Those who are not allergic to the vaccine and are able to take the vaccines should be required to take them, especially kids who are attending any form of in person school. However vaccines that have not been around for at least 5 years should not be required because long term effects aren't known and that might be a concern for many people. But between that time period people should hold themselves accountable for the decisions they make that may or may not result in them becoming sick, and or spreading the virus.
