(Reuters Health) –
Vaccination against hepatitis B seems to protect against the virus for
25 years, suggesting booster shots are unnecessary, according to a new
study from Taiwan.
“Universal vaccination in infancy provides long-term protection,” Dr. Yen-Hsuan Ni, the study’s lead author from the National Taiwan University in Taipei, wrote in an e-mail.
Taiwan mandated hepatitis B virus (HBV) immunization for all infants in 1984, in response to extremely high rates of infection. Hepatitis B infection is a prime
cause of liver cancer, the second most common cancer type in Taiwan.
