Effects of COVID‐19 vaccination on platelet counts and bleeding in children, adolescents, and young adults with immune thrombocytopenia

alexandrossfakianakis shared this article with you from Inoreader Effects of COVID‐19 vaccination on platelet counts and bleeding in children, adolescents, and young adults with immune thrombocytopenia via Pediatric Blood & Cancer Abstract Coronavirus disease 2019 (COVID-19) vaccines rarely cause de novo immune thrombocytopenia (ITP) but may worsen preexisting ITP in adults. Whether severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines impact platelet counts and bleeding in children, adolescents, and young adults (C-AYA) with preexisting ITP is unknown. We report here the very limited effect of COVID-19 vaccination on platelet counts and bleeding in a single-center series of 2 C-AYA with ITP. No patient experienced worsening bleeding and only one child had a significant decrease in platelet count which improved spontaneously to her baseline without intervention. SARS-CoV2 vaccination was safe in C-AYA with ITP in this small cohort. View on Web
