Govt estimates that 5,000 children from 4.8 million need to be revaccinated

A scandal over fake vaccines given to children prompted angry and confused parents to physically attack a doctor in the Indonesian capital in a sign of deep-seated problems in the country's health system.

Since last month, vials filled with saline solution and antibiotics have been discovered at 37 hospitals and clinics in nine cities, according to the Food and Drug Agency. So far, 23 people have been arrested, including three doctors. The number of affected children is still being investigated but could be significant in a country of more than 250 million people.
