Hypertension remains a significant risk factor for severe COVID-19 in fully vaccinated

The presence of hypertension still poses a significant risk factor for more severe disease in COVID-19, even among those fully vaccinated. Patients with hypertension even after receipt of three COVID-19 vaccination doses, remain at an elevated risk of severe breakthrough infections with the Omicron variant according to researchers from the Department of Cardiology, Cedars-Sinai Medical Center, Los Angeles, US. Although full vaccination against COVID-19 initially required individuals to have two doses, the fact that immunity appears to wane over time has led to a recommendation for a third dose. In fact, a third dose appears to provide greater protection with data showing how a third dose of the BNT162b2 vaccine administered a median of 10.8 months after the second dose provided 95.3% efficacy against COVID-19 compared with two doses.
