Under what circumstances anti rabies vaccine rabipur can cause rabies? if it is mishandled or not stored properly can it cause rabies?

The company that makes the vaccine has quality controls that check the lots-so there are no concerns of that. Rabies can be tricky though, as the incubation time (time from bite to disease) can be very long -even more than one year. Best to see an Infectious Diseases doc if Qs
