Which vaccine is the first to be routinely recommended after exposure to prevent a disease?
Quick Answer
The rabies vaccine is famous for post-exposure prophylaxis, which can prevent rabies after a bite if given promptly. It is usually given with rabies immunoglobulin for certain exposures.
The Full Story
Rabies vaccination is unusual because it is often used after exposure, not just before it. If given quickly after a bite or scratch from a potentially rabid animal, along with proper wound care and sometimes rabies immunoglobulin, it can prevent the disease. Rabies is almost always fatal once symptoms start, which is why rapid post-exposure treatment is so important. This makes rabies vaccine one of the most time-critical medical interventions in infectious disease.
