I am HCW,during vaccination camp for hepatitis B., I got needle stick injury after I.m injection while recapping it as it pierces the cover,however at that time syringe was not attached to needle,I have read on your previous reply that if syringe is not attached to needle there is no risk for hiv,....my concern is that while recapping the thrust at base of needle usually causes some fluid to come out at tip,can it go inside me while prick and infect me.,however prick was superficial with single drop of blood came out on pressing it.... .i will be obliged for your reply
