In their thoughtful, nuanced and interesting discussion, Jonathan Pugh, Julian Savulescu, Rebecca Brown and Dom Wilkinson argued that officials should recognise proof of prior infection as a valid exemption from vaccination requirements.1 This commentary agrees with parts of their analysis, but argues that the case for the exemption is less clear than the authors suggest, and the better approach is to allow officials flexibility: an exemption for natural immunity may be appropriate or may not.

In part, the disagreements may stem from different experiences in different societies. The authors are in the UK, and their experience may differ from the USA in multiple ways, three very glaring. First, the UK broadly used the AstraZeneca vaccine, which has higher risks than the mRNA vaccines, so our assessment of vaccine risks differs. Second, the UK has universal health insurance, so some of the access to testing issues that I raise concerns about may not apply there. And third, the risk of fraud or misrepresentation may be less in the UK—and other countries—than in the USA, where real concerns about, for example, fake vaccine cards have led to multiple arrests.2

Another issue is that information about COVID-19 changes fast—what was known when the authors wrote may no longer fit the current picture.
