Across the globe, more than 100 million children per year now are immunized against vaccine-preventable diseases. But 6 of these infections still claim hundreds of thousands of lives, most of them children before the age of 5. Deaths from hepatitis B are usually in adults, but most had contracted the infection in early life when infection is much more likely to result in chronic disease.
Can you rank these 6 still-deadly diseases from highest to lowest in terms of number of deaths?
♦ Diphtheria-tetanus-pertussis combined
♦ Hepatitis B
