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.
An annual seasonal flu vaccine (either the flu shot or the nasal spray flu vaccine) is the best way to reduce the chances that you will get seasonal flu and spread it to others. When more people get vaccinated against the flu, less flu can spread through that community.
