Prednisone, a corticosteroid, can impact how your body responds to vaccines. The effect varies depending on the type of vaccine and the prednisone dose.
Live Attenuated Vaccines
Live attenuated vaccines, like the measles, mumps, rubella (MMR) vaccine and the varicella (chickenpox) vaccine, use weakened versions of the virus. Prednisone can reduce the effectiveness of these vaccines. High doses of prednisone, especially taken for an extended period, pose a greater risk of reducing the immune response. Consider delaying these vaccines if possible while on high-dose prednisone.
Inactivated Vaccines
Inactivated vaccines, such as the flu shot and polio vaccine, use killed viruses or parts of viruses. Prednisone’s impact on these vaccines is generally less significant than on live attenuated vaccines. A low to moderate dose of prednisone usually won’t prevent immune response. However, high doses or prolonged use may still slightly reduce efficacy. Discuss timing with your doctor.
Other Vaccine Types
- Recombinant vaccines: These vaccines, like the Hepatitis B vaccine, use genetically engineered components of the virus. Prednisone’s effect on these is also usually minimal, but higher doses may warrant discussion with your healthcare provider. Toxoid vaccines: These, such as the tetanus and diphtheria vaccines, use inactivated toxins. The influence of prednisone on the immune response to toxoid vaccines is typically modest. MRNA vaccines: These vaccines, like some COVID-19 vaccines, introduce mRNA to trigger an immune response. Data on the interaction with prednisone is still emerging, but the impact is likely less than with live attenuated vaccines. Consultation with your physician is advised.
Recommendations
Always consult your doctor or other healthcare provider before receiving any vaccine while taking prednisone. They can assess your individual circumstances and recommend the best course of action. Discuss the type of vaccine you’re receiving, the dosage and duration of your prednisone treatment, and any other relevant medical conditions. This information is crucial for determining the appropriate timing and approach. Be aware that your doctor may advise delaying vaccination until your prednisone treatment ends or the dose is lowered. Your doctor may decide the benefits of the vaccine still outweigh any risks in some situations.
