You have a lot of power over this. Simply act as if we live in a world without vaccines. For most diseases, we do in fact live in that world.
By the way, we've found viruses that cause heart disease and obesity. There are no vaccines for these. Many viruses also cause cancer, not just the ones we have vaccines for.
Protecting against this is all about your day-by-day personal choices. Do you choose the restaurant with reusable metal forks, or the one that provides plastic ones in individual plastic bags? Do you choose the fruit salad and the veggie sandwich, or do you choose the applesauce and the hot soup? Do you touch your chair and then eat pizza with your hands, or do you push the chair with your foot and then still avoid eating any food that has been touched? Do you ride a crowded subway or drive your own car? Do you go to a movie theater or watch something at home?
Living your life as if you have crippling germaphobia is not healthy for you mentally (as the parent) and is also not doing your children any favours. There is plenty of evidence that having your kids grow up in very sterile environments will negatively impact their immune system as time goes on, both in terms of strength and allergies.
