Immunogenicity and safety of a combined measles, mumps, rubella and varicella live vaccine (ProQuad (R)) administered concomitantly with a booster dose of a hexavalent vaccine in 12-23-month-old infants

摘要

Background: Concomitant administration of vaccines can facilitate vaccination uptake, provided that no clinically significant effect on either vaccine is identified. We investigated the concomitant administration, during the second year of life, of one dose of the combined measles, mumps, rubella and varicella vaccine (ProQuad (R)) with a booster dose of a hexavalent vaccine.
