Health Canada is updating the labels for the AstraZeneca and Johnson & Johnson COVID-19 vaccines to add immune thrombocytopenia (ITP), an autoimmune condition, as a potential side effect.
In a statement on Tuesday, the agency said very rare cases of ITP have been reported internationally after receiving the Vaxzevria (AstraZeneca) and Janssen (J&J) COVID-19 vaccines.
ITP is a disorder that can cause easy or excessive bruising and bleeding, which results from unusually low blood platelet levels.
