Impact of vaccination strategy adjustments on antibody levels against measles, rubella, mumps, and varicella in China: a single-center serological survey.
Serological survey showed increased antibody levels for rubella, mumps, and varicella in healthy participants, suggesting improved population immunity while measles levels declined.
Key Points
Optimized two-dose vaccination strategies significantly improved seropositivity rates for rubella, mumps, and varicella.
Incidence of varicella, rubella, and mumps showed marked declines post-policy adjustments, indicating successful public health efforts.
Serological analysis revealed declines in measles seropositivity, highlighting vulnerabilities in immunity across populations.
Targeted strategies are essential for enhancing vaccine coverage and addressing specific demographic needs, especially for measles.
