| アブストラクト | CONTEXT: In 2015 in Quebec, Canada, the passive vaccine adverse event reporting system detected an increase in large local reactions associated with vaccines recommended at the 18-month visit. This followed changes to the pediatric vaccine schedule to include hexavalent diphtheria-tetanus-acellular-pertusis-inactivated polio-Haemophilus influenzae type b-hepatitis B vaccine (DTaP-IPV-Hib-HB, Infanrix-hexa(R), GSK) and quadrivalent measles-mumps-rubella-varicella vaccine (MMRV, ProQuad(R), Merck) as 18-month booster doses. OBJECTIVES: To determine if the excess of large local reactions was caused by a specific vaccine or their co-administration in the same limb or during the same visit. METHODS: A case-control study was conducted among cases born between January 2012 and April 2015 with a large local reaction following MMR+/-V or DTaP-IPV-Hib+/-HB vaccines administered between 16 and 23months of age. Controls were randomly selected from the provincial medicare database among children born during the same period. RESULTS: Our analysis included 96 cases and 494 controls vaccinated with MMRV or DTaP-IPV-Hib+/-HB vaccines. Among the 96 cases, 46% had a cellulitis and 54% had an injection site reaction extending beyond the nearest joint and/or lasting>/=4days. Among the 39 cases who were immunized in different limbs, 77% of the large local reactions were located at the Infanrix-hexa(R) site, 5% at the DTaP-IPV-Hib site and 18% at the ProQuad(R) site. Large local reactions were significantly more frequent with Infanrix-hexa(R) than with DTaP-IPV-Hib vaccine (OR 5.9 95% CI: 1.4-25.7). Administration of ProQuad(R) and Infanrix-hexa(R) in the same limb did not increase the risk of large local reactions. CONCLUSION: This investigation suggested that most large local reactions were causally associated with the Infanrix-hexa(R) vaccine and that the risk was not greater when ProQuad(R) and Infanrix-hexa(R) were administered in the same limb. Given the improved vaccine coverage for hepatitis B, benefit-risk analysis likely still favours ongoing use of Infanrix-hexa(R) with informed parental consent. |
