Is there a mathematically optimal means for distribution? (eg, 2 persons in every household or somehow best spreading out to achieve the benefits of herd immunity). I'm not in the most vulnerable group, so I'm okay with waiting. But I wonder if targeting 'likely vectors' would be most effective. Administer in airports for anyone incoming?
