Whenever I read posts on here about flu vaccines...I sometimes see a reply how the seasonal flu vaccines is new every year or every other year...well it's new due to the different strain of virus they put in the vaccines. ..right? My questions are this:
How does the medical manufacturer know what strain of flu virus that's going to go around for that year?
And what if different people have different strain?
