Vaccinated pregnant women pass on antibodies to babies
However, initial analyzes are promising. Accordingly, corona vaccinations could apparently not only reliably protect the mother. The antibodies formed after the vaccination are also transferred to the unborn child in the womb. Antibodies can also be detected in breast milk, doctors report in the American Journal of Obstetrics and Gynecology. The study is considered to be the most extensive on the subject to date.
In addition, vaccination during pregnancy resulted in higher antibody levels than a natural infection. This suggests that the vaccination could even provide more reliable protection. However, the scientists cannot yet say with certainty whether the antibody levels detected in the umbilical cord and breast milk are sufficient to ensure that the baby is also immune from Covid-19.
Why pregnant women are not vaccinated yet
“The excellent vaccine efficacy is very encouraging to pregnant and breastfeeding women who were not included in the initial vaccine studies,” said Andrea Edlow of Massachusetts General Hospital.
The Standing Vaccination Commission (Stiko) has only recommended vaccinations to pregnant women if they have a special, increased risk of a severe course of Covid-19. In order to protect pregnant women at least indirectly, their close contact persons have moved up in the vaccination sequence. Every pregnant woman in Germany can now name up to two people who then belong to group two for prioritization. However, these are far from being their turn in all federal states.
- According to an overview study, pregnant women are at risk for Covid-19. For the analysis, researchers evaluated 77 studies and thus the data from more than 11,400 women. The likelihood of being pregnant Had to go to intensive care with Covid-19 was 62 percent higher than for non-pregnant women in the same age group. The The probability of ventilation was even 88 percent higher. An investigation by the US Disease Control Agency (CDC) came to a similar conclusion.
Women who got Covid-19 while pregnant also had one higher risk of premature birth. In the UK, 12 percent of pregnant women with Covid-19 gave birth before 37 weeks of pregnancy. Normally this is only the case with 7.5 percent of pregnant women. In the United States, the proportion of premature births to mothers who had become infected was 15.7 percent. In the rest of the population it is only ten percent. Most children are born in the last trimester of pregnancy when there is a good chance they will develop healthily. One reason for the accumulation of premature births can also be that the children are brought into the world early by the doctors in order to be able to better treat the mothers after the birth.
That too Risk of thrombosis and preeclampsia, also known as pregnancy poisoning, increases when pregnant women are diagnosed with Covid-19.
In most cases However, pregnant women do not pass the virus on to their children. In a study of 62 pregnant women who tested positive, the virus could not be detected in the blood of the umbilical cord. Also, none of the later born babies tested positive.
There are repeated reports of stillbirths after the mothers became infected with the coronavirus. Recently there have been two such cases in Israel. It is unclear whether the infection was actually the cause. According to a recent study from Canada, for which data from more than 430,000 pregnant women were evaluated, stillbirths occurred more frequentlyif the mother was infected with the coronavirus. However, there are Cases very rare. In another study, children of Covid 19 patients were mostly born healthy and developed within the next six to eight weeks just like children of mothers who had not tested positive.
In very In rare cases, inflammation associated with Covid-19 can apparently damage the placenta in a manner similar to that of lung tissue. This emerges from previously unpublished study data for which more than 1,700 pregnant women were examined. In three cases, children of affected mothers with brain damage were born, said David Baud from the University of Lausanne in Switzerland, who is working on the study, “Nature”.
The fact that pregnant women have to be treated more frequently with infections in the hospital is also due to the fact that doctors are particularly careful with them. This effect is not only evident in diseases.
“Pregnant women should avoid getting infected”
However, caution alone cannot explain the frequent hospital admissions of pregnant women with Covid-19. Pregnant women are also more susceptible to other infectious diseases. There are several explanations for this: Pregnancy is also a challenge for the lungs because the mother and fetus have to be supplied with oxygen at the same time. At the same time, the growing belly presses against the diaphragm, one reason why many pregnant women are short of breath. In addition, the immune system of pregnant women does not work at full strength – so that it does not accidentally attack the unborn child.
The tricky thing about Covid-19: Some patients do not notice how bad they are actually doing. Despite threateningly low oxygen levels, they have no shortness of breath – that is why they are also referred to as “happy hypoxics”. The low supply of oxygen can be a problem for unborn babies.

Pregnant women are also at risk because they are not allowed to receive all medication. Normally, people with severe Covid 19 would also turn on their stomach for better ventilation. This is not possible with pregnant women. “Pregnant women should avoid getting infected,” said Jeffrey Goldstein of Northwestern University in Chicago months ago. Panic, says the pathologist, is not appropriate. But be careful.
