COVID Shots Cut Pregnancy Danger
20 Feb
Summary
- COVID vaccination linked to lower preeclampsia risk in pregnant women.
- Booster doses showed a significant reduction in preeclampsia odds.
- Study involved over 6,500 pregnant women across 18 countries.
A significant international study involving over 6,500 pregnant women across 18 countries indicates that COVID-19 vaccination may offer protection against preeclampsia. Published on February 18, 2026, the findings suggest that vaccination, particularly a booster dose, is linked to a lower risk of this severe pregnancy complication characterized by dangerously high blood pressure.
The research, conducted between 2020 and 2022, found that contracting COVID-19 during pregnancy increased preeclampsia risk by 45%. However, for vaccinated individuals, especially those who received a booster, the risk was significantly mitigated. Women receiving a booster dose showed 33% lower odds of developing preeclampsia. For those with pre-existing conditions like diabetes or chronic hypertension, a booster was linked to a 58% reduced risk.
Researchers theorize that the vaccine may enhance the immune system's ability to manage inflammation, thereby supporting placental and blood vessel health. The study, which also noted lower rates of preterm births and delivery complications among vaccinated women, supports the importance of equitable vaccine access for pregnant individuals globally, including booster shots.
