For people who have had vaccine related injury please consider treating for underlying mycoplasma infection through contamination (expert biologist Professor Garth Nicholson states “vaccines often have these but are not tested for because it is too expensive” https://www.youtube.com/watch?v=9ZN-kXZMzqU 36; 27. These microbes cause long term CHRONIC AILMENTS THAT SHOW UP LONG AFTER A VACCINE IS GIVEN. IF there is a contamination. Ailments can be pain, fatigue or neurological in type.
What can you do if you feel chronically ill after a vaccine. I would say treat for potential mycoplasma infections. See Prof Garth Nicholsons paper from pg 19 onwards. “Since most mycoplasmas and ureaplasmas are generally sensitive to tetracyclines (doxycycline, minocycline, among others), with some notable exceptions, these should be considered for frontline treatment, and quinolones (ciprofloxacin, sparfloxacin, levofloxacin, ofloxacin, among others)    , as alternative treatment.”There are many types of herbal extract mixtures and formulations that have been used in patients with pathogenic mycoplasma infections . These include those that contain, in no particular order, cordeceps (Cordycepsspp.),Chinese skullcap (Scutellaria sinensis), Chinese senega root (Polygala tenufolia),kudzu root (Pueraria lobata), isatis (Isatis indigotica and other species), houttuynia (Houttuynia cordata) olive leaf (Olea europaea), berberine* (Berberisspp.), uva ursi (Arctostaphylos uva-ursi), pomegranate (Punica granatum), anogeissus (Anogeissus leiocarpus), tea tree (Melaleuca alternifolia), noni (Morindacitrifolia), among others. Buhner  has carefully discussed the available evidence justifying the use of these herbal formulations in patients with mycoplasmal infections.
I would personally recommend andrographis paniculatus found from health shops, scutellaria bacailensis and *hydrastsis goldenseal tinctures! In addition to medium term antibiotic treatment.
