The proportion of women giving birth between January and October without adverse outcomes
having received one or more doses in pregnancy (91.9% 95%CI 91.6 to 92.1) is similar to the
proportion in women who did not receive any doses in pregnancy (91.6% 95%CI 91.5 to 91.6)
(Figure 4). These positive outcomes were similar across all age groups in vaccinated and
unvaccinated women (Figure 5). For the more recent period (women vaccinated from 16 April
and delivering from 17 April 2021), when all pregnant women were routinely offered vaccination
on the basis of age, women who had received at least one dose of COVID-19 vaccine during
their pregnancy were more likely to give birth without any of the reported adverse outcomes
than women who had not been vaccinated in pregnancy (92.9% 95%CI 92.7 to 93.1 compared
with 91.6% 95%CI 91.5 to 91.7) (Figure 6).This difference was more apparent in those aged 30
years and older (Figure 7).
The stillbirth rate for women who gave birth having received one or more doses in pregnancy
(3.60 per 1,000, 95%CI 3.14 to 4.13) was similar to the rate for those who had not received any
doses in pregnancy (3.90 per 1,000, 95%CI 3.71 to 4.10) giving birth between January and
October 2021 (Figure 8). In the same period, the proportion of women who had received one or
more doses in pregnancy giving birth to babies with low birthweight (5.01%, 95%CI 4.84 to
5.19) was comparable to those who had not received any doses in pregnancy (5.33%, 95%CI
5.26 to 5.40) (Figure 6). Similarly, 0.87% (95%CI 0.79 to 0.95) of women who had received one
or more doses in pregnancy and 0.77% (95%CI 0.74 to 0.80) of those who had not, gave birth
to a very low birthweight baby (Figure 9).
The proportion of women who received one or more doses in pregnancy having premature
births was 5.97% (95%CI 5.78 to 6.17), compared with 5.88% (95%CI 5.81 to 5.96) in those
who had not (Figure 10). The proportion of women with very premature births was 1.47%
(95%CI 1.37 to 1.57) in those who received one or more dose in pregnancy and 1.72% (95%CI
1.68 to 1.77) in those who had not. The proportion of women with extremely premature births
was 0.89% (95%CI 0.82 to 0.97) in those who received one or more dose in pregnancy and
1.21% (95%CI 1.18 to 1.25) in those who had not.
