About 20 days back i was sitting behind someone on scooter going on city road, when suddenly a dog crossed us closeby. i was wearing slippers . i didn't focus on this much at that time ... but since past 4-5 days it has started bothering me that what if the dog had scratched me with nails and i didn't notice or feel anything ... i am feeling very paranoid.. shoul i take 5 injections now ? or is it too late... please help.. also are there any major side effects of anti rabies vaccines if i take them
