	Naïve for COVID-19 (Seronegative) (n=27)	Status after COVID-19 (Seropositive) (n=14)	p-value
SARS-CoV-2 MNT50 (day 0), IU/mL	<4•0 (0)	236.9 (102•3–548•7)	<0•0001
SARS-CoV-2 MNT50 (day 21), IU/mL	82•0 (62•4–107•2)	2003•1 (1023•2–3921•4)	<0•0001
SARS-CoV-2 MNT50 (day 49), IU/mL	632•5 (475•9–840•5)	3626•9 (2234•0–5888•4)	<0•0001

Data are geometric mean (95% CI). Statistical difference is calculated using a mixed effects linear regression model adjusted for sex with posthoc estimated marginal mean contrasts. MNT50=microneutralisation titre 50%. IU=international units.
