Abstract
Vaccination has traditionally been one of the primary prevention activities to which most effort has been devoted in Spanish penitentiary institutions. Once again, the type 2 coronavirus pandemic causing severe acute respiratory syndrome (SARS-CoV-2) pandemic has highlighted the importance of vaccination in the control of immunopreventable diseases. After overcoming the health emergency caused by the coronavirus disease 2019 (COVID-19), we face the challenge of recovering the vaccination coverage we had before the pandemic, in addition to increasing the coverage of other vaccines with lesser implantation in our environment. Among the improvement strategies to be implemented would be the optimization of the transmission of health information between penitentiary centers dependent on different administrations. It would also be desirable to be able to access the vaccine information systems of the different autonomous communities, both to know the vaccination status of patients and to report the doses administered during the period of internment, as well as to improve the vaccine statistics available in prison.
