Is vaccinations’ effectiveness preventing disease or causing it?
Some food for thought:
1. Multiple vaccination has been shown, according to the Arthur Research Foundation in Arizona, to exhaust and diminish your immune system strength by 60%. This is backed by a completely independent study in Israel that vaccination indeed diminishes the immune system strength.

2. An epidemic of smallpox killed 45,000 people immediately after a mass smallpox vaccination program began in 1867 in England. Between 1871 and 1880, following the vaccination program, the incidence of smallpox escalated from 28 to 46 per 100,000.

3. Epidemiologists in general have noted that there was a decrease of 95% in the incidence of all the acute infectious diseases because of better hygiene between 1911 and 1945, before mass vaccinations began. Death rates from polio had reduced dramatically also by the early 1950’s in the USA before the introduction of the vaccine in 1955. But there was a 50% increase from 1957 to 1958, and an 80% increase between 1958 and 1959! The scientific assessment of Jonas Salk himself, the inventor of the vaccine, was the vaccine itself was the cause of nearly all of the increased polio from the 1950’s through the 1960’s.

Would you agree if one states they may actually cause the disease they were meant to prevent?
