Powell had numerous risk factors for such a breakthrough infection: He had been treated for a rare blood cancer called
multiple myeloma, he had been diagnosed with Parkinson’s disease, and he had a history of prostate cancer. The
combination of those chronic conditions and his advanced age placed him at a higher risk for a breakthrough infection. In addition, accumulating evidence suggests that
patients with conditions such as multiple myeloma need third doses of an mRNA vaccine (Pfizer or Moderna) to achieve immunity. The third dose in immunocompromised people is distinct and different from the conversation around boosters.
