    Open AccessHannah Melchinger, Sameer M Belgaumi et al.ARTICLEPLOS Global Public Health2025

    Influenza vaccines are essential against the spread of influenza virus. In the United States, the Centers for Disease Control and Prevention (CDC) recommends vaccination to all eligible individuals over 6 months of age; however, uptake remains suboptimal nationally. We do not fully understand the current nuances of influenza vaccine uptake, nor how it has been affected by the coronavirus disease 2019 (COVID-19) pandemic. From 2020-2024, we conduc…

  • Is health, growth and development impaired in children who are Hepatitis B-exposed but uninfected

    Open AccessSheila F Lumley, Elaine Parker et al.ARTICLEPLOS Global Public Health2025

    An estimated 254 million people are living with chronic hepatitis B virus (HBV) infection worldwide. Many infants are born to mothers with HBV but do not themselves acquire the infection. It is unclear whether this exposure to HBV in early life - without the development of active infection - may be associated with adverse outcomes. We propose the term “HBV-exposed uninfected (HBEU)”, drawing parallels with the HIV field which recognises that chil…
