Europe is experiencing outbreaks of measles,mumps,polio and several other diseases thought to be totally controlled. This has two causes the immigration of large numbers of non- vaccinated children and adults and the growing number of the antivaxxers. The latter ignore scientific information and maintain that vaccines are harmful but ignore the fact that so many children and adults have not caught these diseases.The USA is having a similar experience from the increased number of the antivaxxers. They get misinformation and take it as valid without the proper research. How sad.
