6 questions pregnant women or those planning a pregnancy commonly have about the risk of Covid-19 vaccination

Women who are pregnant during Covid-19 may have doubts as to how to behave to ensure that they and their baby are safe, and what effect vaccination might have. Here are the answers:

1. Is it ok for a pregnant woman to get vaccinated against Covid-19?

Yes, pregnant women can be safely vaccinated against Covid-19. The US Center for Disease Control and Prevention (CDC) encourages women who are pregnant or planning to become pregnant to get vaccinated to reduce the likelihood of contracting Covid-19 and minimize the risk of severe illness if they do. A report of pregnant women who received Moderna, Pfizer-BioNTech or Johnson & Johnson vaccines found no reports of unborn babies being negatively affected by their mother’s vaccination.

2. Can a baby be affected by the mother's use of alcohol gel or spray?

Alcohol gel or spray has no effect on the baby as it is a medical component that can be used safely. For the most effective disinfection, we should use standardized alcohol gel or spray with at least 70% alcohol content. Food-grade alcohol is another option for mothers, as it is safe and has no residue. It can be purchased from drugstores but if you buy it online, choose a brand that is licensed by the Food and Drug Administration, Ministry of Public Health.

3. Does pregnancy weaken the immune system?

Yes, pregnancy usually somewhat weakens the overall immune system. However, there is insufficient evidence to say that pregnancy makes it easier to catch Covid-19 but pregnant women should get vaccinated against Covid-19 as well as being vaccinated against tetanus and influenza and anything else advised by their antenatal doctor.

4. What are the symptoms if a pregnant woman is infected with Covid-19?

According to a study, pregnant women have similar symptoms to other people such as sore throat, fever, fatigue, loss of smell and taste and others. However, they are more likely to develop severe symptoms that could lead to preterm birth or require termination of pregnancy. If infected with Covid-19 during pregnancy, please consult a doctor immediately.

5. Can Covid-19 be passed on to babies?

The report also found that babies have a 3-5% chance of infection and in most cases they will be asymptomatic. Therefore, for their baby’s safety, mothers should take care of their health and wash their hands or use alcohol spray frequently.

6. If a mother has been infected with Covid-19, should she breastfeed?

Infected mothers can breastfeed their babies. However, they should wear a mask and wash their hands thoroughly with soap before holding their baby and avoid coughing or sneezing while feeding. Alternatively, mothers can pump and have an uninfected person feed their baby their milk from a bottle. Don’t forget to carefully clean the breast pump after every use.

Besides having an appointment to see a doctor for a pregnancy check-up and getting Covid-19 vaccinated, it's important for the good health of each baby that each mother stays healthy, keeps clean, washes their hands with soap or alcohol gel, avoids meeting people unnecessarily, and keeps a clear mind.
