  • COVID-19 Booster Increases Durability of Antibody Response

    New research from the University of Virginia School of Medicine speaks to the benefits of a COVID-19 booster.

    The new findings shed light on how mRNA boosters – both Pfizer and Moderna – affect the durability of our antibodies to COVID-19. A booster, the researchers report, made for longer-lasting antibodies for all recipients, even those who have recovered from a COVID-19 infection.

  • Pfizer and BioNTech submits EUA for adapted bivalent COVID-19 vaccine in Children

    Pfizer Inc and BioNTech SE announced that the companies have submitted an application to the U.S. Food and Drug Administration (FDA) for emergency use authorization (EUA) of their Omicron BA.4/BA.5-adapted bivalent COVID-19 vaccine as the third 3-µg dose in the three-dose primary series for children 6 months through 4 years of age. With the high level of respiratory illnesses currently circulating among children under 5 years of age, updated COVID-19 vaccines may help prevent severe illness and hospitalization.

  • The off-patent drug that could protect us from future COVID-19 variants

    Scientists have identified a drug that can be repurposed to prevent COVID-19 in research involving a unique mix of ‘mini-organs’, donor organs, animal studies and patients.

  • mRNA COVID vaccine elevates cardiovascular risk, finds study

    A comprehensive review and meta-analysis of published research confirm that young adults (40 years old and younger) have a slightly elevated risk for myocarditis or pericarditis after mRNA COVID-19 vaccination. The analysis is reported in a new study in the American Journal of Preventive Medicine, published by Elsevier.

  • USFDA Grants Emergency Use Authorization for Novavax COVID-19 Vaccine

    Novavax, Inc a biotechnology company dedicated to developing and commercializing next-generation vaccines for serious infectious diseases, today announced that the Novavax COVID-19 Vaccine, Adjuvanted (NVX-CoV2373) has received emergency use authorization (EUA) from the U.S.

  • FDA authorizes Moderna and Pfizer BioNTech vaccines for child booster

    The U.S. Food and Drug Administration amended the emergency use authorizations (EUAs) of the Moderna COVID-19 Vaccine, Bivalent and the Pfizer-BioNTech COVID-19 Vaccine, Bivalent to authorize their use as a single booster dose in younger age groups. The Moderna COVID-19 Vaccine, Bivalent is authorized for administration at least two months following completion of primary or booster vaccination in children down to six years of age.

  • Simple nasal wash reduces COVID-19 severity

    Simple nasal washes with mild saline water can prevent hospitalisation and deaths from COVID-19, if applied twice daily following a positive diagnosis, according to research led by the US-based Augusta University.

  • Common mutation linked to COVID mortality

    it may be the most baffling quirk of COVID: What manifests as minor, flu-like symptoms in some individuals spirals into severe disease, disability, or even death in others. A new paper published in Nature may explain the genetic underpinnings of this dichotomy.

  • Neutralizing antibodies from single COVID-19 booster steadily decline

    Neutralizing antibody levels against the original COVID-19 virus and omicron variants in vaccinated adults tend to decline by at least 15% per month after a single booster shot, a new study using serum from human blood samples suggests. 

    Data from two adults in the same study who had a dramatic loss in antibodies but received a second booster showed that the second dose completely restored antibodies to protective levels.
