As much as mandatory processes could suck, the downside of letting people do whatever crazy thing they want is dead kids. Disneyland and other venues and organizations with high-density occupancy (sadly) should require visitors to present valid proof of current vaccinations prior to admittance. Yuppie flus aren’t real, and society shouldn’t pander to snowflake nonsense; the only exemptions should be for legitimate, independently-reviewed medical situations. People can bandy about “democracy” and “freedom,” which they mean anarchy that impacts others with their externalities.
