Extended Data Fig. 7. Population immunity over time from vaccination and infection by age group assuming immunity from infection wanes by 25% after 100 days.

Population immunity estimates among those aged 12–19 or aged 60 or above were less accurate as no subjects were between 12 and 17 years old, and few were above 65 years old. The lines indicate posterior medians and shaded bars indicate 95% credible intervals based on the fitted model.
