People have fears. Rational or not, they are fears. Internet amplifies those fears, creates echo chambers. One of the worst thing that happened to humans were smartphones for the masses, which came with 24/7 social media connections. Unfortunately, facts and logic does not work to change people's minds. They tend to do the opposite - people dig their heels in even more, reinforcing their original fears. Perhaps one way to alleviate those fears would be, rather than give them numbers, have society cover said risks. If only extremely few people have severe negative reactions, offer them free lifetime healthcare. The cost to society should be minimal (cost of lifetime healthcare * the odds of negative reaction * population to be vaccinated). Maybe for those vaccinating kids, provide them with a period of time after vaccination with priority care, should the kid have a negative reaction (so they don't have to spend 12hrs in an ER to see a doctor, or wait a month for a clinic appointment - a reality for many US residents, even those with good health plans). For those who are afraid of deaths due to vaccinations, offer ludicrous compensations - if the chances of death are in fact zero, offer $100M or more per death, if you never have to pay it but people will feel reassured, it's a win-win. We managed to get some people to get COVID19 vaccines with a prize lottery, reassuring them that in exchange for them taking a risk for society, the society will cover those risk for them might be worth a try, it would seem fair, and it doesn't have to violate people's free will by forcing them to get vaccinated. Perhaps such vaccination assurances is the legislation that is needed.
