But again even with Tetanus it is still freely admitted that you can see get it even if you are vaccinated. Look at the language the institutions use, it clearly indicates that:
It's not stated that you 'will not get tetanus'. Only that it's 'unlikely'. Which is basically legalese for saying, "well, this thing
appears to work, but don't count on it and certainly don't blame us if it doesn't".
Either it works or it doesn't. Which is it? I find it quite perplexing that people just overlook this whilst simultaneously defending, rigorously, that vaccines do work. If it works then it should work. That is the foundation of science; the reproducibility of a result based on a hypothesis that you're testing against. If people are still getting these conditions despite being vaccinated, then clearly there is something wrong with our understanding somewhere and it is simply a matter of belief that vaccines 'work'.
Study shows tetanus shots needed every 30 years, not every 10
There you have an expert admitting, clearly, that once again the pharmaceutical industry has literally just made it up. People have been led to believe they need it every 10 years, and here is an expert just openly admitting there isn't even the data to justify that decision. Sounds awfully like covid vaccines doesn't it.
I'd wager money the actual reason Tetanus incidence has decreased is again not because of vaccination but because of steadily improving diet, and that susceptibility and severity is directly related to deficiency in one or more key nutrients. A quick google search seems to indicate Vitamin A and C.
