BACKGROUND In a previous Phase 1/2b malaria vaccine trial testing the 3D7 isoform of the malaria vaccine candidate Merozoite surface protein 2 (MSP2), parasite densities in children were reduced by 62%. However, breakthrough parasitemias were disproportionately of the alternate dimorphic form of MSP2, the FC27 genotype. We therefore undertook a dose-escalating, double-blinded, placebo-controlle...
We evaluated the immunogenicity and reactogenicity of diphtheria, tetanus, whole-cell pertussis and hepatitis B (DTPw-HB) combination vaccine manufactured by Shantha Biotechnics Pvt Ltd, Hyderabad, India in healthy infants between 6 and 8 weeks of age. Overall 123 infants (male:female ratio, 1:1.3) were recruited, of which 112 received all three doses of the vaccine at 6, 10 and 14 weeks of age...
BACKGROUND Pertussis occurs in older children, adolescents and adults due to waning immunity after primary vaccination. Booster vaccination for pre-school children has been recommended in Italy since 1999. In this study (NCT00871000), the immunogenicity, safety and reactogenicity of a booster dose of reduced-antigen content diphtheria-tetanus-acellular pertussis-inactivated poliovirus vaccine (...
The continued participation of volunteers in clinical trials is crucial to advances in healthcare. Few data are available regarding the satisfaction and impressions of healthy volunteers after participation in phase I trials, many of which lead to unexpected adverse events. We report feedback from over 100 adult volunteers who took part in a first-in-human trial conducted in a high-income count...
Hepatitis B is a major problem in many parts of the world. The WHO has recommended the inclusion of hepatitis B vaccines in routine immunization schedules. We wanted to compare two recombinant hepatitis B vaccines in an infant population for immunogenicity and reactogenicity when given at 6, 10, and 14 weeks of age. One hundred seventy-three infants meeting eligibility criteria were given eithe...
This was a multicenter, blinded, Phase II study (NCT00880893) conducted in Singapore. The primary objectives were to evaluate the safety of a tetravalent dengue vaccine (TDV) comprising four recombinant, live, attenuated viruses (CYD-TDV) and the dengue virus serotype-specific antibody responses before and 28 d after each vaccination. Participants were randomized 3:1 to receive three doses of C...
