Doctors across the nation are alarmed that skepticism fueled by rising anti-science sentiment and medical mistrust is increasingly reaching beyond vaccines to other safe and routine care for babies.

One common thread that ties together anti-vaccine views and growing sentiments against other protective measures for newborns is the fallacy that natural is always better than artificial, said Dr. David Hill, a Seattle pediatrician and researcher.

“Nature will allow 1 in 5 human infants to die in the first year of life,” Hill said, “which is why generations of scientists and doctors have worked to bring that number way, way down.”
