Study: Pregnancy nearly doubles risks of breakthrough COVID-19

(The Hill) — A study published on Thursday found that pregnancy nearly doubles the risk of breakthrough COVID-19 cases, closely followed in risk by a solid organ transplant.

The study conducted by Wisconsin-based company Epic found that among the comorbidities that increase the risk of a breakthrough COVID-19 infection, pregnancy increased this risk the most by 1.91 times, which analyzed data from over 140 million patients from 161 of the company’s organizations. 

Individuals were 1.83 times more likely to have a breakthrough COVID-19 infection if they had a solid organ transplant; those with an immune system deficiency were 1.63 times more at risk, according to the study.
