Protection against increased risk of pregnancy complications is offered by the COVID-19 Omicron booster vaccine, according to a new study from Oxford University in the UK and Hadassah University Medical Center in Jerusalem.

The Israeli principal investigator, Dr. Michal Lifshitz, is a US nursing researcher. Obstetrics and Gynecology At the medical school in Hadassah – said “Israel is a pioneer in advocating for pregnant women to be vaccinated against the pandemic and has one of the highest percentages of women who have received the third vaccination in the world. We are witnessing the lowest rate of seriously ill pregnant women in Israel in the world. “Findings from an international collaboration led by the University of Oxford’s Oxford Maternal and Perinatal Health Institute (OMPHI), along with researchers from Hadassah and other leading international centers, have sparked significant interest in a leading journal, The Lancet. announced. It has just been published under the title “Pregnancy Outcomes and Vaccine Efficacy During Omicron as a Variant of Concern, INTERCOVID-2022: A Multinational Observational Study”.Researchers from 41 medical centers in 18 countries investigated maternal and neonatal Omicran COVID-19 by studying 1,545 pregnant women diagnosed with the variant and 3,073 pregnant women not diagnosed with infection as controls. We evaluated the variants.The study was conducted between November 27, 2021 and June 30, 2022. At this time, Omicron was the most common strain. Vaccine efficacy against variants was also evaluated. pregnant It is associated with an increased risk of maternal illness, severe pregnancy complications, and hospitalization, especially among symptomatic and unvaccinated women.

It also increases the risk of pre-eclampsia. This is a serious condition that usually occurs in the second trimester (after 20 weeks) and causes high blood pressure, protein in the urine, swelling, headaches and blurred vision.

A woman should be encouraged to be fully vaccinated, preferably with a booster dose, to prevent severe her COVID-19 symptoms and complications.

Prevention of serious symptoms

In this study, mRNA vaccines were most effective in preventing severe COVID-19 symptoms and complications, but viral vector vaccines were also most effective in preventing severe COVID-19 symptoms and complications, but viral vector vaccines were also effective at least 10 days after the last dose for both types of vaccines. It provided adequate protection for a month.

José Villar, Professor of Perinatal Medicine at the University of Oxford, Co-Director of INTERCOVID, said: 2022.“Of concern, 4% to 7% of unvaccinated women diagnosed with a COVID-19 Omicron variant during pregnancy developed severe symptoms of the disease.” He said. “This study underscores the need for a full vaccination course, preferably booster, during pregnancy to provide protection for at least 10 months after the last dose. should strive to include vaccination against COVID-19 in routine care. pregnant womanProfessor Aris Papageorghiou, Oxford Professor of Fetal Medicine, who co-led INTERCOVID 2022, concluded: due to serious illness. Universal full vaccination is needed because it is impossible to predict who will develop severe symptoms and complications. Full vaccination coverage against is still inadequate. ”
