Their immunity is more lasting than that of newborns with antibodies acquired during pregnancy – they are lost for a period of between 3 months and a half years, according to a study by medics from Tokuda Hospital
The immunity of babies who have had COVID-19 is longer than that of babies who have acquired antibodies from their mothers during pregnancy.
This shows a study by a team of medics from Tokuda Hospital led by Dr. Radka Maslarska, head of the neonatology department there. It covers more than 25 children born in the hospital from last September to June this year, and monitors their immunity between 3 and 6 months after birth. Two groups were studied – those born with antibodies acquired by their mothers who became ill during pregnancy, and those who became ill shortly after birth. The results will be presented at the upcoming Neonatology Congress in October.
“The conclusion is that the survivors have longer-lasting immunity and protection, while newborns who are born with antibodies by the sixth month in more than 90% no longer report such,” Dr. Maslarska told 24 Chassa.
In only 2 to 4%
of the cases
the coronavirus
can pass
through the placenta
and infect
the baby
while it is still in the mother’s womb. But with regard to antibodies, fortunately, the opposite is true – those that the mother produces when she spends the disease, in most cases pass into the baby’s blood.
“In over 95% of those over 25 children we included in the study, antibodies were found for a history of COVID infection, ie. they had passed antibodies, “explained the neonatologist. The children covered by the study were born between 3 and 6 months after the mother’s illness.
Despite the low probability of this happening, the hospital also has
child born with
COVID virus
Along with him, the study included another newborn who fell ill 20 days after birth.
“Those who had antibodies as a result of their mothers’ illness between 3 and 6 months in more than 90% of cases no longer had antibodies to protect them from COVID. Children who have been infected and become ill have antibodies after 6 months. This gives reason to believe that the survivors have good immunity against the virus, including in very young children and newborns, whose immunity is not perfect, “explained Dr. Maslarska.
Frequent admission of babies and young children with COVID has been reported in Tokuda in the last month and a half. Now
predominate
those of age
from 20 days to 5-6
years until
before August
the flow of children
patients was in
teenage
age
The change is due to the delta variant, which largely affects young unvaccinated and non-vaccinated, including the parents themselves.
“It simply came to our notice then. There are more young children, infants up to 1 year and newborns, as many of their parents have not been ill and vaccinated. Many young people are now becoming infected, and these parents pass it on to their children. Our youngest patients are usually from 20 days of age onwards, when they have already had a little more contact, this contributes to infection, “said Dr. Maslarska.
She expects the cases to jump with the departure of the children to school and kindergarten.
In the current wave, children are getting sicker. Newborns, for example
often lift
temperature and
they maintain it for some time, which is not typical for them in principle. Among other typical symptoms for adults – loss of appetite, vomiting, diarrhea, now children have more frequent pneumonia, which was not typical in previous waves, the doctor said.
