Abstract

Introduction: thousands of dollars are being invested for research on COVID 19 pathogenesis, treatment and prevention. To prevent COVID 19, at least 90 vaccines have been developed with the hope for providing immunity. Objective: to describe the progression of SARS-COV-2 full vaccination by age group by territorial entity in Colombia, in the period between February 17 and August 21 2021. Methodology: an analytical cross-sectional study specifically designed to gather information on vaccines administered in Colombia by age group; using the information released in the Ministry of Health and Social Protection webpage based on the COVID 19 national vaccination plan. Results: the highest full vaccination by age group was found in people in the 50 to 59 years (2’089.980), 60 to 69 years (1’937.880), and 40 to 49 years (1’480.711) age groups. The lowest number of completed vaccination protocols by age group was found in the:12 to 19 years (55.113), 20 to 29 years (476.866) and 30 to 39 years (624.909) age groups. Conclusion: currently vaccination is the most important intervention to bring the pandemic to an end. However, the emergence of multiple SARS-COV-2 variants with reduced susceptibility to vaccine-induced immunity makes the disease to remain a threat to progress.
