There has never been a vaccine that is 100% effective. It greatly decreases your chances of contracting the virus....as well as greatly reduces the risk of your having detrimental complications to your long term health. Taking steps towards easy and simple preventative healthcare saves time for Caregivers to give to patients suffering from conditions you cant as easily prevent.
The less chance you have of getting it, the less chance you have of spreading it. It's all a numbers game. No politics, just science.
