Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.
Do not receive a "live" vaccine while using Stelara, and avoid coming into contact with anyone who has recently received a live vaccine. There is a chance that the virus could be passed on to you. Live vaccines include measles, mumps, rubella (MMR), rotavirus, typhoid, yellow fever, varicella (chickenpox), zoster (shingles), and nasal flu (influenza) vaccine.
BCG vaccine should not be given for at least 1 year after you receive your last dose of Stelara.
Non-live vaccines (including flu shots) may not work as well during your treatment, and may not fully protect you from disease. Make sure you are current on all vaccines before you begin treatment with this medicine.
