Percentage of clients1 with HIV infection who have received influenza vaccination within the measurement 

period2

Numerator: Number of HIV-infected clients who received influenza vaccination within this time frame 

Denominator:

privileges3

 at least once in the measurement period 

Patient 

Exclusions: 1. Patients allergic to vaccine components 

Data Elements:

Basis for Selection and Placement in Group 3: 

Influenza viruses cause disease among all age groups. While rates of infection are highest among children, 

rates of serious illness and death are highest among persons aged > 65 years, children less than 2 years and 

persons of any age who have medical conditions that place them at increased risk for complications of 

influenza, including HIV.5 

Influenza vaccination is the most effective method for preventing influenza and its severe complications. 

Vaccination has been demonstrated to produce substantial antibody titers against influenza among vaccinated 

HIV-infected persons who have minimal AIDS-related symptoms and high CD4+ T-lymphocyte cell counts.6 

The measure is placed in Group 3 because it overlaps and focuses on similar aspects of care (vaccination) that 

were previously captured in measures included in Group 2. In addition, the data collection process is more

complex because of the timing of the vaccination. 

US Public Health Guidelines: 

“Annual vaccination against influenza is recommended for....adults and children who have 

immunosuppression (including immunosuppression caused by medications or by human immunodeficiency 

virus).”7
