Comparison of safety and immunogenicity between Healive®, Havrix® and live attenuated Hepatitis A vaccines in pediatric population: a systematic review with meta-analysis

Resumo original em inglês

O que aconteceu

Healive is an inactivated vaccine for hepatitis A virus developed in China and was found to be well-tolerated and highly immunogenic in adults and children. It is our aim this study to compare the safety and immunogenicity of Healive® with Havrix® and live attenuated vaccines in pediatric populations.

A systematic search of PubMed, Scopus, Web of Science, and Embase databases was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) comparing Healive with other vaccines were included.

O que encontraram

Seven RCTs involving 3664 patients were included. Healive showed comparable efficacy to Havrix regarding seroconversion rates and GMT at one month (SMD = 0.24, 95% CI [-0.11 to 0.59]), but achieved better results at six (SMD = 0.85, 95% CI [0.57 to 1.07]) and seven months (SMD = 0.55, 95% CI [0.41 to 0.70]). When compared to live attenuated vaccines, Healive demonstrated superior GMT at one month (SMD = 0.31, 95% CI [0.07 to 0.56]) and two years (SMD = 0.36, 95% CI [0.06 to 0.67]).

Por que isso importa

Healive appears to be effective and safe for preventing hepatitis A, providing at least five years of protection. This review underscores the importance of ongoing research to optimize hepatitis A vaccination strategies, including standardized assays for antigen content, clarification of protective antibody levels, and large-scale trials in regions of intermediate endemicity.
