Meningococcal Vaccination Rates Among People With a New Diagnosis of HIV Infection in the US

In the United States, individuals with HIV infection have been recommended to receive a 2-dose series of the meningococcal A, C, W, Y (MenACWY) vaccine since 2016 owing to their increased risk of meningococcal disease.

To examine uptake and time to receipt of the MenACWY vaccine among people with a new diagnosis of HIV.

This cohort study used health insurance data from the US Optum Research Database from January 1, 2016, through March 31, 2018, to retrospectively identify 1208 individuals aged 2 years or older with 1 or more inpatient claim or 2 or more outpatient claims evidencing a new diagnosis of HIV infection and with continuous insurance enrollment for 12 or more months before and 6 or more months after diagnosis. Follow-up was 6 to 33 months. Statistical analysis was conducted from March 7, 2019, to January 5, 2022.

Receipt of the MenACWY vaccine.

The coprimary outcomes were uptake and time to receipt of 1 or more doses of the MenACWY vaccine after a new HIV diagnosis. Secondary outcomes included uptake and time to receipt of 2 or more doses of the MenACWY vaccine. Vaccination uptake and receipt were estimated by Kaplan-Meier analysis; factors associated with receipt of 1 or more doses of the MenACWY vaccine were identified with multivariable Cox proportional hazards regression analysis.

Of 1208 individuals eligible for vaccination (1024 male patients [84.8%]; mean [SD] age, 38.8 [12.5] years; 35 [2.9%] Asian; 273 [22.6%] Black; 204 [16.9%] Hispanic; 442 [36.6%] White), 16.3% were estimated to have received a first dose of the MenACWY vaccine in the 2 years after a new HIV diagnosis. Among individuals who received a first dose, at 1 year or more of enrollment after the first dose, 66.2% were estimated to have received a second dose within 1 year of the first dose. Factors statistically significantly associated with uptake of the MenACWY vaccine included receipt of a pneumococcal vaccine (hazard ratio [HR], 23.03; 95% CI, 13.93-38.09), attendance at a well-care visit (HR, 3.67; 95% CI, 1.11-12.12), West or Midwest geographic region (West: HR, 2.24; 95% CI, 1.44-3.47; Midwest: HR, 1.78; 95% CI, 1.16-2.71), and male sex (HR, 2.72; 95% CI, 1.18-6.26), whereas age of 56 years or older was significantly associated with reduced uptake of the MenACWY vaccine (HR, 0.42; 95% CI, 0.18-0.97).

This cohort study suggests that MenACWY vaccine uptake among people with a new diagnosis of HIV was low, highlighting the need to educate patients and clinicians about the recommendations for conditions such as HIV infection that increase the risk of meningococcal disease among high-risk populations.
