but that's why i thought the paper i linked would be of interest - as its findings were that boiling had no ill effects on the vaccine effectiveness - vs lower temperatures or other methods of sterilisation. And boiling would be much easier to control in a DIY setting.
Yes it is interesting, though since the paper is from 1915, it's not clear whether its results would stand up to modern scrutiny. I wanted to find more current information about bacterial inactivation for vaccines, but there is surprisingly little to be found.
Doing bacterial inactivation is critically important for safety too: some professional microbiologists I spoke to who regularly work with such biosafety level 2 pathogens said that if some bacteria were still alive after the heat treatment, and you placed these under your tongue, they could potentially cause a serious lung infection (pneumonia) requiring hospitalization.
So making a mucosal vaccine would be risky for those without microbiology background. You ned to use certain tests to ensure all your bacteria are really dead. That's in part why our project was halted, as it could be a risk to ME/CFS patients. I would not want to place online details of my experiments if they carried a risk.
Also, it's not clear whether we need to remove the bacterial toxins. This can be done, but it requires a lab centrifuge machine. Many common bacterial toxins, including LPS, are lethal to humans in amounts as low as 1 or 2 micrograms, if they get into the systemic blood circulation. Some bacterial toxins are heat stable, and can survive 100°C. I am not sure if autoclave temps of around 121°C will destroy all of them. Some Staphylococcus toxins are particularly heat stable. By contrast, some toxins are quite heat labile, and are destroyed by heat.
Sometimes women die from toxic shock syndrome, which occurs when a tiny amount of a Staphylococcus toxin called TSST-1 from sanitary towel use gets into the bloodstream via tiny lesions in the vagina. So this indicates that bacterial toxins on the mucosal could be dangerous if they get into the blood via lesions.
Mucosal vaccines applied sublingual and intravaginally are proven to have strong effects in the urinary tract:
Uromune (MV140) is one bacterial vaccine we found which is applied daily as a sublingual spray, and greatly reduces the recurrence of UTIs in those who suffer from repeated urinary infections. It contains 4 common UTI bacteria that are heat killed.
There are at least 5 published studies on Uromune, some
here and
here. Unfortunately Uromune is only
obtainable under doctor's supervision, and history of UTIs. However, Cipher found some alternatives
here.
Dr Markov also prescribes his autovaccine patients a mucosal bacterial product:
IRS-19.
mucosal application of vaccines
i think we need to understand how these auto-vaccines actually work
This is a good paper showing how application of antigens on one mucous membrane can induce an IgA antibody response on other mucous membranes in the body. As you can see from table 2 of the paper, copied below, there is an immune interconnectivity of the mucosa, and the sublingual mucosa are strongly interconnected with other mucosal.
So that's why applying bacterial antigens sublingual can have potent immune effects in the urinary tract.
The same table as above can be found in this paper:
Buccal and sublingual vaccine delivery, in
table 1.
Note that "blood" in the above table is equated to "systemic response" in the Buccal and sublingual vaccine delivery paper table 1. So "blood" should be read as a "systemic immune response".
