Vaccination

In some cases, ME/CFS appears after vaccination. Dr John Chia has found that around 1.5% of his ME/CFS patients appeared to have their disease triggered by vaccination.<a href="http://cid.oxfordjournals.org/content/36/5/671.full.pdf" rel="nofollow" target="blank" >1</a>Dr Charles Shepherd says that the vaccine most commonly linked to triggering ME/CFS is hepatitis B. To a much lesser extent, influenza, BCG, tetanus, meningitis, MMR, polio, hepatitis A and typhoid vaccines have also been anecdotally linked to triggering ME/CFS.<a href="http://forums.phoenixrising.me/index.php?threads/science-to-patients-talking-me-exercise-and-the-mitochondria-with-dr-charles-shepherd.29488/#post-450521" rel="nofollow" target="blank" >1</a> <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC1488229/" target="_blank" rel="nofollow" >2</a>

The causal factor in vaccine-triggered disease may be the adjuvant in the vaccine, which Dr Yehuda Shoenfeld says can instigate a condition he has dubbed autoimmune (auto-inflammatory) syndrome induced by adjuvants (ASIA).<a href="http://www.ncbi.nlm.nih.gov/pubmed/20708902" rel="nofollow" target="blank" >1</a> Adjuvants that can precipitate ASIA include: aluminum hydroxide, squalene and silicone.<a href="http://www.ncbi.nlm.nih.gov/pubmed/23557271" rel="nofollow" target="blank" >1</a> One study examining how ME/CFS or fibromyalgia can arise after hepatitis B vaccination indicated that these diseases can both arise as specific manifestations of ASIA.<a href="http://www.ncbi.nlm.nih.gov/pubmed/25427994/" rel="nofollow" target="_blank" >1</a>

In 2013 the Federal US Court ruled that hepatitis B vaccine caused ME/CFS in one patient, and awarded the patient $1.1 million plus lifetime medical expenses.<a href="http://forums.phoenixrising.me/index.php?threads/federal-us-court-rules-hepatitis-b-vaccine-caused-chronic-fatigue-syndrome.24663/" target="_blank" rel="nofollow" >1</a>
