I think that the current thinking is that AZT is safe to use for about 3 weeks but that liver toxicity starts to become a problem with longer term use. This may be long enough to get control of the stomatitis, though. The only source of lactoferrin that I know of is Emerson Ecologics: 800-654-4432.
Understanding the difference between vaccines, vaccinations, and immunizations can be tricky. Below is an easy guide that explains how these terms are used: A vaccine is a product that produces immunity from a disease and can be administered through needle injections, by mouth, or by aerosol. A vaccination is the injection of a killed or weakened organism that produces immunity in the body against that organism.
There are two types of vaccines, inactivated and live, and these present different indications after administration. Vaccinations are the act of administering the vaccine that produces immunity in the body against the organism. Immunization is the process by which one becomes protected from a disease. Vaccines cause immunization, and sometimes diseases can also trigger immunization after the individual recovers from the disease.
