Prioritizing the vulnerable over the susceptible for COVID-19 vaccination

Abstract

The COVID-19 pandemic led to a health crisis with widespread social and economic adverse effects. To address the fallout, vaccine development has been pursued in record time. Several vaccines have already been deployed in countries worldwide, but as the supply is limited, these have been provided selectively. Various allocation schemes, premised on ensuring an equitable distribution, have prioritized the elderly, given their apparent susceptibility. For the Philippines and possibly other countries with extremely limited supplies, the elderly need not always be given primary preference. The level of available supplies can be so low that the immediate focus of allocation should be on mitigating both infection and transmission. The proposed alternative vaccine allocation framework gives priority to groups rendered more vulnerable, such as those who are unable to avoid prolonged exposure to possibly infected people because of medical necessity or occupational conditions. Vulnerable groups include healthcare and other essential workers as well as patients requiring continued healthcare services. The proposed allocation scheme is meant to be complementary to concurrent public health measures, which have to be maintained though made less restrictive as the pandemic is brought under control.
