Merck introduced its measles vaccine in 1963, claiming the vaccine would convey lifelong immunity equivalent to a natural infection, with health officials promising that 55% vaccine coverage would produce "herd immunity" sufficient to eradicate measles by 1967.
Leading scientists of the day, including the world's preeminent bacteriologist, Sir Graham Wilson and Harvard Virologist John Enders, who first isolated measles, warned against introducing a vaccine unless it provided lifelong immunity. Measles, they cautioned, would rebound with increased virulence and mortality as the vaccine forced the evolution of more virulent strains and shifted outbreaks away from children—biologically evolved to handle measles—to the elderly who could die from pneumonia, and young infants now unequipped with maternal immunity.
A 1984 Johns Hopkins University modeling study predicted that Merck's population-wide experiment would increase measles outbreaks by 2050, (when the last generation subject to natural immunity died off,) compared to the pre-vaccine era. This is exactly what has happened. Merck's vaccine, with a growing failure rate has been incapable of abolishing the disease. Vaccine failure has left millions of adult Californians effectively unvaccinated. And 79% of people affected by measles in this year's California outbreak were adults.
When eradication predictably didn't materialize and measles attacked fully-vaccinated populations, Merck simply moved the goalpost saying that herd immunity required 75% vaccination, then 85%, then 95%, then 98%. And now 99%. To distract the world's citizens from its failed vaccine, Merck started blaming "anti-vaxxers." (The Vaccine Safety Movement)
Now California's bought or brain-dead lawmakers are proposing to "fix" Merck's vaccine failure problem by punishing 4,000 vulnerable children with medical exemptions. In an act of legislative savagery, Democratic politicians propose to forcibly vaccinate children whose doctors have told them that a vaccine could kill or severely injure them. SB276 will not fix the measles outbreak or solve the problem of vaccine failure, it will only reward a corrupt company for a defective product.
