The Centers for Disease Control and Prevention recommends that pregnant people get an RSV vaccine between 32 and 36 weeks of pregnancy during the period from September through January.<\/p>\n If you’re enjoying this article, consider supporting our award-winning journalism by subscribing.

Kennedy, Jr., a noted vaccine skeptic. It comes days after a panel of influential vaccine advisors, all of whom were handpicked by Kennedy, voted to rescind the recommendation for a universal birth dose of the hepatitis B vaccine, despite what experts decried as a lack of evidence.<\/p>\n According to Reuters, FDA officials started investigating the RSV therapies over the summer. Vaccine skeptics have claimed, without evidence, that the shots could increase the risk of seizures in some infants.<\/p>\n In 2023 the FDA approved Beyfortus, a type of antibody drug, for babies born during or entering their first RSV season and in children up to two years old who are vulnerable to severe RSV. The agency approved Enflonsia, a similar drug, in June 2025. As with all drugs approved by the FDA, these medications were extensively tested in clinical trials for safety and efficacy before they were given the green light.<\/p>\n If you enjoyed this article, I\u2019d like to ask for your support.
