Compared to other developed countries, the U.S. has the most aggressive vaccination schedule during the first year of life, both in terms of number of shots and timing. Sadly, the U.S. also has a higher infant mortality rate than any of the world's other wealthy countries - even higher than some of the poorest nations.
A study reported by the National Institute of Health found significant correlation between the number of vaccines and the infant mortality rates of countries. For example, Canada requires almost as many vaccines as the U.S. and also has a high infant mortality rate. In contrast, Japan and Sweden have the lowest number of vaccines and also have the lowest infant mortality rates in the world.
The study states that "despite the United States spending more per capita on health care than any other country, 33 nations have better infant mortality rates. It also states that "the relative position of the United States in comparison to countries with the lowest infant mortality rates appears to be worsening.” This means that as the vaccine schedule has increased, the US has experienced worsening infant mortality.
In addition, that same study reported a connection between Sudden Infant Death Syndrome (S.I.D.S.) and the vaccines routinely given in the U.S. at two and four months. This is the time frame that most S.I.D.S. deaths occur and a reported 61% of babies had received vaccines within 12 hours to 2 weeks before death.
The National Institute of Health (NIH) is the government body that oversees all other health authorities in the US, including the CDC. However, the CDC appears to have ignored this NIH study since it continues to add vaccines to the schedule even as infant death rates continue to increase.
