Quiz: How much do you know about vaccinations?

Updated

Immunization is one of the most cost-effective means to address global health threats. Vaccines have nearly eliminated diseases such as polio, a devastating illness that killed half-a-million people a year during the 20th century. The number of deaths from tetanus, mumps and malaria have also been drastically reduced. 

Within the last 15 years, vaccine programs have saved approximately six million lives. And, even better, vaccines are relatively inexpensive – it only costs $23 to vaccinate a child against seven major diseases. 

The bottom line is: Vaccines save lives. How much do you know about them?
