This is not a debate. This is not a question. This is not in doubt. In any way. 4 million deaths worldwide are prevented by childhood vaccination every year. For over 2 centuries, people have been vaccinated against deadly diseases, ever since the world’s first vaccine was devised against smallpox. Vaccines now help protect against more than 20 diseases, from pneumonia to cervical cancer and Ebola; and in just the last 30 years, child deaths have declined by over 50%, thanks in large part to vaccines.
