False. The flu shot is an important vaccine for elderly patients, but it's not the only vaccine they need. Elderly patients may also need vaccines to protect against pneumonia, shingles, and other diseases. The Centers for Disease Control and Prevention (CDC) recommends that all adults aged 65 years and older receive the pneumococcal vaccine, which can protect against pneumococcal disease, including pneumonia. The CDC also recommends that adults aged 50 years and older receive the shingles vaccine, which can help prevent shingles and its complications.
