COVID-19 Vaccination Update

PPMD is closely following any changes or updates to current Covid-19 vaccine recommendations, including new recommendations for immunocompromised individuals. Under guidance of the Centers for Disease Control and Prevention (CDC) to understand how current guidelines apply to people with Duchenne, we are happy to update our Covid-19 Vaccination & Duchenne resource page.

These updates reflect the need for people with Duchenne who are immunocompromised (receiving ≥20mg Prednisone daily, or ≥24mg Deflazacort daily) to receive a third dose of the Pfizer-BioNTech or Moderna vaccines at least 28 days after the second dose. These new guidelines do not apply to people who received the Johnson & Johnson/Janssen vaccine or to people who take high-dose weekend-only steroids, as immunosuppression in this population remains unclear. If you are unsure if you/your child should receive a third vaccine dose, speak with your neuromuscular team directly for recommendations specific to your situation.
