My pet dog who is vaccinated himself against rabbies 7-8 months ago bit me on my hand though it's a very small bite like only a drop of blood came out then I went for the vaccination next day(within 24 hrs after the bite) in government hospital and the 2nd shot was scheduled after 3 days which is today but they ran out of stock so told me to come tomorrow in the morning so is it fine to get it on the 4th day ?
