Equitable access to vaccination against COVID-19 is a challenge in various regions of the world. In Peru, the Venezuelan population is a vulnerable group that has suffered the greatest impact of the pandemic due to lack of access to health services. The aim of the present study was to determine the factors associated with non-vaccination against COVID-19 in the Venezuelan immigrant population residing in Peru. A cross-sectional study will be conducted on the data obtained from the Second Survey of the Venezuelan Population Residing in Peru. The dependent variable was whether or not the migrant was vaccinated against COVID-19, defined as "Yes" if the person gave a positive response and "No" otherwise. The independent variables were related to the sociodemographic, economic, and migratory characteristics of the included population. Crude and adjusted generalized linear Poisson family models were used to calculate prevalence ratios (PR) with 95% confidence intervals (CI). A total of 7739 Venezuelan migrants aged 18 years or older will be included.
