Corticosteroids, especially in high dosages, may increase the risk of serious adverse events following live varicella and zoster vaccination. Studies have shown that patients receiving corticosteroids after vaccination are more prone to severe infectious complications, highlighting the importance of monitoring for such risks in clinical practice.
Corticosteroids, when given in high dosages, have long been recognized as a risk factor for severe infection with wild-type varicella-zoster virus in both children and adults. The goal of this review is to assess the degree to which both low-dosage and high-dosage corticosteroids contribute to serious adverse events (SAEs) following live varicella vaccination and live zoster vaccination. To this end, we examined multiple published reports of SAEs following varicella vaccination (Varivax(TM)) and zoster vaccination (Zostavax(TM)). We observed that five of eight viral SAEs following varicella vaccination, including two deaths, occurred in children receiving corticosteroids, while one of three fatal viral SAEs following live zoster vaccination occurred in an adult being treated with low-dosage prednisone. The latter death after live zoster vaccination occurred in a 70 year-old man with rheumatoid arthritis, being treated with prednisone 10 mg daily. Thus, corticosteroids contributed to more severe infectious complications in subjects immunized with each of the two live virus vaccines. Further, when we surveyed the rheumatology literature as well as individual case reports, we documented examples where daily dosages of 7.5-20 mg prednisone were associated with increased rates of severe wild-type varicella-zoster virus infections in children and adults.
