Thanks for your question and concern. It is really unfortunate to know that you are affected with genital herpes infection. As your doctor said, you may use Resan. Resan is a drug which imitates tumour antigens. It will make the body start producing anti-tumor immunity in people, once it is administered. It is usually used in cancer patients or people who are suspected to affect with tumor, to suppress malignancy chances. It cannot be used as an immunity booster, but can be used along with cancer treatment. Similarly, it is not sufficient to increase immunity power of body on to prevent an outbreak of herpes symptoms. It is recommended to follow a healthy diet and mind to maintain a healthy physique, even after getting affected with STDs. HSV, is not curable and your doctor is right with that. But medications are available to reduce visible symptoms. Hope my answer helps. Take care.
