Introduction: The virulence factors and pathogenic mechanisms of SARS-CoV-2 allowed millions of infections and millions of deaths worldwide. Given the lack of an effective cure, the start of the immunization process was very relevant in our country, where Sinopharm and Pfizer vaccines were initially available. Clinical trials show efficacy of vaccines under ideal conditions, but it is necessary to evaluate the results of vaccine administration with respect to reducing the severity of COVID-19 cases. Methods: Cross-sectional study. A total of 386 patients older than 8 years and diagnosed with COVID-19 were included after receiving two doses of Sinopharm or Pfizer and before receiving the third dose. Information was collected from Notiweb, SisCovid, NetLab and His Minsa, databases that contain information on epidemiological monitoring of vaccinated individuals and COVID-19 cases. It was approved by the ethics committee of the National University of Trujillo. Results: A lower proportion of severe cases (3.1% vs. 4.3%) and moderate cases (30.8% vs. 32.8%) was observed in the Pfizer group, although there was no significant difference compared to participants vaccinated with Sinopharm (p>0.05). Multinomial logistic regression models showed no differences in the probability of having moderate disease (RRR: 0.95, 95% CI: 0.58-1.55) or severe disease (RRR: 1.09, 95% CI: 0.31-3.82) between those who received Sinopharm and Pfizer. Conclusions: Neither of the studied vaccines demonstrated superiority over the other regarding the lower proportion of severe and moderate cases following immunization with either of them.
