If you don’t believe in vaccines for whatever reason, leading organizations have united to affirm vaccine safety amid rising misinformation and declining trust. The coalition of thirty-four scientific and medical organizations is led by the American Association of Immunologists and American College of Physicians. One of the leaders says vaccines are one of the greatest achievements of biomedical research. Stephen Jameson also says ensuring continued support for science is essential to protecting public health and combating emerging infectious diseases. The tangible consequences of declining vaccination rates are currently in the news—with the ongoing measles outbreak and the tragic death of a child in Texas, the first measles death in this country in a decade.\
