People with substance use disorders may be at higher risk for SARS-CoV-2 breakthrough infections: Co-occurring health disorders appear to contribute to increased risk, NIH study suggests. An analysis of electronic health records of nearly 580,000 fully vaccinated people in the United States found that the risk of SARS-CoV-2 breakthrough infection among vaccinated patients with substance use disorders was low overall, but higher than the risk among vaccinated people without substance use disorders. People with substance use disorders—such as alcohol, cannabis, cocaine, opioid, and tobacco use disorders— also had elevated rates of severe outcomes, including hospitalization and death, following breakthrough infections.
