There was no difference in COVID-19 vaccine hesitancy between PWID residing in San Diego vs. People without reliable transportation may have faced additional barriers to access.Īn earlier study conducted by our binational team found that only 7.6% of PWID living on either side of the San Diego-Tijuana border reported having had at least one COVID-19 vaccine dose by September 2021, and nearly one-third reported being vaccine hesitant ( 17). Additionally, some COVID-19 vaccine queues were very long. For low income residents such as most PWID, this may have represented a financial burden since those lacking computer or smartphone access were required to pay for computer time and printouts. As in other Mexican cities, individuals in Tijuana seeking COVID-19 vaccination were required to register online and enter their CURP ( Clave Única de Registro de Población Mexican official unique identifier) to obtain an appointment and were asked to print the appointment card or present their CURP to verify their identity ( 18), which has been shown to be a barrier to health services in other settings ( 19). ![]() In Tijuana, Baja California, Mexico's most northwestern state abutting California, United States, COVID-19 vaccines became available according to the above schedule at mass vaccination sites throughout the city, where SinoVac-CoronaVac®, Oxford-AstraZeneca®, and J&J/Janssen® vaccines were offered ( 14).īy June 25, 2021, Baja California reported being close to becoming the first state in Mexico to achieve full vaccination for most of its adult residents ( 15, 16) following a donation of J&J/Janssen vaccine from the United States however, vaccine uptake was lower in some marginalized populations ( 17). Stage 4 (June to July 2021) expanded to persons 40 years or older, and finally, Stage 5 vaccinating the general population beginning in July 2021 ( 12). Efforts expanded with Stage 3 (May to June 2021) prioritizing pregnant women in the second or third trimester and persons 50 years or older. In Stage 2 (February to May 2021), vaccination efforts were prioritized to municipalities with concentrated COVID-19 mortality, starting with those 60 years old and older ( 11, 13). In Stage 1, Mexico vaccinated 100% of their healthcare personnel (1.25 million people) between December 2020 and February 2021 ( 12). Mexico developed five stages for vaccination rollout ( 11). In Mexico, SARS-CoV-2 has caused over 5.5 million cases of COVID-19 ( 10). Due to the high COVID-19 burden among PWID, there is a need to expand COVID-19 vaccination efforts for this population ( 2, 8, 9). ![]() Additionally, PWID have limited access to health care services and often experience stigma and discrimination that perpetuates medical mistrust, contributing to poor health care utilization ( 6, 7). PWID may experience severe COVID-19 illness due to comorbid conditions, including chronic kidney, liver and lung diseases ( 1, 3– 5). In a previous study of people who inject drugs (PWID) in Tijuana and San Diego, SARS-CoV-2 prevalence was 37.5%, which was higher than the general population in both cities ( 2). Individuals with a diagnosis of substance use disorder, including opioid use disorder, have significantly higher risk of acquiring SARS-CoV-2 and worse clinical outcomes than other COVID-19 patients ( 1).
