hi! i had dog scratches last December 2015 and immediately given the 4-6 shot i think of rabipur and a shot of ERIG, the whole vaccination process lasted until January 2016. last night, my brother-in-law s playful dog had approached my hand and its teeth somehow had pressed on my hand. it did not bleed or was not cut, but there was a small dot of blood visible on the area i mentioned like a blood clot. computing from the time i had my finished my last vaccine, it s now 2years and 2 months.should i get booster shots?
