Hi
If your child is vaccinated till 1 and half year upto date no need for TT injection as the primary
DPT and booster DPT contain TT. And comvac 5 is not required. You should start Antirabies
vaccination immediately if that dog is received no vaccination or insufficient vaccination. You should start taking antirabies injections according to schedule and you should observe the dog for 10 days for any illness or death and in this duration you will complete 0 3 7 doses of schedule. After 10 days the dog is healthy and alive you can skip the remaining two doses after discussing with your doctor. So go for a
second opinion near by you and get the proper medical advise
