Influenza Vaccine Rates in Adults with Psoriasis

J Invest Dermatol; 2019 Feb; Noe, Shin, et al

Patients with rheumatoid arthritis (RA) are more likely to receive a flu vaccine than patients with psoriasis, and this difference is magnified in people aged <50 years. This according to a recent study that aimed to measure the rate of seasonal influenza vaccination in psoriasis patients in the US and compare it to the rate of influenza vaccination in patients with other chronic diseases—RA and hypertension. Researchers performed a cohort study using US-based administrative and commercial claims data, including all adults (aged ≥18 years) with a diagnosis of psoriasis, RA, or chronic hypertension requiring oral antihypertensive therapy. They found:

  • There were 17,078 patients with psoriasis, 21,832 with RA, and 496,972 with chronic hypertension requiring oral therapy.
  • Adults with RA were approximately 10% more likely to receive a flu vaccination than psoriasis patients, after controlling for age, sex, and treatment with systemic therapy; however, the likelihood of receiving a flu vaccination varied by age.
  • Patients with psoriasis were younger than those with RA and chronic hypertension.
  • As expected, 73% of patients with RA were female compared to 49.8% and 50.6% of patients with psoriasis and chronic hypertension, respectively.
