My cousin (age 28) has recently vaccinated in uphc, while she enters into vaccination room, she didn't notice that, whether the nurse has taken the new injection for vaccination or not. The nurse kept the injection in hand and vaccinated to my cousin. Now, my cousin is too afraid about it. Her concern is, if the nurse vaccinated her with already used injection? If so, will my cousin will be affected by hiv? She is daily afraid of it. It makes her so depress. Pls someone help on this matter.
