Here, we aimed to characterize the levels of neutralizing antibodies to live SARS-CoV-2 and the inhibition rates of neutralizing antibodies to pseudovirus, as well as the IgG and IgM responses towards the S and N proteins of SARS-CoV-2, at 180 days after two-dose vaccination with one of two different types of inactivated COVID-19 vaccine, CoronaVac and Covilo. This evidence concerns the gene CD40LG and COVID-19.
