Also for tetanus and pertussis the new Brazilian combination was as immunogenic as the European counterpart, except the diphtheria seroprotection rates and titers were lower. The Brazilian combination was highly immunogenic with Hib seroprotection rates (anti- PRP > 0.15 mg /ml of 98% after 2 doses and 100% after 3. The objective of this study was to compare the immunogenicity and reactogenicity of an extemporaneously mixed DTPw/Hib (diphtheria-tetanus-whole cell pertussis combination, using the technology of two Brazilian manufacturers, against a licensed DTPw/Hib European combination in 108 infants vaccinated at 2, 4 and 6 months according to the local national schedule. The routine use of Hib vaccine is facilitated by the introduction of combination vaccines into the EPI (Expanded Plan of Immunization. This may be of relevance to North American indigenous populations characterized by suboptimal living conditions and young age of onset for whom PRP-OMP continues to be recommended, such as Alaska Natives.įeasibility study of the immunogenicity and safety of a novel DTPw/Hib ( PRP-T Brazilian combination compared to a licensed vaccine in healthy children at 2, 4, and 6 months of age Estudo de viabilidade de imunogenicidade e segurança de uma nova vacina brasileira combinada DTPw/Hib ( PRP-T, comparada com uma vacina registrada, em crianças de 2, 4 e 6 meses de idadeĭirectory of Open Access Journals (Sweden)įull Text Available Vaccination of infants with conjugated Haemophilus influenzae type b (Hib vaccines has been proven to reduce Hib meningitis by 95% and pneumoniae by 20%. ![]() We found no change in Hib incidence among indigenous Australian children living in high-incidence regions in the first 4 years following a change to PRP-T-containing combination vaccines. The indigenous:nonindigenous incidence rate ratio increased to 43 (95% CI: 16, 145) and 58 (95% CI: 7, 2660) in the later PRP-OMP and PRP-T periods, respectively, more than 10-fold higher than in lesser-incidence Australian regions. ![]() ![]() Analytic descriptive study of 20 years of enhanced surveillance data (1993-2013) for invasive Hib disease in Australian children PRP-OMP period (1993-1996) to 6.2 (95% CI: 4.0, 9.2) and 4.7 (95% CI: 1.7, 10.3) in the later PRP-OMP (1996-2009) and PRP-T periods (2009-2013), respectively. In Australia, PRP-OMP vaccines were exclusively used in indigenous children from 1993 until they were replaced by PRP-T between late 20. Menzies, Robert Ian Bremner, Kyla Margaret Wang, Han Beard, Frank Hudson McIntyre, Peter BruceĪmong indigenous populations with high incidence and early onset of invasive Haemophilus influenzae type b (Hib) disease, PRP-OMP vaccines are used in the United States and PRP-T vaccines in Canada. ![]() Long-term trends in invasive Haemophilus influenzae type B disease among indigenous Australian children following use of PRP-OMP and PRP-T vaccines. ![]()
