Immune response found to decrease to COVID-19 vaccines among organ transplant recipients and others on immunosuppressive drug regimens, as per findings in a new editorial by Peter Heeger, Christian Larsen, and Dorry Segev who discuss recent evidences – including a recent Science Immunology study by Hector Rincon-Arevalo and colleagues.

The authors note that this presents challenges at both the individual and population levels, since current vaccine protocols may not provide adequate protection to immunosuppressed patients – who could, in turn, become reservoirs for new and dangerous variants of the virus.
