“This study has highlighted that patients arguably most in need of protection against shingles cannot currently benefit from vaccination,” Harriet Forbes, the study’s lead researcher from the London School of Hygiene & Topical Medicine, said. “The vaccine is live and there are concerns that giving it to patients with severe immunosuppression may cause a shingles episode. Alternative risk reduction strategies among these patients, for example the use of alternative vaccines, would help those at greatest risk of this disease and its complications.”
Other conditions shown to give patients an increased risk of shingles included rheumatoid arthritis, inflammatory bowel disease and chronic obstructive pulmonary disease. Asthma, chronic kidney disease, type 1 diabetes and depression were also shown to give patients a slight increase in shingles risk.
