Yesterday i went to take Anti-rabies vaccination.I saw that sister posted there using the same intra-dermal syringe.She has already started aspirating the fluid,then i ask her to change the syringe.What she did she changes the syringe accordingly but she injected the fluid what she had already aspirated into a vial.And from the same vial she aspirate and give me intra-dermal injection.I d'ont know the HIV status of the previous patient.Should i start pep?
