In 07/04/2018 while visiting a zoo in Bangladesh I have been scratched by a monkey (macaca mulatta).The scratch was in my right hand thumb which was not deep and covers only 2mm area. I was given rabies shot on days 0,3 and 7.My last dose of vaccine is due in 28 days.After giving rabies vaccine I have persistent flu and headache for 8 days (I have problems of maxillary sinusitis,a nasal polyp, chronic hepatitis b also).If I found the monkey healthy on day 27 do I need to take my last shot?
