Which fall vaccines older adults need, whether Medicare Part B or D pays, and where to get shots in San Diego County, including at home.
By Patricia Nguyen, CDP · October 06, 2026
Every October, the families I talk with in San Diego County ask the same thing: which shots does my parent actually need this season, and who pays for them? It is a fair question. Adults 65 and older are more likely to be hospitalized from influenza, COVID-19 and respiratory syncytial virus (RSV), and for someone living in assisted living or memory care, one outbreak can move through a whole community quickly.
The good news is that Medicare covers most recommended vaccines with little or no cost to you, and San Diego has plenty of places to get them. The key is knowing which part of Medicare pays for which shot, because the answer determines where your parent should go.
Under Original Medicare, Part B covers the seasonal flu shot, COVID-19 vaccines, and pneumococcal (pneumonia) vaccines, with no copay when the provider accepts Medicare assignment. Part D, the prescription drug benefit, covers most other recommended adult vaccines, including shingles (Shingrix) and RSV. Since the Inflation Reduction Act took effect, Part D plans must cover those recommended vaccines with no cost sharing.
That split matters at the counter. A pharmacy can usually bill a flu or COVID shot straight to Medicare Part B, but an RSV or shingles shot must be billed to the Part D or Medicare Advantage drug plan. If your parent has a Medicare Advantage plan, check the plan card and ask whether the pharmacy is in network before you go.
Ask your parent's doctor which shots are due. Recommendations depend on age, health conditions and prior vaccination history, and they change from season to season, so confirm current guidance with the physician or the CDC rather than relying on last year's routine.
Most older adults will find the easiest option is their regular doctor or a major pharmacy. Primary care offices, Sharp, Scripps, UC San Diego Health, Kaiser and Palomar clinics all offer seasonal shots to established patients, and national pharmacy chains take walk-ins in nearly every San Diego neighborhood.
If cost or insurance is a barrier, County of San Diego Public Health Services runs public health centers that offer vaccines, and the free 2-1-1 San Diego line can point you to current clinic locations and hours. Federally qualified health centers also serve Medi-Cal members and people without coverage on a sliding scale.
For a parent who cannot easily leave home, ask about mobile or in-home vaccination. Many home health agencies and some pharmacies will vaccinate at home, and Aging & Independence Services at 800-339-4661 can help families identify local options for homebound seniors.
When you tour a community, ask how it handles vaccinations. Good communities offer on-site flu and COVID clinics each fall, track which residents have been vaccinated, and have a plan for staff vaccination and for outbreak response. You can also look at a licensed residential care facility's record on the California Community Care Licensing Division site at ccld.dss.ca.gov to see its inspection history.
If your parent has dementia, you or the person holding health care power of attorney will usually give consent. Keep a written record of every shot and its date so the next facility, hospital or doctor can see it. Veterans enrolled at VA San Diego Healthcare System in La Jolla can also receive vaccines through VA clinics at no charge.
Start by asking the doctor which vaccines are due. Next, confirm whether each one bills to Part B or Part D. Then pick a location, schedule it, and add the dates to a shared family record. Try to get the flu shot by the end of October, since protection takes about two weeks to build and flu season in Southern California can begin early.
Vaccines are one layer of protection. Handwashing, staying home when sick, and asking visitors to postpone a visit if they have symptoms still matter, especially in group living. If your parent develops fever, new confusion or trouble breathing, call the doctor promptly instead of waiting.
