Formaldehyde Sensitivity

"My site has several articles by the Nobel Laureate Alexis Carrel regarding injections of highly dilute poisons, similar to formaldehyde in Salk vaccine, which was 1:4000 concentration. Carrel injected carcinogens at 1:5000 to 1:250000 and caused reliably, cancer in chickens."---Jim West

''A snippet from my microbiology textbook states "Formaldehyde's extreme toxicity (it is classified as a carcinogen) and irritating effects on the skin and mucous membranes greatly limit its clinical usefulness" ... So then WHY is it useful in vaccines?''
