Re: Are vaccine passports and covid passes a valid alternative to lockdown?
No need for this polarised debate, there is a middle ground.
The Head-to-Head article by Kirsty Innes, Daniel Sleat and Imogen Parker [1[ (Are vaccine passports and covid passes a valid alternative to lockdown? BMJ 2021; 375 doi: https://doi.org/10.1136/bmj.n2571 (Published 03 November 2021) serves to polarise the debate around vaccination status and entry to mass, live events, rather than solve it. When vaccine status is viewed as a barrier (or facilitator) to entry, then arguments, for and against, inevitably centre on the irreconcilable tensions between individual freedoms and public health. However, there is a middle ground where restrictions on individual freedoms do not necessarily need to be imposed for the sake of wider public health benefits - vaccination can remain a question of personal choice without fear of being denied entry to cultural or other events that constitute an important part of normal societal interactions.
A more helpful and non-polarising perspective is to view vaccine status as a data point rather than as a passport to routine social interaction. If vaccine status and other factors such as mask-wearing are used as data, the COVID transmission risk in almost any setting (planes, schools, theatres, restaurants, festivals etc) can be modelled based on the overall preponderance of susceptible and protected individuals at the event and the characteristics of the venue. When the risk modelling is combined with robust screening protocols such as at-home videoed testing prior to the event, and linked to ticketing data for the venue, public health officials can use evidenced based decision making to inform go/no-go decisions on the overall safety of the event on a case-by-case basis. This type of hyper-local, data-driven, real-time decision making can ensure that events that are important to the economy and mental health and wellbeing of individuals can go ahead in a way such that individual freedoms are maintained without jeopardising public health. Protocols have already been developed and trialled in live events since July 2021 , and modelling assumptions are available for wider scrutiny . It is time to stop viewing vaccination status in divisive, dichotomous terms, and pursue solutions that conciliate between the tensions of individual choice and public health. There are policy choices available that do exactly that.
