A study from the University of Oxford ensures that coronavirus vaccines prevent complications in pregnancy

It was performed in 41 hospitals in 18 countries. The impact of the Covid-19 Ómicron variant on maternal and neonatal outcomes was evaluated.

A study of the Oxford University carried out in 41 hospitals in 18 countries, revealed that Vaccines reduce complications in women and pregnant people against the Omicron coronavirus variantwhile unvaccinated have higher risks.

This is the “Intercovid 2022” study, published by the University of Oxford, in the scientific journal The Lancetwhich evaluated the impact of the Covid-19 Ómicron variant on maternal and neonatal outcomes.

the researchers studied 1,545 pregnant women diagnosed with Covid-19, and 3,073 pregnant women not diagnosed with the virus, in 41 hospitals in 18 countries.

The results showed that pregnant people, vaccinated and preferably given the additional booster dose, were “adequately protected” against the symptoms and serious complications of Covid-19 Omicron, and had “very low risk” of admission to care units. intensive.

The Omicron variant during pregnancy was associated with increased risk of maternal morbidity, serious pregnancy complications, and hospital and intensive care unit admissions, especially among symptomatic and unvaccinated women, and in particular, the risk of preeclampsia (high blood pressure). and signs of liver or kidney damage that can occur in women after the 20th week of pregnancy) were increased among women with severe symptoms.

Obese or overweight women with severe symptoms had the highest risk of maternal morbidity and serious complications.

The global network of hospitals coordinated by the Oxford Maternal and Perinatal Health Institute (OMPHI) conducted the study between November 27, 2021 and June 30, 2022, during which time Omicron was the predominant variant and the efficacy of Omicron was evaluated. efficacy of the vaccine against this variant.

For his part, the professor of Perinatal Medicine at the University of Oxford, José Villar, co-director of the Intercovid 2022 study, stated that they have “provided solid and evidence-based information on the increased risk of Covid-19 Ómicron during pregnancy of suffering severe maternal complications, especially among symptomatic and unvaccinated women.

“Our study clearly indicates the need for a complete vaccination schedule during pregnancy, and with a booster dose, to provide protection for at least 10 months after the last dose. Antenatal services around the world should strive to include vaccination against Covid-19 in the routine care of pregnant women,” she maintained.

The Buenos Aires Minister of Health, Nicolás Kreplak, shared the study published in The Lancet on his official Twitter account and remarked that “the province of Buenos Aires was one of the first to vaccinate this population.”

“Since the beginning of the pandemic, we have carried out active surveillance in pregnant people with a positive Covid. This strategy allowed us to detect that this population had greater complications against the non-pregnant positive ones,” he highlighted.

The provincial director of Gender Equity of the Ministry of Health of the Province of Buenos Aires, Sabrina Balaña, explained that this study “has a very important health value.”

“In addition to the evidence we had up to now, with strong results, it reinforces the importance of vaccinating women and pregnant people against the coronavirus, since it shows the increase in severe morbidity in unvaccinated women and the efficacy of the vaccine.” vaccination to protect against serious complications caused by Covid-19,” he explained.

And he remarked: “In this sense, it is important that we continue to protect pregnant people by completing the recommended doses and reinforcements.”
