Judith,
If I understand your question, it is:
Is the vaccine completely safe in regards to interacting with an active virus should the patient become infected after being vaccinated?
Is that close?
James
I think so. Can a retrovirus (HIV) combine genetic material with the flu virus, or vice versa, to make a “hybrid” virus? Again, my vocuabulary (and knowledge base) is insufficient.
In other words, the H1N1 vaccine was given to HIV positive children, and didn’t “take” very well. Is there any possibility that HIV+ patients who are given the H1N1 vaccine will have the two “recombine” genetic material to make (for example) an HIV virus that can be spread by aerosol?
