The guidelines also conditionally recommend that all patients aged 65 and older who have rheumatic or musculoskeletal diseases receive the high-dose or adjuvanted flu vaccine, regardless of whether they are taking immunosuppressive medication. Another new conditional recommendation is to give multiple vaccinations to patients on the same day, rather than give individual vaccines on different days.
The guidelines make conditional recommendations regarding flu and nonlive attenuated vaccines for those taking methotrexate, rituximab, or glucocorticoids. Methotrexate should be held for 2 weeks after flu vaccination as long as disease activity allows it, but patients who are taking methotrexate should continue taking it for any other nonlive attenuated vaccinations.
“Non-rheumatology providers, such as general pediatricians and internists, are encouraged to give the influenza vaccination and then consult with the patient’s rheumatology provider about holding methotrexate to avoid a missed vaccination opportunity,” the guidelines state.
Patients taking rituximab should receive the flu vaccine on schedule and continue taking rituximab. However, for these patients, the guidelines recommend to “delay any subsequent rituximab dosing for at least two weeks after influenza vaccination if disease activity allows.”
“Because of the relatively short time period between the rollout of the influenza vaccine and its season, we can’t always wait to time the B-cell depletion dosage,” Dr. Kim said. “Also, it is not always easy to synchronize the patient’s B-cell depletion dosing schedule to the influenza vaccine rollout. Thus, we now just recommend getting the influenza vaccine regardless of the patient’s last B-cell depletion dosage despite its known strong attenuation of optimal immune responses.”
For other nonlive attenuated vaccines, providers should time vaccination for when the next rituximab dose is due and then hold the drug for at least 2 weeks thereafter, providing time for the B cells to mount a response before rituximab depletes B cells again.
Patients taking less than 20 mg of prednisone daily should still receive the flu vaccine and other nonlive attenuated vaccines. Those taking 20 mg or more of prednisone each day should still receive the flu vaccine, but other vaccines should be deferred until their dose of glucocorticoids has been tapered down to less than 20 mg daily.
Patients taking all other immunosuppressive medications should continue taking them for the flu vaccine and other nonlive attenuated vaccinations, but it is conditionally recommended that live attenuated vaccines be deferred. For any patient with a rheumatic and musculoskeletal disease, regardless of disease activity, it is conditionally recommended that all routine nonlive attenuated vaccines be administered.
For live attenuated virus vaccines, the ACR provides a chart on which immunosuppressive medications to hold and for how long. Glucocorticoids, methotrexate, azathioprine, leflunomide, mycophenolate mofetil, calcineurin inhibitors, and oral cyclophosphamide should all be held 4 weeks before and 4 weeks after administration of a live attenuated vaccine. For those taking JAK inhibitors, the medication should be halted 1 week before administration of a live vaccine and should continue to be withheld for 4 weeks after.
For most other biologics, the ACR recommends holding the medication for one dosing interval before the live vaccine and 4 weeks thereafter. The main exception is rituximab, which should be held for 6 months before a live vaccine and then for 4 more weeks thereafter.
For patients receiving intravenous immunoglobulin, the drug should be held for 8-11 months before they are administered a live attenuated vaccine, depending on the dosage, and then 4 weeks after vaccination, regardless of dosage.
To reassure people with rheumatic disease who may have anxiety or concerns about receiving immunizations, whether taking immunosuppressive medication or not, Dr. Kim said it’s important to provide lots of education to patients.
“Fear and emotion have replaced facts, and data as a leading factor in decision-making, as seen with COVID-19,” Dr. Kim said. “The reality is that a small minority of people will have any issues with most vaccines, which include disease flares, adverse events, or acquisition of an autoimmune disease. We are not saying there is zero risk, rather, that the risk is quite small. This is where shared decision-making between the health care provider and the patient must be done effectively to enable the patient to properly weigh risk versus benefit.”
Dr. Kim has relationships with GlaxoSmithKline, Aurinia Pharmaceuticals, Kypha, Pfizer, Alexion Pharmaceuticals, AstraZeneca, Exagen Diagnostics, and Foghorn Therapeutics.
