A member asked:

Why 2nd dose of anti rabies vaccine given 7 days later? give full reasons?

A doctor has provided 1 answer

Vaccines: Most vaccines require more than1 dose when you start them. The first dose primes the immune response and the second dose therefore gets an inhanced response. The length of time between the 2 doses varies some based on the vaccine. When u have your first flu vaccine you need 2 then each year the vaccines are similar enough that you just remind your immune system with one dose fine tuned to that yr
