Summary

Phase II, non-randomized, open-label, comparative, national, multicenter trial in Mali, aimed to assess the humoral vaccine immune response induced by Ad26.COV2.S vaccine in 200 adults one month after receiving the complete vaccination schedule of SARS-CoV-2 vaccine.

Detailed description

The main objective of this phase II trial is to evaluate the humoral immune response induced by the Ad26.COV2.S vaccine in adults one month after complete vaccination regimen against SARS-CoV-2, compared younger (up to 45 years old) and elderly (55+ years old) populations. 200 participants will be included, 200 participants for each vacine.
