Dr. Molly O’Shea has noticed growing skepticism about vaccines at both of her Michigan pediatric offices and says this week’s unprecedented and confusing changes to federal vaccine guidance will only make things worse.One of her offices is in a Democratic area, where more of the parents she sees are opting for alternative schedules that spread out shots. The other is in a Republican area, where some parents have stopped immunizing their children altogether.She and other doctors fear the new recommendations and the terminology around them will stoke vaccine hesitancy even more, pose challenges for pediatricians and parents that make it harder for kids to get shots, and ultimately lead to more illness and death.AdvertisementAdvertisementAdvertisementAdvertisementThe biggest change was to stop blanket recommendations for protection against six diseases and recommend those vaccines only for at-risk children or through something called “shared clinical decision-making” with a health care provider.The phrase, experts say, is confusing and dangerous: “It sends a message to a parent that actually there’s only a rarefied group of people who really need the vaccine,” O’Shea said. “It’s creating an environment that puts a sense of uncertainty about the value and necessity or importance of the vaccines in that category.”Health Secretary Robert F. Kennedy Jr., who helped lead the anti-vaccine movement for years, said in announcing the changes that they better align the U.S. with peer nations “while strengthening transparency and informed consent.”But doctors say they are sowing doubt — the vaccines have been extensively studied and proven to be safe and effective at shielding kids from nasty diseases — at a time when childhood vaccination rates are already falling and some of those infectious diseases are spreading.AdvertisementAdvertisementAdvertisementAdvertisementOn Friday, the American Academy of Pediatrics and more than 200 medical, public health and patient advocacy groups sent a letter to Congress about the new childhood immunization schedule.“We urge you to investigate why the schedule was changed, why credible scientific evidence was ignored, and why the committee charged with advising the HHS Secretary on immunizations did not discuss the schedule changes as a part of their public meeting process,” they wrote.Many don’t know what ’shared decision-making’ meansO’Shea said she and other pediatricians discuss vaccines with parents at every visit where they are give …
