Global vaccination efforts have saved an estimated 154 million lives, including 101 million infants, a new study led by the World Health Organization (WHO) shows.
Immunization has contributed more to the health and survival of newborns than any other medical advance, researchers concluded.
The measles vaccine has had the most significant impact on reducing infant deaths, accounting for 60% (94 million) of the lives saved by immunization, researchers said.
Overall, vaccines have saved the equivalent of six lives every minute of every year for the past half-century, the WHO study says.
