简介
Background:
Preliminary results in healthy, young US adults showed that a tetravalent, live-attenuated dengue vaccine (TDV) was safe and immunogenic, but no data are available in children.
Methods:
In a multicenter, randomized, controlled, observer-blinded study in the city of Mexico, children aged 2 to 5, 6 to 11, and 12 to 17 years (36 children per age group), and adults (n= 18) aged< 45 years received the following: 3 injections of TDV at months 0, 3.5, and 12 (TDV-TDV-TDV), or 1 injection of yellow fever vaccine (YF) at month 0, and 2 injections of TDV at months 3.5 and 12 (YF-TDV-TDV). Adverse events and biologic safety (biochemistry and hematology) were documented. Plaque reduction neutralization test (PRNT 50) antibody titers against the TDV parental viruses were measured 28 days after vaccination. Seropositivity was defined as antibody titers≥ 10 1/dil.
Results:
No vaccine-related serious adverse …
