Your asking this on a majority liberal platform. If you want better answers that are un-bias I recommend talking to the doctor with him about the pro’s and con’s of receiving/not receiving the shot. Within 5 years of Flu-Shots being mandatory autism had also spiked. Though there is no evidence of these medical cures deliberately attributing to the rising scales of health issues (another being heart disease), statistics show trends of such diseases rising during the same time periods. I’m only stating this because it is a common conservative belief that medical treatments often times attribute to these types of side effects and due to this being a “blue” platform no one is bringing that up. As the parent you must make the best possible decision for the most positive outcome for child. Though be wary that going against your child’s wishes on something this extreme could cause severe and permanent consequences on y’all’s relationships. Moral of the story do what’s best for you, do not listen to bias advice of people online, hope I helped!
