Immunization (anti-Spike protein IgG concentration in the sera of the individuals) according to the vaccine technology.

Vaccine Technology	Antibody Concentration (AU/mL) a	Vs. Other Technology	Adjusted p-Value e
Viral vector vaccines	182.75 [144.94–220.56]	Whole-virus vaccines	1.000
		Gene vaccines	<0.001
