As if navigating a pandemic isn’t daunting enough, the added layer of pregnancy can amplify the anxiety surrounding COVID-19. Expectant parents find themselves grappling not just with the risk of contracting the virus but also with the implications for their developing child. While research continues to emerge about the effects of COVID-19 on pregnant individuals and their babies, many questions remain. With the introduction of several COVID vaccines, concerns about their safety for pregnant or breastfeeding individuals have also surfaced.
Pregnant individuals are at greater risk for certain infections due to changes in their immune systems and bodily functions, and there’s a potential risk of transmitting infections to their babies. This raises a critical question: Can a baby be born with COVID-19, or can an expectant parent pass antibodies that provide some protection?
Research Indicates Pregnant Women Can Transfer COVID Antibodies to Their Babies
Recent studies suggest that expectant mothers can indeed pass COVID antibodies to their babies while in utero. This is significant because a newborn’s immune system typically doesn’t start functioning until they are about 2 to 3 months old, relying on antibodies received from the mother through the placenta or breastfeeding.
In a January 2021 study, it was found that 67% of newborns born to mothers with COVID-19 antibodies also had these antibodies in their systems. This study aimed to assess whether COVID-19 infection led to complications during childbirth—findings indicated it did not—while also examining the prevalence of COVID-19 antibodies among pregnant women and their partners.
Another investigation involving 1,470 women from April to August 2020 at a hospital in Pennsylvania revealed that 72 out of 83 pregnant women who tested positive for COVID-19 antibodies successfully transmitted them across the blood-placental barrier. According to one of the study’s senior researchers, Dr. Alex Johnson, it appeared that earlier infection in pregnancy resulted in a greater transfer of antibodies to the baby.
Dr. Johnson, a microbiology professor at a prominent medical school, mentioned in a recent interview that these findings could influence recommendations for when to vaccinate pregnant individuals against COVID-19. While the data suggests that vaccinations early in pregnancy may offer enhanced protection for newborns, he cautioned that thorough studies on vaccination safety for expectant mothers are still necessary.
Understanding the Implications of COVID Antibodies in Newborns
So, what does it mean for babies born to mothers with COVID-19 antibodies? Antibodies are proteins produced by the immune system in response to pathogens. When the body encounters a virus, white blood cells generate specific antibodies to combat it.
In the case of COVID-19, antibody production may take between one to three weeks post-exposure, and not everyone produces them. Tests for COVID antibodies typically check for the presence of two types of immunoglobulins, IgG and IgM. Interpreting these results can depend on various factors, including whether the individual is showing symptoms and the levels of these antibodies.
Why is this important? The studies indicated that the antibodies that crossed the placenta were primarily IgG antibodies, the most prevalent antibody found in human blood. These antibodies can provide the infant with temporary immunity until their own immune system is active. It is hoped that the IgG antibodies related to COVID-19 will similarly protect newborns.
Importantly, none of the infants in these studies showed the presence of IgM antibodies, which typically appear first during an infection. This absence suggests that the babies were not infected with COVID-19.
The Implications for COVID Protection in Infants
Ultimately, these findings could assist healthcare providers in enhancing infant health. Maternal vaccinations have proven effective in preventing newborn deaths from various diseases, and if mothers can transmit COVID-19 antibodies, it may influence vaccination recommendations. This could potentially grant infants some level of immunity shortly after birth, although the extent and duration of that protection remain uncertain.
Just as the Tdap vaccine has been administered to pregnant individuals since 2012 to protect newborns, scientists are hopeful that incorporating the COVID vaccine during pregnancy could similarly shield infants from the virus.
What We Know About the COVID-19 Vaccines and Newborn Protection
Currently, while research shows that IgG antibodies can cross the placenta, questions linger about how effectively these antibodies protect against COVID-19, how long that protection lasts, and whether these infants may still contract COVID-19 later on. Further investigation is needed to determine the optimal timing for vaccinating pregnant individuals to maximize antibody transfer to newborns while also assessing how timing affects the duration of IgG antibodies in the babies.
The Centers for Disease Control and Prevention (CDC) has indicated that individuals who are pregnant and contract COVID-19 face an increased risk of severe illness and complications, emphasizing the importance of protecting both their lives and those of their newborns.

Summary:
Recent studies indicate that expectant mothers can transfer COVID-19 antibodies to their babies, offering potential protection during the early months of life. The research suggests that timing of infection during pregnancy may influence the amount of antibodies passed to the infant. However, further studies are needed to determine the effectiveness and duration of this protection, as well as the best timing for vaccinations in pregnant individuals. The CDC emphasizes the importance of safeguarding both expectant parents and their newborns from severe COVID-19 outcomes.
