This measles vaccination campaign is indeed full of doubts and uncertainties. Let's just talk about one of these doubts: what is the necessity of this vaccination campaign? Even if we want to achieve the WHO's goal of "eliminating measles by 2012", there is no need to carry out a nationwide, one-size-fits-all ten-day blitz right now! Why can't we follow the "regular vaccination", "phased and batch vaccination", or "supplementary vaccination based on the specific circumstances of children"? Fellow citizens, in response to this measles vaccination incident, we must listen to opinions from all sides, not believe in rumors, and know how to discern.
