With rates of autism in the United States reaching near-epidemic proportions, efforts to identify autism’s causes continue. Researchers are working diligently to discover why the U.S. has one of the highest rates of autism in the world while small less-developed nations like Cuba have a much lower incidence. While there has been much discussion whether differences in vaccination rates between the two countries may account for the disparity in autism prevalence, there are some theories that exist.
The Cuban childhood vaccination schedule includes protection against 13 diseases in 11 vaccines in a total of 34 doses while the United States requires 11 vaccines in 36 doses. About 99 percent of Cuban children are fully vaccinated versus about 85 percent of American children. With two very similar vaccination schedules it makes one question whether vaccinations themselves are causing the alarming rise in autism in the U.S. or if it is due to something else?
There is a marked difference in the two nations’ autism rates. Cuba reports a rate of only 0.00168 percent while the U.S. rate stands at 1.13 percent. Both nations vaccinate for similar diseases such as polio and measles so the idea that vaccinations somehow cause autism would seem to be discounted.
Where do you think the difference may lay?
