Breakthrough COVID-19 infections more severe, likely in immunocompromised individuals: Pfizer study – CTV

November 30, 2021

TORONTO — A study involving more than a million fully vaccinated people found that COVID-19 breakthrough infections were more common among immunocompromised individuals and were far more likely to lead to hospitalization or death.

Researchers from Pfizer published their findings in the Journal of Medical Economics on Tuesday. They looked at 1.2 million people in the U.S. who had received both doses of the company’s mRNA vaccine for COVID-19 between December 2020 and July 2021 in what they claim is the largest study of its kind.

“Several countries are currently experiencing a resurgence of SARS-CoV-2 infections despite the rollout of mass vaccination programs.
