Serologic screening and infectious disease consultation (IDC): Indicated in heart, lung, liver (HLL) solid organ transplants (SOT) for measles, mumps, rubella, and varicella.

Despite the relatively high IDC rate, patients' screened numbers for MMR IgG levels were low. Results pointed out the need for MMR protocol-driven serologic screening as well as for VZV and IDC prior to transplantation to increase vaccination rates.
