Researchers gave 31 patients with hereditary angioedema (a rare condition causing sudden swelling attacks) two doses of the Pfizer COVID-19 vaccine to see if the shots would trigger more attacks or cause problems. While a few patients did have swelling attacks shortly after the first shot, the vaccine did not increase attack frequency overall, and patients' disease control actually improved after vaccination.
All vaccinated patients developed protective antibodies against COVID-19 just like healthy people did, confirming the vaccine worked in this population.
