Life expectancy before vaccines was 47 years. A lot of those short lives were children, like yours. People probably ate healthier, there were all kinds of home remedies, and we had prayer, but vaccines are mostly what drove life expectancy up to 79 years. Diptheria, Pertussis, Tetanus, Measles, and Polio have all killed people, especially little people. Vaccines have all but eliminated the threat. Not vitamins and not prayer.
God gave our scientists the gifts and talents to create relatively safe and effective vaccines, and that was a blessing. People who subvert this blessing of God for their own political agenda are resisting the Grace of God. Jesus healed people through miracles, but Jesus doesn't live with you in your home, nor does he show up at the town square to heal your children before they spread the measles to all of their playmates in school or the church nursery. Yes, God can heal your kids, but God can also protect your kids from the side-effects of vaccines. Just ask.
Some parents who refuse vaccines aren't religious at all. They're just the typical conspiracy theorists who believe they've figured out the big lies of the deep state. This deep state wants to control us, and vaccines would be part of that government interference in our lives. Like taxes and video surveillance. To these folks, I would suggest: Get over yourself. The government isn't surveiling you unless you've made specific threats, and it's not embedding trackers in your vaccines. Aliens aren't looking to abduct you. Most people and government organizations don't really care about you at all. And the deep state doesn't really exist, at least not beyond the typical Elons who use money to attain more power. But again, it's not really about you. Governments, even oppressive ones, are created for the greater good of the governed. And, yes, the greatest good of those in charge. But vaccines are for the greater good of those governed. Some people experience adverse effects from vaccines, but many more avoid death because of them. I tend to favor avoiding death.
Please, crazy moms, get your brats vaccinated so that you aren't responsible for killing them. That's much worse than yelling at them about using wire hangers.
