Children aged 6–59 months;
Adults aged ≥50 years;
Persons with chronic pulmonary (including asthma), cardiovascular (excluding isolated hypertension), renal, hepatic, neurologic, hematologic, or metabolic disorders (including diabetes mellitus);
Persons who are immunocompromised due to any cause, (including medications or HIV infection);
Women who are or will be pregnant during the influenza season;
Children and adolescents (aged 6 months through 18 years) receiving aspirin- or salicylate-containing medications and who might be at risk for Reye syndrome;
Residents of nursing homes and other long-term care facilities;
American Indians/Alaska Natives;
Persons who are extremely obese (BMI ≥40); and
Caregivers and contacts of those at risk:
Health care personnel in inpatient and outpatient care settings, medical emergency-response workers, employees of nursing home and long-term care facilities who have contact with patients or residents, and students in these professions who will have contact with patients;
Household contacts and caregivers of children aged ≤59 months (i.e., <5 years), particularly contacts of children aged <6 months, and adults aged ≥50 years; and
Household contacts and caregivers of persons with medical conditions that put them at high risk of severe complications from influenza.
