[Cost-effectiveness analysis on two different measles immunization strategies]

To seek the most economic and effective strategy in measles elimination in China, data of cost - effectiveness was analyzed to compare two different strategies of measles immunization (mass campaign and 2 - dose schedule) based on the data of population, economy and epidemiological features of measles in Henan province.

DALY was used as the measurement of effectiveness. Taking period from 1997 to 2020, the cost - effectiveness ratio (CER) was defined as the cost difference between mass campaign and 2 - dose schedule divided by the decline of DALYs if 2 - dose schedule had been substituted by mass campaign.

Along with the increment of time, CER showed a descending trend then the mass campaign will have positive benefits after year 2013.

Mass campaign is more cost - effective than 2 - dose schedule.
