Covid-19, vaccines and its impact on pregnancy, fertility and breastfeeding

Updated: Feb 7

While Pregnant....

Vaccine induced antibodies transfers to our babies via breastmilk and placenta!

In a study of 131 women, 84 of them pregnant, it was found that the vaccine immune response was the same for pregnant or non-pregnant women. Side effects were not significantly different between the two groups. Antibodies were found in cord blood and breastmilk. (Hooray for the babies!)

Looks like the vaccine is looking like good news for us. Keep breastfeeding!

Last year, a Singaporean mother contracted the virus in her 36th week of pregnancy - all is well as she gave birth to a healthy baby with the covid-19 antibodies. Transmission of the virus in utero is very low. This has been more consistently backed by more studies. The placenta of covid positive pregnant mothers protects the baby. However, there have been reports of injury to the placenta which suggests extra care should be taken of these mothers.

Likelihood of covid while pregnant

According to the World Health Organisation, pregnant ladies are at higher risk of contracting the virus than non pregnant ladies. This is expected....given the suppressed immunity in order to hold a pregnancy.


No evidence of affected fertility by covid-19 vaccination

The british fertility society states that there is no reason not to vaccinate even if you are undergoing fertility treatments. It does not affect risk of miscarriages. (as of 11/02/2021)

A study by the Boston University School of Public health has found that the vaccine has no apparent impact on fertility in females or males who have received Pfizer-BioNTech, Moderna, or Johnson & Johnson vaccines. Covid infection may however temporarily reduce fertility in males - this can be avoided via vaccination. (January 2022)
