20 Science Questions
that U.S. presidential candidates were asked in 2016
My administration would support vaccine science and safety by creating a stronger adverse reaction reporting system, and by funding research assessing the long term health risks that may be associated with the large number of vaccinations that are now being given to children in the United States compared to the number that had been given to previous generations of U.S. children.
Fewer vaccinations given slightly later in life (not during the first six months of life when the infant’s immune system is not well developed) might be safer for children with an underlying susceptibility for autoimmune disease. Forcing all children to get vaccinations against minor illnesses may provide some herd immunity to the group, and at the same time it may be causing encephalitis in a few susceptible children which has been known to lead to autism like symptoms.
Children with known allergies or autoimmune problems should be allowed to have their parents decline the full schedule of vaccinations. There are more than four times as many shots given to children now than children received in the 1970’s in the United States.
Vaccinations are important but having good health in the first place is also important. Adequate sanitation and nutrition can help make a population less at risk to catching an infection during an epidemic. Funding for clean water infrastructure can help prevent a variety of diseases, not just exotic ones.
Funding for evaluating the use of calcium chloride as an adjuvant instead of aluminum is a priority to help protect the children with difficulty detoxifying heavy metals and possibly help prevent some children from developing neuro-developmental disorders.
Between January and August of 2016 there have been 52 cases of measles reported. In 2015 there was a total of 189 cases of measles reported. 
For perspective, not to say causal relationship but just to compare the size of the problems, in 2015 the rate of autism diagnosis was estimated to have reached 1 in 45 children. In 2012 it was 1 in 68, in 2000 it was 1 in 150. [2, 3]
The 2015 rate of 1 in 45 children would suggest that roughly 448,919 of the children who were under five years old at the time of the 2010 census may have developed autism by now. 
It is sad that 52 people had measles in 2016 so far, and it is also sad, possibly more sad, that 448, 919 children born between the year 2010 to 1996 may have gone on to develop autism spectrum disorder by now.
Based on my reading of available medical research the problem that may underlie development of autism is related to prenatal health and nutrient deficiencies in combination with more toxins in the environment and food supply. A deficiency of vitamin D or vitamin D enzymes, and deficiency of iodine, zinc, folate, magnesium, and possibly vitamin B 12 and B 6, may all make it difficult for a pregnant woman to detoxify and protect her expectant infant from an excess of formaldehyde and other toxins (the herbicide glyphosate is known to inhibit vitamin D enzymes) or heavy metals such as aluminum, mercury or lead.
Vaccinations are important but so is having a functioning and well nourished immune system. Excessive numbers of vaccinations may be over-activating the allergic portion of the immune system and leaving more children with allergies and more children and adults with autoimmune disorders. 
Vaccinations are important but their use should be limited to the most dangerous diseases and allow children to get sick and recover naturally from milder illnesses such as chickenpox. The natural immunity derived from getting sick and recovering naturally strengthens both the antigen/antibody portion of the immune system that vaccinations are designed to enhance and also strengthens the white blood cell portion of the immune system.
White blood cells are the cells that are actually responsible for identifying and killing any infected or malformed cells using the antigen/antibody system as a identifying label. The antibody acts as a label that shows the white blood cell which cells are infected or malformed or foreign microbes, and the white blood cell can then put the cell to death by apoptosis by giving it a little blast of energy from magnesium, and then the white blood cell engulfs and removes the remains of the infected, malformed, or foreign cell.
