TORO-HUAMANCHUMO, Carlos J. et al. Booster dose with the BNT162b2 vaccine in the population that received the complete immunization schedule for COVID-19 in Peru: A critical analysis of the current evidence. Rev. Cuerpo Med. HNAAA [online]. 2021, vol.14, suppl.1, pp.70-78.  Epub Oct 30, 2021. ISSN 2225-5109.  http://dx.doi.org/10.35434/rcmhnaaa.2021.14sup1.1177.

Background: In Peru, the current immunization schedule for COVID-19 includes BBIBP-CorV, BNT162B2 and ChAdOx1 nCoV-19 vaccines. Although the full immunization schedule is two doses, some countries have recently included a booster dose to their schedule. Methods: We conducted a search for scientific evidence del artículo on the efficacy and safety of booster vaccination with BNT162b2 vaccine in a population with a complete vaccination schedule for COVID-19 in Peru. Evidence: Four evidence-based recommendation documents, one observational study and three ongoing phase III clinical trials were included for analysis. Conclusion: To date, there is insufficient evidence on the efficacy of adding a booster dose to the immunization schedule for COVID-19. The available evidence does not justify the use of a booster dose of BNT162B2 vaccine in a population that has previously received two doses of the aforementioned vaccines.
