BOSTON - As the speed and scale of vaccinations against the SARS-CoV-2 virus ramps up globally, researchers at Massachusetts General Hospital (MGH) are calling for greater awareness and communication around a delayed injection-site reaction that can occur in some patients who have received the Moderna mRNA-1273 vaccine.
In a letter to the editor published online in The
New England Journal of Medicine (NEJM), the authors note Phase 3 clinical data from the Moderna vaccine trial did show delayed skin hypersensitivity in a small number of the more than 30,000 trial participants. However, the authors say the large, red, sometimes raised, itchy or painful skin reactions were never fully characterized or explained, and they warn clinicians may not be prepared to recognize them and guide patients on treatment options and completion of the second dose of the vaccine.
