Brief Summary
The study is a single-center, randomized and double-blinded trial to evaluate the immunobridging between different manufacture scales, lot-to-lot consistency of the Recombinant Novel Coronavirus Vaccine (Adenovirus Type 5 Vector)(Ad5-nCOV) in population 6-59 years of age. The immunobridging between different manufacture scales will be evaluated first, the immunobridging between different age groups will be evaluated second, the lot-to-lot consistency will be evaluated at last.
