Impact of frequency and duration of freeze-dried inactivated tissue culture hepatitis A vaccine (Aimmugen ®) vaccination on antibody titers; a japanese cross-sectional study

Additionally, four or more doses may be effective when there is a need to ensure long-term immunity or risk of prolonged exposure.PMID:37620202 | DOI:10.1016/j.vaccine.2023.08.030
