Now that I have your attention. There are many reasons to terminate a pregnancy. Some perhaps more legitimate than others. The following explains it much better than I. Quoted from an ultrasound technician.
Comparing a woman's access to a medical abortion and taking a vaccine is comparing apples to oranges. Now if you want to compare dropping your trousers and taking a shit in the middle of a crowded stadium vs using the porta john, restroom etc. to taking or not taking the vaccine your a little closer to reality. At its basic level, your decision to take a shit in a crowded place (your body your choice) doesn't just effect you. It effects those in your immediate area and those that may come in contact with you and the shit you left behind.
