Influenza vaccine

The government approves to inject influenza vaccine and propagate it. I have no common about it, because there are two conditions to be discussed. The flu vaccine is produced by the DNA or RNA which is got from last year flu. Because of that, sometimes the vaccine isn’t effective absolutely. For babies, their resistance against disease is weak, so I think that it is necessary that they are injected by flu vaccine. For children, I think it isn’t. According to the child’s state of health, parents decide whether take their child to inject flu vaccine. That can decrease the waste of medical resource. The programs of TV propagate parents to take their children to inject influenza vaccine are not necessary for someone.
