Yes, there have been documented cases of ITP following COVID-19 vaccines, though they are rare. Common treatments that doctors typically prescribe include:

1. Corticosteroids (like prednisone)
2. IVIG (Intravenous immunoglobulin)
3. TPO receptor agonists (like Promacta/eltrombopag)
4. In some cases, rituximab

Every case is unique, so your hematologist will determine the best treatment based on your platelet counts and symptoms.

Always consult your healthcare provider before making any treatment changes.
