Which part of Medicare is responsible for covering vaccines?

Part D of Medicare is responsible for covering vaccines, specifically the recommended vaccines that may not be covered under other parts of Medicare. Under Part D, the coverage generally includes immunizations that protect against diseases like influenza, pneumonia, and hepatitis B. This ensures that beneficiaries have access to necessary vaccinations that can help prevent serious health issues.

Parts A and B have different focuses; Part A primarily covers inpatient hospital care, while Part B covers outpatient services, including medical supplies, preventative services, and outpatient care, but not all vaccines. Part C, also known as Medicare Advantage, includes benefits from both Part A and Part B and may offer additional coverage, but it doesn't specifically have a standalone policy for vaccines. Part D is distinct in its role of providing coverage tailored to prescription medications and certain vaccines, thus making it the correct answer in the context of health services related to immunization.
