Cant pregnant bcz of Rubella Infection.

We had a baby in 2016 but she was too weak and after her tests we got to know that she was rubella infected. We tried hard but couldn't save her and she died after 7 months. That time doctor advised us to take proper medication and vaccine for my wife. We consulted doctor and my wife had taken rubella treatment for 3 months after that doctor said that we can attempt for baby. We did that and we had twins but after 6 months in 2nd stage ultrasound report we got that our babies have some problem. We went to Dr. Singh in ghaziabad where we got to know that babies are again rubella infected because of which we had to abort them. Again we waited for an year and last year we again visited to doctor where she vaccinated my wife again with 3 months treatment but because of corona we don't visit to hospital for next 9 months and recently last week we went to hospital where Dr. Taken my wife's torch test where Dr. Is saying that still the problem is existing. Please help in this.
