Resumen
The present study analyzes the humoral immune response in 319 inhabitants of San Lorenzo, Argentina, vaccinated with two doses of different anti-SARS-CoV-2 vaccines. The results show that almost all participants developed Anti-S antibodies, with the Sinopharm vaccine being less effective compared to AstraZeneca, Sputnik V and Moderna. The population was divided according to variables such as sex, age, history of Covid-19 and comorbidities, and it was evident that both people with a history of the disease and those with comorbidities had elevated antibody levels. No significant differences in immunogenicity were found with respect to sex or age, confirming a high response in older adults. The main limitation was a fixed cut-off point of 250 U/ml, which prevented detailed comparisons between schemes. This study suggests the effectiveness of all vaccination schedules studied and underlines the need for future research on the durability of the immune response.
