Hip: "I was rather hoping that someone here with Lyme disease would have read the backgound material and could have summarized it." Seems to me people have been trying to summarize points for you for over a day now, but you keep insisting on more.
Hip: " A vaccine is about preventing a disease in the first place." In part, but it's not necessarily just that. It is also about making money. The Lymerix vaccine story was relevant because of the potential conflicts of interest involved, but also because of the firestorm caused when some recipients reported adverse side effects. Those complaints had an impact on the revenue stream. The product was pulled from the market.
Hip: "I still can see no financial motivation on the part of the IDSA for refusing to accept the existence of chronic Lyme." Can you see the financial motivation on the part of Insurance carriers for refusing to accept the existence of chronic Lyme? Yes?
Hip: "...the major issue for Lyme patients: who accepts and who does not accept the existence of chronic Lyme." For many, this is certainly a major issue. But it is far from being the only issue. Also disputed is the very definition of what constitutes a positive diagnosis of Lyme disease - for instance, whether IgM positive patients a year into the disease constitute Lyme disease, or whether two IgG bands (or three or four) that are specific to Bb are sufficient. Remember; even the IDSA acknowledges that once Borrelia disseminates, it is harder to treat. So every time someone is infected and they don't receive treatment, there is a chance the disease will progress and cause damage.
Then there is the poor characterization of Lyme disease symptom clusters, the dismissive or minimizing qualifications. Let's not forget, too, the rigid adherence to diagnostic criteria that were designed 20 years ago for surveillance purposes, not clinical evaluations. The screening mechanism that by some accounts is no more accurate than a toss of a coin.
There is also the lack of large and meaningful controlled studies into the efficacy of long term treatments. Or the tendency on behalf of mainstream Lyme enthusiasts to embrace circular logic in their bid to justify the efficacy of current diagnostics. Ditto for current treatments.
Need more? Well, there is the appalling risk doctors willing to treat outside of IDSA protocol assume each and every day - risks of being investigated by state medical boards, of losing their license to practice medicine.
Then there is what the CDC promotes as post-treatment Lyme disease syndrome, not to be confused with chronic Lyme. The latter should represent continued infection. PTLDS presupposes successful treatment, and the absence of Bb in the patient. With PTLDS, abx therapy is not recommended. So, if you get colored with the PTLDS brush, and you actually DO still have Bb, you are out of luck.
There is the whole co-infection debacle, but I'm going to stop here. I hope you will concede there is a lot more on the table for Lyme patients than "just" the dispute over chronic Lyme. Also, if you are going to reference "chronic Lyme" , you may wish to acquaint your self with how the IDSA/CDC define the term - it's not the same as most of the rest of the world uses it.
