Influenza Vaccination: Primary Prevention 286,383 community-dwelling members aged >65 years of 3 large managed-care organizations evaluated for 1-2 yrs Influenza vaccination reduces adverse CV events Nichol KL et al. NEJM 2003;348:1322-32
Influenza Vaccination Patients with cardiovascular disease should receive the influenza vaccination annually
