COVID-19 Vaccine Effectiveness During Pregnancy
In an earlier study , the scientists found that though pregnant and lactating people made fewer protective antibodies after the first vaccine dose than a control group, the difference disappeared after the second dose. A new study shows that even after two or three doses, p regnant people are nearly twice as likely to get covid-19 as those who are not pregnant . The analysis, based on Epic medical records of nearly 14 million U.S. patients since coronavirus immunization became available (Jan.2021- Jan.0222), found that pregnant people who are vaccinated have the greatest risk of developing covid among a dozen medical states, including being an organ transplant recipient and having cancer. 110,000 pregnant persons included in the study were 90% more likely to have been infected with coronavirus than the same number of people who were not pregnant. The next-highest risk was among organ transplant recipients (80%). Patients with compromised immune systems, had 60% greater odds of c
