Why didn't the village inform you to get the fourth injection?

Because the epidemic prevention department's policy is to be willing to fight, people who are willing to fight will pay attention to relevant news information on TV and mobile phones or online inquiries. After those who are willing to take the fourth injection go to the vaccination service department, the staff enthusiastically take the initiative to complete the fourth injection for you. Only in this way can we show that we are willing to fight all the way.
