Rabies can strike even after vaccination; prompt care prevents it

Rabies can develop despite vaccination, but this is extremely rare; failures typically result from delayed care, improper wound treatment, or missed vaccine doses. Post-exposure prophylaxis combines immediate 15-minute wound washing, rabies immunoglobulin for unvaccinated people, and a vaccine series; all are essential, and incomplete or improper administration can lead to failure. Previously vaccinated people usually receive two booster doses instead of immunoglobulin after a bite, yet every potential exposure still requires medical evaluation.
