Which vaccines are covered for all Medicare Part B enrollees?

Medicare Part B provides coverage for certain vaccines that are deemed essential for patient health, particularly among older adults and those with specific medical conditions. Among these vaccines, both the influenza vaccine and the pneumococcal vaccines are included in the coverage.

The influenza vaccine is offered annually to help prevent seasonal flu, which can lead to serious health complications, especially in the elderly. The pneumococcal vaccines, which help protect against pneumonia and other infections caused by Streptococcus pneumoniae bacteria, are also crucial as they significantly reduce the risk of infections that can be severe in older adults.

While Td/Tdap vaccines are important for preventing tetanus and diphtheria and are generally recommended, they are not universally covered by Medicare Part B for all enrollees. The herpes zoster vaccine (HZV) is also not covered under Medicare Part B for all beneficiaries, as coverage may vary based on specific criteria and age.

Thus, the correct answer highlights the comprehensive coverage of both the influenza and pneumococcal vaccines for all Medicare Part B enrollees, which reflects public health priorities aimed at protecting vulnerable populations from prevalent and potentially deadly diseases.
