They are more vulnerable to the severe effects of the flu or come into contact more often with this highly contagious virus.
"We think the recommendations we have right now (are) a good start," Butler said. "Universal campaigns are quite challenging and expensive.
"We have 53 countries in our region that all have different recommendations based on different studies and evidence, and the depth of evidence in Europe right now is pretty limited in terms of flu vaccines. We would need more evidence that more than these six key, target high-risk groups that are prioritized can benefit. "
Online speculation says the U.S. call for general vaccination is merely a plot by drug companies to make a big profit.
So it's not just the as you would call it, "uneducated." There are many well if not better educated folks, making national policies who have determined there is limited benefit to vaccinating everyone.
