From what I understand there are already 3 antiviral treatments being introduced right now in pill form. That being set they can help if they are taken early on after symptoms appear and again aren't 100% effective. In addition they cannot be used by pregnant women. As with every disease prevention is always the better approach and vaccines offer that.
