Summary
CombiVacS is a phase 2 randomized, adaptive trial developed to evaluate the immunogenicity of
a dose of COMIRNATY after a previous single dose of VAXZEVRIA. A stratification will be made
based on the following factors: study site, sex and age. This protocol allows to test the
immunogenicity and safety of a heterologous vaccination strategy after a previous single dose
of VAXZEVRIA.
