Third dose of COVID-19 vaccine does not appear to increase severe adverse events

Investigators report that even though there was some increase in cases of low-severity adverse events after third-dose vaccination against SARS-CoV-2 infection with mRNA vaccines, such third-dose vaccination did not significantly increase severe adverse events. The findings appeared on April 14, 2022 in JAMA Network Open. As background the authors said. “Recent reports on waning of COVID-19 vaccine–induced immunity have led […]

Conventional vaccine messages miss the mark

Promotional campaigns designed to increase vaccine uptake are often ineffective, according to a new study in eight European countries. Some initiatives which highlight the benefits of immunisation may even be counterproductive, say scientists. Researchers at the Technical University of Munich worked with colleagues at the University of Trento and the London School of Economics and Political Science to test the […]

EU experts cautious on fourth dose of COVID-19

It is ‘too early’ to consider using a fourth dose of mRNA COVID-19 vaccines in the general population, according to the European Medicines Agency (EMA) and the European Centre for Disease Prevention & Control (ECDC). However, experts from both agencies agreed that a fourth dose – or second booster shot – can be given to adults 80 years of age. […]

A third of healthcare workers took sick leave after Covid vaccination, study finds

A third of healthcare workers took sick leave after being vaccinated against COVID-19, a German study presented at this year’s European Congress of Clinical Microbiology & Infectious Diseases (ECCMID) in Lisbon, Portugal, (23-26 April) has found. A healthy healthcare workforce is vital to cope with COVID-19, as well as with the pandemic’s wider effects on public health. As a result, […]

Additional COVID vaccine helps protect transplant patients

Additional booster doses of vaccine against COVID-19 are particularly important for those who are immunosuppressed, namely those who have had solid organ transplants, a new study shows. The study, published in the Journal of Infectious Diseases, shows that even after vaccination, patients taking immunosuppressive medications to prevent rejection of an organ transplant have higher risk for severe COVID-19 than those with […]

New COVID-19 nasal spray outperforms current antibody treatments in mice

A new protein-based antiviral nasal spray developed by researchers at Northwestern University, University of Washington and Washington University at St. Louis is being advanced toward Phase I human clinical trials to treat COVID-19. Designed computationally and refined in the laboratory, the new protein therapies thwarted infection by interfering with the virus’ ability to enter cells. The top protein neutralized the […]

Researchers roll out data on COVID vaccine distribution and waste

Researchers are rolling out a data set that provides detailed information on COVID-19 vaccine shipments and wastage across the United States, with the goal of spurring new data analysis to improve vaccination efforts in the future. The work stems from a collaboration between researchers at North Carolina State University and BuzzFeed News. “The development and distribution of COVID-19 vaccines has […]

Pandemic drives use of telehealth for mental health care

The COVID-19 pandemic likely permanently increased the delivery of mental health counseling through telehealth, according to new research from Oregon Health & Science University. The retrospective analysis was published today in the April issue of the journal Health Affairs. “Our study suggests that telehealth services for mental health counseling expanded significantly and is likely to stay,” said lead author Jane Zhu, M.D., assistant […]

Pandemic lockdowns had severe mental health consequences for women in the developing world

While potentially crucial to preventing the spread of COVID-19, lockdowns are associated with increased rates of depression and anxiety as well as food insecurity among women in India and other parts of the developing world, according to a new research. The study from the University of California San Diego’s School of Global Policy and Strategy finds that women whose social […]
