Osei's Framework and the Vaccination Requirement
Philosopher Mara Osei argues: 'In a pandemic, restrictions on movement are justified only when three conditions hold: the restriction is necessary to prevent significant harm, it is proportionate to that harm, and less restrictive alternatives have been shown to fail. Necessity alone is insufficient; a measure that works but imposes excessive burdens fails the proportionality test. Moreover, the burden of proof lies with those imposing the restriction, not with those subject to it.' A local board cites Osei's framework to decide whether to require proof of COVID-19 vaccination for indoor dining. The board has data showing that unvaccinated patrons are more likely to be hospitalized, but also that ventilation improvements reduced transmission in restaurants by 60%. The board has not tried a policy of rapid testing at the door. A restaurant owner argues that vaccination requirements are 'the only way' to keep businesses open safely.
1. Apply Osei's three conditions to the proposed vaccination requirement for indoor dining. What is the strongest argument for and against it under her framework?

For: the requirement is necessary to prevent significant harm (unvaccinated patrons are more likely to be hospitalized), and it may be proportionate if the burden is modest. Against: the third condition-less restrictive alternatives have been shown to fail-is not met. The board has not tried rapid testing at the door, and ventilation improvements already reduced transmission by 60%. Under Osei's framework, the burden of proof lies with the board. Because a less restrictive alternative has not been shown to fail, the vaccination requirement is not yet justified. The strongest argument for it would need evidence that testing or ventilation alone is insufficient.
2. What evidence would the board need to gather before its policy could satisfy Osei's framework?

The board would need evidence that rapid testing at the door has been tried and failed to reduce transmission or hospitalizations to an acceptable level. It would also need to show that the vaccination requirement's burden is proportionate-for example, that it does not unduly exclude people who cannot be vaccinated or that alternatives like takeout are available. Finally, it should document that the requirement is necessary, meaning the harm from unvaccinated dining is significant and not adequately addressed by ventilation. Without these data, the board is imposing a restriction before proving that less restrictive alternatives fail, which Osei's framework forbids.
3. How would Osei likely respond to the restaurant owner's claim that vaccination requirements are 'the only way' to keep businesses open safely?
Read the worked answer
Osei would likely reject the claim as premature. Her framework requires that less restrictive alternatives be 'shown to fail,' not merely asserted to be inadequate. The board has ventilation data showing a 60% reduction and has not tried rapid testing. The owner's 'only way' claim is an empirical assertion that lacks supporting evidence. Osei might also note that the burden of proof rests with those imposing the restriction, so the owner cannot shift that burden by declaring alternatives impossible. She would demand a comparison of outcomes before accepting the superlative.
