Did your child get scratched by an alley cat? And at the same time did your child receive no rabies shots? 15 days ago, my daughter got scratched by a cat, now we're getting injections for rabies. We received one dose of ACVD. The scratch is very small and healed quickly with no trace, not deep, but they put it at a third degree. Now I read on a forum that you need another immunoglobulins from tetanus, but immunoglobulins are antibodies (blood) from another person. It's very risky to put in and not put in. Can the antibodies be tested? My head is spinning.
