Well, influenza vaccine can prevent some cases of influenza, but there is surprisingly little evidence of the effect on serious disease.

"There was insufficient information available to assess school absenteeism due to very low-certainty evidence from one study. We identified no data on parental working time lost, hospitalisation, fever, or nausea."

The real issue is that she clearly Don't know the contents of the Cochrane summary of the state of the current research.

In healthy children of adults we don't have the evidence. For individuals influenza vaccine may be beneficial. It's a complicated issue.

Now for the vast majority of vaccines, it is another story, and there is no evidence that the influenza vaccine is harmful or unsafe.
