A member asked:

How doctors explain the long incubation period (>1 year) of rabies , can pep vaccination still be effective after 9 months of possible exposure?

A doctor has provided 1 answer

Rabies is tricky: Rabies is known for a wide variation in the incubation period. The average is 3 weeks to 3 months for infection to take hold. About 5% of cases occur 1 year after exposure. The longest case on record is 19 years. Experts don't know exactly why this is-but it probably has to do with the virus strain, other viral properties, the patient (how strong their immune system is) etc. YES-I agree with PEP!
