blood last at least a year. Read More
Plant offers potential for massive scale production of COVID-19 tests, vaccines
Viral antigen-based diagnostic tests as well as various vaccines have been key tools in fighting COVID-19. Read More
Discovery of toxin linked to severe COVID-19 points to new way to treat disease
A viral toxin produced by the SARS-CoV-2 virus may damage cell barriers, inducing vascular leak and driving severe COVID-19 infections, according to researchers at the University of California, Berkeley (UC Berkeley). Read More
New drug 'fakes out' SARS-CoV-2 to neutralize it
A new drug neutralizes SARS-CoV-2 and its variants by acting as an ACE2 receptor decoy, Dana-Farber Cancer Institute researchers revealed. Read More
Vaccines offer long-term protection against severe COVID-19 in monkeys
New research indicates that two-dose experimental SARS-CoV-2 vaccines provide protection against COVID-19-related lung disease in year-old rhesus macaques vaccinated as infants. Read More
