Abstract

Insights

This study estimates measles-mumps-rubella (MMR) vaccine effectiveness, finding high seroconversion rates but also identifying waning immunity. These findings are crucial for predicting future outbreaks in highly vaccinated populations.

Area of Science:

  • Immunology
  • Vaccinology
  • Epidemiology

Background:

  • Measles-mumps-rubella (MMR) vaccine is widely used, yet outbreaks persist in highly vaccinated areas.
  • Concerns exist regarding primary and secondary vaccine failure of MMR components.
  • This study addresses the need for robust data on MMR vaccine immunogenicity and durability.

Purpose of the Study:

  • To estimate seroconversion rates for measles, mumps, and rubella components of the MMR vaccine.
  • To determine the rate of waning immunity for each component of the MMR vaccine.
  • To provide data for improved modeling of disease outbreaks.

Main Methods:

  • Systematic review and meta-analysis of randomized controlled trials, cohort studies, and longitudinal studies.
  • Searched PubMed, Web of Science, and Embase for studies published up to December 31, 2019.
  • Included studies on healthy individuals receiving trivalent MMR vaccine; excluded co-administration, maternal immunity, or non-trivalent formulations.

Main Results:

  • Estimated seroconversion rates: measles 96.0%, mumps 93.3% (excluding Rubini strain) or 91.1% (including Rubini strain), and rubella 98.3%.
  • Estimated annual waning rates: measles 0.009, mumps 0.024, and rubella 0.012.
  • Included 62 eligible studies from an initial 3615 unique studies.

Conclusions:

  • The meta-analysis quantifies primary and secondary MMR vaccine failure.
  • Findings are essential for enhancing mathematical models predicting measles, mumps, and rubella outbreaks.
  • Improved predictive modeling can aid public health strategies in highly vaccinated regions.
