Question: when was mumpsvax administered in 1960
I found the following answer on Google: Sample vaccinations schedules discussed by the World Health Organization show a developed country using a schedule which extends over the first five years of a child's life and uses vaccines which cost over $700 including administration costs while a developing country uses a schedule providing vaccines in the first 9 months of life and costing only $25.
Is that a correct answer? Yes or no.
