About 2 weeks ago I had a exposure with a street worker had a condom break just before I finished , I was going crazy because all I kept thinking about was HIV or Hep B !!! I went to the clinic next day and I got vaccinated For HEP B , Iv had a 2nd Dose 10 days After And my 3rd one in 2 weeks time (accelerated Vaccine ) Does This Help Before Becoming Infected ? I will never in my life do this again !!!!!!
