Newborn baby with coronavirus immunity – BGR

• A baby has been born with COVID-19 antibodies that may offer protection against infection with the novel coronavirus.
• The baby’s mother survived a mild case of COVID-19 in March, when she was 10 weeks pregnant.
• The mother’s antibodies to SARS-CoV-2 were gone, but doctors found the boy was born with circulating antibodies.

According to recent estimates, the new coronavirus is at least a year old, and that only counts the time it has infected humans. It is not known how old the virus might be and how long it evolved in animals before jumping to humans. We still don’t know which animals allowed him to mutate so that he could infect human cells, but it is hoped that this question will be answered.

Even though it has already been around for a year, the virus continues to surprise the scientific community. Researchers continue to discover new ways the virus affects the human body, including unexpected symptoms such as painless and bleeding teeth that fall out. The latest surprise comes from Singapore. A mother who survived the illness in March in the first trimester of her pregnancy gave birth to a healthy, COVID-free baby boy six months later. But this newborn baby has something that other babies born to infected mothers don’t: antibodies to the coronavirus that could give him immunity to COVID-19.

Doctors have studied pregnancy in relation to COVID-19 from the first few months of the pandemic, finding that mothers are unlikely to pass the disease to their babies. But mothers have also never been observed transmitting COVID-19 antibodies to their babies.

Céline Ng-Chan, 31, took a trip to Europe in March with her parents, her daughter and her husband. Only the females in the group were infected with the SARS-CoV-2 virus. Ng-Chan’s mother, Choy Wai Chee, had a severe case and spent 29 days on a survival machine. Celine and her 2-year-old daughter Aldrina were mildly ill and discharged from hospital after 2.5 weeks, according to Straits Times.

At the time of her diagnosis, Ng-Chan was 10 weeks pregnant. She developed antibodies, but they were tested for until the end of her pregnancy. She gave birth to her son Aldrin on November 7, a healthy 3.5kg boy without COVID.

But doctors found the child had circulating antibodies to the virus.

“It’s very interesting. His pediatrician said my Covid-19 antibodies were gone, but Aldrin had Covid-19 antibodies.” The mother said Straits Times. “My doctor suspects that I transferred my Covid-19 antibodies to him during my pregnancy.”

Aldrin may not necessarily be the first newborn to inherit antibodies from his mother. A 29-year-old woman tested positive during her 36th week of pregnancy in March. Her baby was born in the same hospital and it was also found to have circulating COVID-19 antibodies.

A hospital spokesperson said babies born to coronavirus survivors are being comprehensively assessed by a team of doctors. Maternal and umbilical cord blood is processed using PCR testing, and so far all mother-newborn pairs have tested negative. It is not known how many women have given birth after being infected during pregnancy.

The most interesting question about Aldrin’s immunity concerns B and T cells. As recent studies have shown, immunity to COVID-19 is quite promising in people who survive the disease. Regardless of the lifespan of the antibodies, white B and T cells appear to have a much longer lifespan and they may offer even better protection than expected against reinfection. Scientists have conservative expectations for coronavirus immunity in general, expecting it to last up to a year, just like other immunities to other human coronaviruses.
