The Centers for Disease Control and Prevention (CDC and Prevention) urged pregnant women to get the Covid-19 vaccination Wednesday. Hospitals in high-risk areas across the US are seeing alarming numbers of mothers-to-be who have not been vaccinated.Women who are pregnant have a greater risk of developing severe illness or complications during pregnancy from the coronavirus. This could include miscarriages or stillbirths. According to CDC data, only 23% of them have received at least one dose.Dr Rochelle Walensky, CDC Director, stated that vaccines are safe, effective, and that it is urgent to increase vaccinations, as we face the highly transmissible Delta variant and severe outcomes from Covid-19 in unvaccinated pregnant women.After a CDC review of safety data from 2,500 women, the updated guidance was released. The analysis showed that there were no increased miscarriages in those who had received at least one dose (or more) of either the Moderna or Pfizer vaccines before 20 weeks. The miscarriage rate was around 13% according to the analysis. This is within the normal range.Recalls from top obstetrician organizations echo the CDC's advice. Although the agency has previously advised pregnant women to consider vaccination, it did not make a complete recommendation. This advice is also applicable to women who are pregnant or planning to become pregnant.Experts say that although pregnant women were not included on the studies that led to approval of Covid-19 vaccines but that real-world experience with tens to thousands of women has shown that they are safe and may provide some protection for newborns if given during pregnancy.This guidance is being issued amid an increase in COVID-19-related deaths, hospitalizations, and COVID-19 cases in the US. It was driven by the highly contagious Delta variant.Although the possibility of more severe illness in pregnancy than with earlier variants of the virus is being considered by some health officials, this issue is still under investigation.According to national statistics, the recent surge in pregnant women's cases is less than during the winter peak. However, in some states, where vaccination rates are low, the number of pregnant mothers-to-be is higher than during previous surges.This is the worst pandemic we have ever seen, according to Dr Jane Martin, an Ochsner Baptist Medical Center obstetrician in New Orleans. She said: It's demoralizing and exhausting. It seems like it doesn't have to feel like this.
