medwireNews: Study findings suggest that messenger (m)RNA COVID-19 vaccines have a favorable short-term safety profile in people with antiphospholipid antibodies.
“[S]ome concerns have been raised regarding the safety of the vaccines in patients with antiphospholipid antibodies, as these antibodies have been reported to appear following both infection and vaccination and have been identified in patients with COVID-19,” write Savino Sciascia (San Giovanni Bosco Hub Hospital, Turin, Italy) and team in a correspondence to The Lancet Rheumatology.
In their cohort of 52 people with antiphospholipid syndrome and 50 people with antiphospholipid antibodies but without clinical features of the syndrome, 76% experienced at least one adverse event following any dose of an mRNA vaccine, all of which were transient and self-limiting within 10 days. Symptoms were mild in 71% of patients and moderate in 29%. The researchers say that there were “[n]o major adverse events nor thrombotic events.”
Although they acknowledge that “more data are needed, including from long-term follow-up,” Sciascia et al conclude that “mRNA COVID-19 vaccines seem to have an acceptable safety and tolerability profile in patients with antiphospholipid antibodies.”
