Hepatitis A antibody persistence 8 and 10  years after 1-dose and 2-dose vaccination in children from Panama.

CONCLUSION: Anti-HAV antibody persistence was observed in lower percentages of children receiving 1 dose versus 2 doses of Havrix, at 8 and 10 years post-vaccination in Panama. Further investigations are needed to confirm antibody persistence and conclude on the protection afforded beyond 10 years in the pediatric population in Latin America.
