October is when respiratory season ramps up around Puget Sound. Here is how to sort out which vaccines older adults are commonly advised to get, where Medicare Part B and Part D each pay, and how to plan for a parent in a care home.

Cool, damp weather pushes people indoors from October through March, and respiratory viruses spread more easily in shared spaces. For adults over 65, flu, COVID-19 and RSV can lead to hospital stays, and a hospital stay can start a chain of problems: deconditioning, delirium, a rehab stay and sometimes a move to a higher level of care. Prevention is one of the cheaper ways to protect a parent's independence.
Vaccine recommendations change from year to year, so treat this article as a planning guide, not medical advice. Ask your parent's primary care provider or pharmacist which shots are due, and check the Washington State Department of Health and CDC adult immunization schedules for the current guidance.
Influenza: an annual shot is widely recommended for adults 65 and older, and there are versions designed for this age group, including high-dose and adjuvanted options. Early to mid-fall is a common time to get it. COVID-19: updated vaccines have been offered each fall, and older adults have generally been among the groups encouraged to stay current. RSV: a one-time vaccine has been recommended for the oldest adults and for some younger older adults with conditions such as heart or lung disease, so ask about eligibility.
Shingles (Shingrix) is a two-dose series for adults 50 and older. Pneumococcal vaccines protect against pneumonia and bloodstream infections, and Tdap or Td boosters keep tetanus protection current. Many seniors are missing one or more of these simply because nobody asked. A short list brought to the next appointment is often all it takes.
Original Medicare Part B generally covers the flu shot, the COVID-19 vaccine and pneumococcal shots with no cost sharing when you use a provider who accepts Medicare. Vaccines that fall under Part D, such as shingles, RSV and Tdap, are covered through a prescription drug plan, and recent federal rules removed out-of-pocket costs for most recommended adult vaccines under Part D. Coverage details still vary by plan.
The practical tip: use an in-network pharmacy and bring both your Medicare and drug plan cards. If a pharmacy says a Part D vaccine will cost money, ask whether it is in network and whether the doctor's office can bill instead. Medicare Advantage members should check their plan's network rules. If paying for premiums and cost sharing is a strain, see our guide to Washington's Medicare Savings Programs.
Across King, Snohomish and Pierce counties, most large pharmacy chains and many independent pharmacies give flu and COVID-19 shots, often without an appointment. Primary care clinics, health systems such as UW Medicine, MultiCare and Providence, and local health departments are other options. For a parent who cannot easily leave the house, ask the in-home care agency, the pharmacy or the clinic about home or mobile vaccination; availability varies.
Call ahead to confirm that the pharmacy gives the specific vaccine and age group you need, and allow time for the 15-minute wait afterward. Bring a photo of the vaccine record if you have one, or ask the pharmacist to look it up in the state immunization registry.
Adult family homes, assisted living residences and nursing homes in Washington each have their own approach to vaccine clinics, and most coordinate with a pharmacy partner or visiting nurse. When touring, ask how vaccines are offered to residents, how consent is handled, and what the policy is for staff and visitors during respiratory season. Residents with dementia may need a family member or legal decision-maker to give consent, so keep the power of attorney for health care paperwork current.
Also ask what happens during an outbreak: how families are notified, whether visits change, and how symptoms are monitored. A clear answer is a good sign of an organized home. If you have concerns about a facility's response, you can contact the Long-Term Care Ombudsman or DSHS Residential Care Services.
Make a list of the vaccines your parent has had and when. Bring it to the next primary care visit and ask what is due this fall. Confirm coverage with the pharmacy before the shot, schedule flu and COVID-19 early in the season, and set a reminder for second doses such as Shingrix. If you are the caregiver, ask about your own vaccines too; a healthy caregiver is part of the care plan.
