Which vaccination should patients with heart failure be up-to-date with annually?

• A. Hepatitis B
• B. Influenza
• C. Measles-Mumps-Rubella
• D. Varicella

Answer: (B)

Influenza vaccination is particularly important for people with heart failure because a flu infection can trigger a severe illness that worsens heart function, leading to hospitalization or even death. Getting the flu shot every year updates protection to match the strains circulating in the coming season, and this yearly update is necessary because the influenza virus changes frequently. For adults with chronic heart failure, the vaccine reduces the risk of influenza-related complications and decompensation of heart failure.

The other vaccines listed are not administered annually as a routine for heart failure patients. Hepatitis B is given in a multi-dose series based on risk, not as a yearly update. Measles–Mumps–Rubella and Varicella are part of childhood vaccination schedules or catch-up schedules, and are not required annually for HF management.
