Study Highlights High Vaccination Rates Across Mental Health Groups
A large multinational study led by researchers at the Karolinska Institutet, published in Nature Communications, has found that lower COVID-19 vaccination rates are generally high among individuals with and without mental health conditions. The study, which analyzed data from five countries—Sweden, Norway, Iceland, Estonia, and Scotland—revealed that around 85 percent of participants had received their first dose of the COVID-19 vaccine by September 2021. Notably, there was no significant difference in vaccination rates between those diagnosed with a mental illness and those without.
The study, part of the COVID-19 consortium, investigates the mental health impacts of COVID-19 and examines how COVID-19 vaccination rates relate to these effects, involving data from over 325,000 individuals across five countries, along with registry data from Sweden that encompasses more than 8 million people. While the initial findings showed overall high vaccination rates, further analysis revealed important disparities within certain subgroups.
Lower Vaccination Rates Among Individuals with Unmedicated Mental Health Conditions
Although the overall vaccination rate was high, the study uncovered a concerning trend in Sweden. Individuals diagnosed with a mental illness who had not been prescribed medication were found to be 9 percent less likely to receive their first dose of the vaccine compared to the general population. This disparity raises questions about barriers to vaccination for people with untreated mental health conditions.
Additionally, the data highlighted that individuals with substance use disorders faced an even greater risk of being unvaccinated, with this group being 16 percent less likely to have received the first dose. These findings point to potential gaps in public health strategies, especially when addressing vulnerable populations who may already face greater risks from COVID-19.
Calls for Further Research to Address Gaps in Vaccination Coverage
Covid Vaccine Study Finds Links to Health Conditions
Mary Barker, one of the lead researchers, emphasized the need for further research to understand the factors behind these lower COVID-19 vaccination rates in unmedicated individuals. “More research is needed to explore the reasons behind these associations in order to improve current and future vaccination strategies,” she said. Barker stressed the importance of equitable protection against infectious diseases, particularly for people with mental health conditions, who are at higher risk of severe COVID-19 outcomes.
The study was supported by multiple organizations, including NordForsk, the EU’s Horizon 2020 program, and several Swedish and Estonian research councils. The findings underscore the importance of targeted interventions to ensure that vulnerable populations, particularly those with untreated mental health conditions, receive adequate protection through vaccination programs.
In light of the study’s findings, public health officials are encouraged to explore more inclusive approaches to vaccination outreach, ensuring that barriers such as mental health challenges and substance use disorders are addressed in future strategies.
