RWE study of the US’ largest COVID-19 database shows that COVID-19 vaccine protected the majority of cancer patients
13 May 2022
- The study used one of the largest COVID-19 real world databases in the world, with over 12.5 million patients, including 4.5 million COVID-19 patients.
- Key findings from the analysis were:
- The risk of breakthrough infection was reduced after the second vaccine dose for all cancers.
- Patients with hematologic cancers, or blood cancers, including leukemia, multiple myeloma and lymphoma, were at a higher risk of breakthrough COVID; those with blood cancers had a greater risk than solid cancers.
- The Moderna vaccine was more effective than the Pfizer vaccine for protecting patients with hematologic cancers, especially patients with multiple myeloma.
