Hi and thank you so much for this query. I am so sorry to hear about what you experienced trying to help the stray dog. With you well vaccinated against rabies, there is no fear of contracting the disease again and there should be no need to get a new rabies injection now. How is your tetanus vaccination status if it is not up to date, please try to updat it. Also, deep scratch wounds may require antibiotics for treatment. Do not hesitate to contact your doctors on this. I hope this helps. I wish you well. Thanks for using our services and feel free to request for more information if need be.
