A new study suggests that individuals with a history of certain mental illnesses may be at a higher risk of COVID-19 breakthrough infections after being vaccinated.
Researcher Kristen Nishimi said that could be because patients with some psychiatric disorders can have a "decreased immunological response to vaccine."
The researchers found that for patients under 65, the risk of developing a COVID-19 breakthrough infection was up to 11 per cent higher for those who had been diagnosed with a psychiatric condition. And for patients 65 or over, having a psychiatric history represented up to a 24 per cent higher risk of COVID-19.
" may require more frequent in-person care, which could increase their interactions with the health-care system," Nishimi said in aFor both groups, the risk factors were also adjusted for variables such as age, race, vaccine type, underlying conditions The risk factors varied based on the type of condition. For patients 65 and over, the study found that the risk of having a breakthrough infection was 24 per cent higher among people with a history of substance abuse, 23 per cent higher for those with psychotic disorder, 16 per cent higher for bipolar disorder, 14 per cent for adjustment disorder and 12 per cent for anxiety.
