<p>COVID-19 vaccination during pregnancy was not associated with preterm delivery or underweight newborns, in a study published by the U.S. Centers for Disease Control and Prevention (CDC) on Tuesday.</p><p>Rates of preterm birth were 4.9% among more than 10,000 women who received at least one dose of a COVID-19 vaccine, compared to 7.0% for roughly 36,000 unvaccinated women, researchers said on Tuesday in The CDC&#x27;s Morbidity and Mortality Weekly Report. </p><p> The difference was not deemed to be statistically significant.</p><p>In addition, COVID-19 vaccination did not increase the risk of delivering a baby who weighed less than usual for the number of weeks of pregnancy, the researchers found.</p><p>Results from the study support the CDC&#x27;s recommendation on the safety of COVID-19 vaccination during pregnancy.</p><p>&quot;Evidence of the benefits of COVID-19 vaccination during pregnancy continues to accrue, including the detection of antibodies in cord blood,&quot; the researchers wrote, noting that pregnant women with COVID-19 have increased risks for intensive care unit admission, need for mechanical ventilation and death.</p><p>The women in the study had become pregnant between May and October of 2020, before vaccines were available.</p><p>Nearly all who were vaccinated got the shots in their second or third trimester of pregnancy. Some 96% of them had received at least one dose of an mRNA vaccine from either Pfizer Inc and BioNTech or Moderna Inc . The remaining women received the single-shot vaccine from Johnson &amp; Johnson.</p><p>There was no difference in outcomes based on the timing of vaccination, or on which mRNA vaccine was received or how many doses.</p><figure class="op-interactive"><iframe height="315" src="https://www.youtube.com/embed/tByxqwg1IVw?enablejsapi=1" width="560"></iframe></figure><div class="iwantbar">Watch more in <a href="//www.iwantv.com.ph/">iWantv</a> or <a href="//tfc.tv/">TFC.tv</a></div><p>The data were drawn from eight healthcare organizations in six U.S. states, the report said.</p><p>The researchers noted that because they reviewed data collected for other purposes, they may have missed some vaccinations, and they lacked information on women&#x27;s previous history of birth-related complications. The study also lacked information on first-trimester vaccinations and on boosters, which were not available at the time.</p><figure class="op-interactive"><iframe height="315" src="https://www.youtube.com/embed/MVoehV83RkU?enablejsapi=1" width="560"></iframe></figure><div class="iwantbar">Watch more in <a href="//www.iwantv.com.ph/">iWantv</a> or <a href="//tfc.tv/">TFC.tv</a></div>
