Cumulative incidence curves of the documented infection outcome in pregnant women, CHS, 20 December 2020 through to 3 June 2021. The main line is the point estimate of the cumulative incidence and the shaded areas are the 95% CIs. The vertical lines at days 28 and 77 demarcate the period when an individual was considered ‘fully vaccinated’ in the manuscript (7 through to 56 d after receipt of the second dose). The curve represents the numbers at risk at each time point, along with the cumulative number of events. Each individual was included only once in each study group but individuals could move from the unvaccinated to the vaccinated group after receipt of the vaccine.
