COVID-19 Vaccines: 1 Safety Surveillance 2 Manual
While there is no indication that pregnant women have an increased susceptibility to infection with SARS-CoV-2, there is evidence that pregnancy may increase the risk of severe illness and mortality from COVID-19 disease in comparison with non-pregn...ant women of reproductive age. As seen with non-pregnant women, a high proportion of pregnant women have asymptomatic SARS-CoV-2 infection and severe disease is associated with recognized medical (e.g., high body-mass index (BMI), diabetes, pre-existing pulmonary or cardiac conditions) and social (e.g., social deprivation, ethnicity) risk factors. Pregnant women with symptomatic COVID-19 appear to have an increased risk of intensive care unit admission, mechanical ventilation and death in comparison with non-pregnant women of reproductive age, although the absolute risks remain low. COVID-19 may increase the risk of preterm birth, compared with pregnant women without COVID-19, although the evidence is inconclusive.

The immunization program has been going well until a rumor begins that one child in a community far from the capital has become sick after receiving a vaccine. The rumor is becoming stronger every day and is picking up coverage on local radio.
Concerned that the rumor might make caregivers concer...ned about bringing their children for vaccination, a few frontline workers (FLWs) go to the house of the children who fell sick. They find out from the child's mother that she never thought her son was sick due to the vaccination he received. The mother agrees to speak to other caregivers during a community gathering to explain that her son's illness was not caused by his vaccination. She also responds to a few questions to reassure other caregivers about the safety and advantages of immunization.
