If you’re on medications that dampen your immune system, questions about vaccines can feel more confusing than they used to. Which ones are safe? Which ones need extra planning? What about the ones your primary care doctor mentions in passing at a physical? For many patients on biologics or DMARDs, vaccines aren’t just routine care. They’re an important layer of protection.
Understanding the basics can help you feel more confident about the conversations you have with your care team, and less anxious about doing the right thing to protect your health.
Why Vaccines Matter More on These Medications
Immunosuppressants work by calming an overactive immune system. That’s exactly what you want for controlling autoimmune disease, but it can also mean your body has a harder time fighting off certain infections. Vaccines help fill that gap by preparing your immune system in advance, so it can respond more quickly if you’re exposed.
Staying up to date on recommended vaccines is one of the most straightforward things you can do to reduce your infection risk while staying on treatment.
Live vs. Non-Live Vaccines
The most important distinction to know is between live vaccines and non-live vaccines.
Non-live (inactivated) vaccines use a killed or partial version of a virus or bacteria. They can’t cause the disease they protect against, and they’re generally safe for people on immunosuppressants. Common examples include flu shots (the injection, not the nasal spray), Tdap, pneumonia vaccines, and shingles (Shingrix).
Live vaccines contain a weakened version of the actual virus. In healthy people they’re very safe, but in people with suppressed immune systems they can occasionally cause the disease itself. Live vaccines are often either avoided, given only after careful discussion, or timed around medication schedules. Examples include MMR (measles, mumps, rubella), the nasal-spray flu vaccine, yellow fever, and the older live shingles vaccine (Zostavax).
Vaccines Most Commonly Recommended
Your care team will tailor recommendations to your specific medications and history, but a few vaccines come up often:
Annual flu shot: Recommended for essentially everyone on immunosuppressants. The injectable version is the safe choice.
Pneumonia vaccines: Often recommended earlier than the standard age cutoffs for people on immunosuppressants.
Shingrix (shingles): A non-live vaccine given in two doses, often recommended for people on biologics or DMARDs.
COVID-19 vaccines and boosters: Recommended per current guidance, with timing sometimes adjusted based on medications.
Tdap: The standard adult booster to protect against tetanus, diphtheria, and pertussis.
Timing Matters
When possible, vaccines are given before starting immunosuppressive treatment, because your immune system tends to respond more strongly then. If you’re already on medication, that’s okay too, but timing may be adjusted around your dosing schedule for the best response.
Your care team may also want to check antibody levels for certain vaccines to make sure your body has responded well.
Practical Tips
- Keep a running list of the vaccines you’ve received and when, and share it with your care team
- Ask your rheumatologist before getting any live vaccine, including travel-related ones
- Get your annual flu shot early in the season, ideally in early fall
- Coordinate vaccine timing with your medication schedule if your care team recommends it
- Let your other providers, like primary care and pharmacists, know about your immunosuppressive medications
A Simple Way to Stay Protected
Vaccines are one of the easiest, safest ways to add a layer of protection while you manage your condition. Most people on biologics and DMARDs can safely receive nearly all the vaccines their care team recommends, with a little planning around live vaccines.
If you’re due for a vaccine and you’re not sure if it’s safe for you, ask before you go in. A quick message to your care team can save you a trip and make sure the timing works with your treatment plan.
