NCCN released this morning significant revisions from its Advisory Committee on COVID-19 Vaccination and Pre-exposure Prophylaxis to include recommendations on the recently-approved bivalent vaccines as well as how to protect children with cancer. The new, evidence-based, expert consensus-formulated summary on cancer and COVID-19 vaccination and prevention is available on the NCCN website nccn.org/docs/default-sourc...
Included in the recommendations are definition of what it means to be “immunocompromised” and how that can affect both eligibility for vaccine boosters and their scheduling. This guidance is categorized based on a patient’s tumor and/or treatment regimen as well as by the type of vaccine.
New information in the updated guidance includes:
Immunosuppressed people who have previously received a three-dose primary series and boosting through prior recommendations are now eligible to receive one of the bivalent boosters if they are 12-years-old or older for Pfizer, or at least 18-years-old for Moderna. This has been shown to improve immune response against Omicron strains in people with full immune system capacity. The committee supports this recent approval but cautions they are still awaiting data on bivalent booster effectiveness in immunocompromised people.
In addition to the new recommendations, the NCCN has reiterated earlier COVID-19 prevention advice such as:
Not recommending antibody testing, outside of a research study;
Recommending boosters for everyone with a hematologic malignancy regardless of whether they are in active treatment;
Preferring mRNA vaccination in most situations;
Endorsing the option of mix-and-matching the two mRNA vaccines;
Re-vaccinating after a patient undergoes hematopoietic cell transplantation or engineered cellular therapy (e.g. chimeric antigen receptor [CAR] T-cell therapy);
Vaccines are considered safe for people undergoing immunotherapy;
Vaccination status shouldn’t impact participation in clinical trials; and
Using monoclonal antibodies (tixagevimab plus cilgavimab) as prophylaxis (in addition to vaccination) in selected immunocompromised patients at risk for COVID-19 complications
