One of the simplest and most reliable ways to protect your parents' health is vaccination. Yet when you actually try to find out which vaccines are needed, when, where, and at what cost, the system can feel overwhelmingly complicated. In 2026, both Korea and the United States have expanded their senior vaccination support programs. Whether you are a family member living in the U.S. or in Korea, getting familiar with the latest policies in each country in advance will help you make sure no vaccination window is missed.
🇰🇷 Korea Under the 2026 National Immunization Program, adults aged 65 and older can receive the influenza (flu) vaccine free of charge at designated medical institutions nationwide. The 2025–2026 seasonal influenza national immunization program ran from September 22, 2025, through April 30, 2026. Starting this season, the vaccine was switched from a quadrivalent (4-valent) to a trivalent (3-valent) formulation. The Korea Disease Control and Prevention Agency (질병관리청) has confirmed there is no difference in preventive efficacy or safety, and this is a global measure in line with WHO recommendations. Adults aged 65 and older are also eligible to receive the 23-valent pneumococcal polysaccharide vaccine (PPSV23) once, free of charge, at a nearby contracted medical institution. Seniors with underlying health conditions are advised to consult with the examining physician in advance regarding vaccine selection and timing.
🇰🇷 Korea A notable change to watch in 2026 is the expansion of shingles vaccine support. Coverage for the shingles vaccine had previously varied depending on each local government's budget, but under strong government initiative, the country is moving toward making it available nationwide at no cost. At present, however, implementation still differs by region. For example, Suwon City supports the vaccine cost for residents aged 65 and older born in even-numbered years, while requiring the individual to pay a portion of the administration fee out of pocket. Seniors who are recipients of basic livelihood benefits (기초생활수급자) or near-poverty households (차상위계층) can receive the vaccination entirely free at their local public health center (보건소). Before getting vaccinated, we recommend confirming your eligibility at your local public health center or through the 질병관리청 예방접종 도우미 website (nip.kdca.go.kr).
🇰🇷 Korea COVID-19 vaccination for adults aged 65 and older is also covered under national support. The 질병관리청 recommends that seniors aged 65 and older receive the flu and COVID-19 vaccines at the same visit, and vaccination sites can be searched on the 예방접종 도우미 website regardless of your registered address. After vaccination, it is safest to remain at the medical facility for 20 to 30 minutes to monitor for any adverse reactions before going home.
🇺🇸 U.S. In the United States, Medicare Part B covers flu, pneumococcal, COVID-19, and hepatitis B (for high-risk individuals) vaccines with no out-of-pocket cost. The updated COVID-19 vaccines for the 2025–2026 season (Moderna, Pfizer-BioNTech, Novavax) are also available at no cost to Part B enrollees. Beginning January 1, 2026, all Medicare Part D plan enrollees (including Medicare Advantage) are required to have access to all adult vaccines recommended by ACIP (Advisory Committee on Immunization Practices) at a $0 cost share. The shingles vaccine Shingrix and the RSV vaccine are also available at no additional cost through Part D plans.
🇺🇸 U.S. Regarding the RSV vaccine, the CDC recommends vaccination for all adults aged 75 and older, as well as for adults aged 60 to 74 who are at high risk for severe illness. Medicare covers the full cost through Part D. Note that the RSV vaccine is not an annual vaccine — if you have already received it, an additional dose is not needed — so it is important to check your vaccination history first. Also, depending on your Medicare plan, the RSV vaccine may be billed under Part B or Part D, so confirming the billing method with the medical facility before your appointment can help you avoid unexpected costs.
Both countries have programs in place, but they share one important common point: you won't receive the benefits unless you actively seek them out. 🇰🇷 Korea The 보건복지부 (Ministry of Health and Welfare) emphasizes that national immunization program benefits are not provided automatically without a direct application, and encourages people to inquire at their local 주민센터 (community service center) or 보건소. 🇺🇸 U.S. Medicare enrollees who are not signed up for a Part D plan may also face out-of-pocket costs for certain vaccines such as shingles and RSV, so it is a good idea to review your plan enrollment and coverage scope every year.
