OBJECTIVES: Vaccination is critical for preventing infection-related morbidity and mortality in older adults. This study assessed the trends in vaccine utilization among Medicare part D beneficiaries aged ≥65 in the United States.
METHODS: A retrospective analysis was conducted using the Centers for Medicare and Medicaid Services Medicare Provider Utilization and Payment Data: Part D Prescriber public use files. Utilization of vaccines covered by Part D, namely, Tetanus, Diphtheria, Pertussis (Tdap/Td), Hepatitis A & B, Hepatitis A Virus, Hepatitis B Virus, Haemophilus Influenzae Type B (HIB), Human Papillomavirus (HPV), Japanese Encephalitis, Measles, Mumps, and Rubella (MMR), Meningococcal, Poliomyelitis, Rabies, Typhoid, Yellow Fever, Chicken Pox, and Shingles were assessed. Data from 2013 to 2022 was used to describe the number and proportion of beneficiaries receiving the vaccines over time.
RESULTS: During the ten-year study period, a total of 24.8 million vaccines were received in pharmacies. The number of vaccinations in pharmacies increased from 1.6 million in 2013 to 3.5 million in 2022, a rise of 127%. Vaccinations increased significantly in 2019 and 2020, with about 4 million vaccinations each year. The vaccination for Shingles was the highest, rising from 1.3 million (4.5%) in 2013 to 2.5 million (6.0%) in 2022, with particularly high vaccination (9.5%) in 2019 reaching about 3.7 million vaccinations. Tdap vaccination in pharmacies increased from 229,968 (0.8%) in 2013 to 885,559 (2.1%) in 2022, a rise of 285%. Similarly, the Hepatitis vaccination also increased from 15,273 (0.05%) to 60,578 (0.14%) over the same period, with a notable rise observed in 2019 (184,235 (0.48%)).
CONCLUSIONS: Shingles and Tdap vaccines were frequently administered vaccines in pharmacies for older adults, emphasizing the need to expand vaccination outreach for other vaccines. Future research should explore the impact of these vaccination trends in pharmacies on health outcomes and healthcare resource utilization.
