INTRODUCTIONPENTAXIM™ (Sanofi), DTaP-IPV//Hib, a pentavalent combination vaccine for protection against diphtheria, tetanus, pertussis, poliomyelitis, and invasive infections caused by Haemophilus influenzae type b, has been licensed in South Korea by the Ministry of Food and Drug Safety (MFDS) on May 9, 2016, and is currently used in routine vaccination. The aim of this phase IV study, conducted as a post-licensure commitment in South Korea, was to evaluate the safety of the DTaP-IPV//Hib vaccine when administered in infants at 2, 4, and 6 months of age in the real-world clinical practice.METHODSThis multicenter, observational, post-marketing surveillance (PMS) study was conducted in real-world practice in South Korea. Infants aged 2 months or older were enrolled across seven centers from July 31, 2018 to February 11, 2020. The study outcomes included occurrence, time to onset, duration, intensity, and causality assessment (for unsolicited adverse events [AEs] only) for several pre-listed solicited injection-site and systemic reactions, unsolicited AEs, and serious adverse events (SAEs).RESULTSData from 619 participants were included in the safety analysis. Overall, 618 AEs were reported by 273 (44.1%) participants consisting of 121 solicited injection-site reactions (15.4%), 344 solicited systemic reactions (24.6%), and 153 unsolicited AEs (15.7%) of which, 124 were unexpected AEs (12.9%) (regardless of intensity). None of the unsolicited AEs were reported to have a causal relationship with the study vaccine. One SAE of pyrexia (solicited reaction) was reported. Most AEs were of mild intensity, and all participants recovered.CONCLUSIONThis PMS study of the DTaP-IPV//Hib vaccine confirmed its safety profile in a real-life setting in South Korea and justified that the vaccine is well tolerated when used in infants aged 2 months or older for the primary series.

BACKGROUNDThe DTaP-IPV/Hib combination vaccine can replace the acellular tetanus vaccine, polio vaccine, and the Haemophilus influenzae type B vaccine. Data on the safety of DTaP-IPV/Hib vaccines are required. We aimed to evaluate the safety of the vaccination program.METHODSUsing the National Adverse Events Following Immunization (AEFI) surveillance system (CNAEFIS) in Guangzhou, China, a retrospective study was performed from May 11, 2011, to December 31, 2017. There were 376 cases of adverse events after vaccination with the DTaP IPV/Hib vaccine. The primary analysis indicators were the number of vaccines used, the number of AEFI reports received, and the reporting rate (per 100,000).RESULTSFrom May 1, 2011, to December 31, 2017, 516,000 doses of vaccine were inoculated, and 376 cases of adverse reactions were reported; the reporting rate was 72.8 per 100,000 vaccines. There were eight cases of serious AEFIs (1.5 per 100,000), with four cases of thrombocytopenic purpura (0.8 per 100,000); three cases of cyanosis of the lips, stiffness, and flexion of limbs, and convulsions (0.6 per 100,000); and one case of a high fever (0.2 per 100,000). The highest incidence of AEFIs occurred after the fourth dose (n = 207, 55.0%, 40.1 per 100,000), followed by the first dose (n = 81, 21.5%, 15.7 per 100,000), second dose (n = 48, 12.8%, 9.3 per 100,000) and third dose (n = 40, 10.6%, 7.7 per 100,000). The AEFI incidence was higher after injection of the vaccine into the deltoid muscle of the upper arm (n = 276, 73.4%, 53.5 per 100,000) than after injection of the vaccine into the thigh (n = 100, 26.6%, 19.4 per 100,000). There was a significant difference between AEFIs after injection into the deltoid of the upper arm deltoid and the thigh (x² = 164.8, P < 0.05).CONCLUSIONSMost of the reported AEFIs after DTaP-IPV/Hib vaccination are not serious. There were four cases of TP in this study; vaccination may be a rare cause of thrombocytopenic purpura.

Background:The live, attenuated, tetravalent dengue vaccine (CYD-TDV) is licensed in a number of dengue endemic countries for individuals ≥9 years of age. Before the integration of any vaccine into childhood vaccination schedules, a lack of immune interference and acceptable safety when coadministered with other recommended vaccines should be demonstrated.Methods:This randomized, multi-center phase III trial was conducted in Mexico. Healthy toddlers (n = 732) received a booster dose of a licensed pentavalent combination vaccine [diphtheria, tetanus, acellular pertussis, inactivated polio vaccine and Haemophilus influenzae type b (DTaP-IPV//Hib)] either concomitantly or sequentially, with the second dose of CYD-TDV administered as a 3-dose schedule. Antibody titers against diphtheria toxoid, tetanus toxoid and pertussis antigens were measured by enzyme-linked immunosorbent assay. Antibodies against poliovirus and dengue serotypes were measured using a plaque reduction neutralization test. Noninferiority was demonstrated for each of the DTaP-IPV//Hib antigens if the lower limit of the 2-sided 95% confidence interval of the difference in seroconversion rates between the 2 groups (CYD-TDV and placebo) was ≥10%. Safety of both vaccines was assessed.Results:Noninferiority in immune response was demonstrated for all DTaP-IPV//Hib antigens. After 3 doses of CYD-TDV, no difference was observed in the immune response for CYD-TDV between groups. There were no safety concerns during the study.Conclusion:Coadministration of the DTaP-IPV//Hib booster vaccine with CYD-TDV has no observed impact on the immunogenicity or safety profile of the DTaP-IPV//Hib booster vaccine. No difference was observed on the CYD-TDV profile when administered concomitantly or sequentially with the DTaP-IPV//Hib booster vaccine.
