Preserving access to preventive services by clarifying state authority and definitions

This bill keeps preventive care affordable in Washington. The health department can issue vaccine guidance. Most health plans must cover state‑recommended vaccines and proven screenings with no in‑network copays; if no in‑network provider exists, out‑of‑network must be covered. It updates funding so insurers and administrators help pay for children’s vaccines. HSA plans may use minimal cost sharing. No one is required to get vaccinated. The bill takes effect immediately.
