COVID-19 Clinical Trial
Official title:
Multicenter,Randomized,Observational Blind Phase IIB Clinical Trial to Evaluate the Effectiveness,Immunogenicity and Safety of Two Doses of CoronaVac (Sinovac) Vaccine Against Two Doses of Inactivated COVID-19 Vaccine (TURKOVAC) in Healthy Adolescent (12-18 Years) Subjects
This study is a multi-center, randomized, national, observer-blinded, active-controlled phase IIB clinical trial to determine the efficacy, immunogenicity, and safety of two-doses of inactive COVID-19 vaccine (TURKOVAC) vaccine versus the two-doses CoronaVac (Sinovac) vaccine in healthy adolescents aged 12-18 years.
The primary aim of the study is to evaluate the clinical efficacy of two-doses of TURKOVAC and two-doses of CoronaVac vaccines against symptomatic COVID-19 disease confirmed by real time-polymerase chain reaction (RT-PCR) in adolescents (12-18 years of age). After the second dose of vaccine administration, the immunological responses of TURKOVAC and CoronaVac vaccines will be demonstrated by neutralizing antibodies and anti-spiked antibodies. A total of 644 subjects will be enrolled. Subjects will be assigned according to randomization (1:1) for 2 different arms. The assigned vaccine will be administered to subjects in two doses on days 0 and 28. ;
