That's the responsibility of the FDA, EMA etc., to make sure all of the above is met. However to be open to vaccine injury claims, in the current societal climate (lots of malicious actos and antivaccine disinformation among the public), would risk the financial viability of vaccine makers. That's a longtime problem in the US (hence some of the vaccine makers are protected by the National Childhood Vaccine Injury Act) and other countries.
