More than 4.8 million children in 58 out of 63 cities and provinces nationwide received free measles and rubella shots in the first phase of the national vaccination campaign, announced Ministry of Public Health on November 10.

The ministry has asked provincial and district authorities to draw lessons from the first phase in order to timely improve on the work in later phases.

At the same time, they must ensure sufficient supply of vaccines and necessary materials as well as guarantee the quality and safety of the vaccines.

The three-phase vaccination campaign has been implemented from September 2014 to February 2015, targeting about 23 million children between the ages of 1-14 throughout the nation, increasing the vaccination rate for children of this age group to 95 percent.-VNA
