Do you mean "fully vaccinated" meaning up-to-date on all ACIP‑recommended vaccines for adults (i.e., having received every vaccine recommended for their age/risk groups)? Or do you mean a specific vaccine (influenza, Tdap, HPV, zoster, pneumococcal, etc.)?

If you mean up-to-date on all routinely recommended adult vaccines, estimates are very low — on the order of a few percent (roughly 2–5%, commonly cited ≈3%). If you mean a single vaccine, the percentage varies widely by vaccine (for example, seasonal influenza coverage is around 40–50% in recent years, Tdap roughly 25–40%, shingles and pneumococcal coverages are higher in older adults). Which definition/source/timeframe do you want?
