nyt None of these changes are evidence-based. All of them run counter to what the C.D.C.’s own experts (and most of the nation’s leading medical groups) have advised. And all are likely to sow confusion, undermine public trust and ultimately drive the nation’s vaccination rates down. “We are already hearing about pregnant women who test positive for Hep B deciding not to get the shot,” said Dr. Paul Offit, director of the Vaccine Education Center at the Children’s Hospital of Philadelphia. “Because the message they’re getting from that recommendation is that the vaccine itself is dangerous.”Proponents of the push to align U.S. recommendations with those of so-called peer nations such as Denmark, Japan and Germany — all of which recommend fewer shots than the United States — have billed it as a common-sense corrective. But, as innumerable doctors and scientists have explained, when it comes to public health, countries with fewer shots on their must-have list are not actually our peers.In Denmark, to take the administration’s favorite example, prenatal care is free and universal. More than 95 percent of pregnant women are screened for hepatitis B, and those who test positive are promptly treated and duly monitored. In Japan and in most European nations, primary care systems have the capacity to find and vaccinate children who face a higher risk for vaccine-preventable diseases — and in many of those countries, paid sick leave also helps minimize the spread of contagions through schools and offices.None of this is true in the United States. cr：杭之冯玥感谢您关注此人
