Failure to receive the COVID-19 vaccine during pregnancy puts you and your baby at risk of serious COVID-19 complications, a new study found. Pregnant women who were not vaccinated had a four-fold higher infant mortality rate and were three times more likely to be sent to the intensive care unit than those who received the vaccine. Based on a study by Scottish researchers published in the medical journal Nature Medicine, the US health medicine webzine ‘Health Day’ reported on the 14th (local time).

Researchers led by Sarah Stock, a researcher at the University of Edinburgh’s Usher Institute in the UK, analyzed the medical records of more than 87,000 Scottish women who became pregnant between December 2020 and October 2021, when COVID-19 vaccinations began in the UK. There were significantly fewer pregnant women vaccinated during that time compared to other women. Only 32% of women who gave birth in the month of October 2021 were vaccinated, while 77% of women aged 18-44 who were not pregnant were vaccinated.

The researchers found that 77% of 5,000 pregnant women infected with COVID-19 had not been vaccinated. About 12% of infected pregnant women received a single dose of the vaccine, and only 11% completed the vaccine.

22.6 out of 1,000 babies born to unvaccinated women died. The general infant mortality rate is 5.6 per 1,000 live births, which is more than four times higher. The rate of premature babies was also 16.6%, which was more than double the rate of general premature babies (8%).

It cannot be concluded that the mother’s failure to receive the COVID-19 vaccine directly led to these infant deaths and premature delivery, the researchers said. However, it cannot be denied that the correlation between the two is quite high.

The researchers found that 98% of pregnant women admitted to the intensive care unit were not vaccinated. In addition, pregnant women who were infected with COVID-19 and developed symptoms were three times more likely to enter the intensive care unit and one to two times more likely to die.

“There was no signal that vaccination itself increased the risk of complications such as premature birth or infant death in the womb or during the neonatal period,” Stock said. way,” he said. He added that although the data was collected before the emergence of the omicron mutation, it is still recommended that pregnant women get vaccinated because it is a much safer route.

It is also worth noting that vaccination in this study did not increase the risk of adverse pregnancy side effects, such as future infertility, miscarriage, stillbirth, premature birth, birth defects, small babies and newborn deaths, said Timothy Rafael, PhD, Department of Maternal Medicine, North Shore University Hospital, USA. did.
