Concomitant administration of varicella vaccine with combined measles, mumps, and rubella vaccine in healthy children aged 12 to 24 months of age.
The reactogenicity and immunogenicity of three combined measles, mumps and rubella (MMR) vaccines and one administered with a varicella vaccine was studied in infants. The vaccines were Priorix (designated MeMuRu, Group 1), M-M-R II (Group 2), Triviraten (Group 3) and Priorix + a varicella vaccine, Varilrix (Group 4). Fever was greater in Group 2 (61.3%) compared to Group 1 (48.5%; p = 0.033) or Group 3 (37.1%; p = 0.009). Rash with fever was reported in Group 2 (4.8%) and Group 4 (3.3%), but not for Group 1. Anti-measles, -mumps and -rubella seroconversion was similar for Group 1 (96.1%, 96.1% and 100%, respectively), Group 4 (98% for all three), and Group 2 (91.5%, 93.6% and 97.9%) 60 days post-vaccination. GMTs for measles (3,053.7-3,412.2 mIU/ml), mumps (1,001.5-1,158.8 U/ml) and rubella (68.7-89.1 IU/ml) were similar for Groups 1, 2 and 4 at Day 60. Antibody persistence was noted 2 years post-vaccination. The MeMuRu + varicella combination showed no clinically relevant increase in reactogenicity and should facilitate introduction of a varicella vaccine into national immunization schedules.
