- A new study on the coronavirus in Singapore indicates that babies whose mothers are infected during pregnancy are likely to be born with COVID-19 antibodies.
- Neutralizing antibodies could provide immunity from birth, although researchers cannot say what kind of protection babies receive or how long it will last.
- Of the 16 pregnant women in the studies, five gave birth at the time of publication and all newborns had detectable levels of antibodies in their blood. Two women lost their babies and one of the possible abortions could have been caused by complications of COVID-19.
Neutralizing antibodies are the proteins that the immune system creates to stop the spread of a virus. Antibodies bind to the ear protein, preventing it from infecting cells. Coronavirus vaccines will teach the immune system to respond to infection by inducing specific antibodies to COVID-19. Antibodies may disappear after a while, but COVID-19 protection may last longer than that thanks to another set of immune system components: blood-patrolling B and T cells that will preserve the memory of the virus. .
Researchers have no idea how long the immunity to the coronavirus will last, if protection occurs after infection or exposure to the virus. It is hoped that immunity can last at least a year, but it will take longer for researchers to make those determinations. However, a subset of the population could have immunity to COVID-19 from the time they were born: babies whose mothers survived the coronavirus during pregnancy.

A few days ago, a Singapore report said a baby was born with antibodies that can neutralize the new coronavirus. Essentially, the newborn has immunity to COVID-19 from the uterus. Her mother contracted the disease before the pandemic and before her pregnancy. She was only 10 weeks pregnant when she became infected and gave birth to a healthy baby in mid-November. The mother no longer has antibodies against the coronavirus, but her son does.
At the time, it was unclear whether all mothers infected with the pathogen during pregnancy would give birth to children with detectable coronavirus antibodies. The news comes from the same country, as researchers report a growing number of babies with antibodies. Reuters reports that a new study says five women were born to women with COVID-19 infection and that they all have antibodies.
The study examined 16 women and found that most of them experienced a mild case of COVID-19. Older women and people with a higher body mass index experienced a more severe version of the disease.
Five of them had given birth when the study was published and all mothers had antibodies.
The researchers also measured antibody levels in children and found that babies with mothers who had the disease closest to the disease had higher amounts of antibodies.
The research found that none of the women transmitted the virus to babies. None of the pregnant women died, but two of them lost their babies. Only one of the two prenatal deaths could be related to complications of COVID-19.
The study could be limited, but the Singapore Obstetrics and Gynecology Research Network said in a statement that “the results of the study were reassuring.”
“This shows that the incidence and severity of COVID-19 among pregnant women is parallel to the general population trends,” the group said.
That said, researchers still warn that it is unclear what kind of protection the antibodies will provide to babies and more data is needed. Infants and children usually experience milder cases of COVID-19, but there have been exceptions. Researchers will monitor babies to see if antibodies decrease in time. A different one Reuters The report on the issue points to research from China claiming that antibodies decreased in babies born to COVID-19 survivors.
