My son age 23 just returned from his doctor, John Chia, (1-310-784-5880) an infectious disease doctor in LA, who thinks Ampligen is ineffective. Regarding valtrex, my son almost died on Valtrex given by another doctor. Dr. Chia believes in testing for the actual virus you have and treating that virus. His research is with entero viruses but is familiar with all. He uses interferon, immunoglobulin, anti-virals and herbs. He experiments with them in various combinations. I have more information if anyone is interested.
