疾控中心拒绝将MMR疫苗分开的呼声,理由是没有科学依据和疫苗接种率面临的风险。 CDC rejects call to split MMR vaccine, citing no scientific basis and risks to vaccination rates.

疾控中心代理主任Jim O'Neill呼吁将麻疹、流行性腮腺炎和风疹疫苗分开,这与前总统唐纳德·特朗普(Donald Trump)的无根据主张相呼应。 Acting CDC director Jim O'Neill has called for separate measles, mumps, and rubella vaccines, echoing former President Donald Trump’s unsupported claims. 疾控中心指出,没有科学证据表明,将MMR疫苗分开会提高安全性或有效性,专家们警告说,这可能会增加费用,需要更多探诊,并降低疫苗接种率。 The CDC states there is no scientific evidence that splitting the MMR vaccine improves safety or effectiveness, and experts warn it could increase costs, require more visits, and reduce vaccination rates. 美国制造商Merck和GSK认为,混合疫苗是安全、有效且对高覆盖率至关重要的。 Merck and GSK, the U.S. manufacturers, maintain that combination vaccines are safe, effective, and critical for high coverage. 推力来自将MMR与自闭症联系起来的不可信的主张,而自闭症已经完全被揭穿。 The push stems from discredited claims linking MMR to autism, which have been thoroughly debunked. 虽然疾病防治中心最近建议,由于小量的收缴风险,将微量甲状腺肿疫苗与幼儿的MMR疫苗分开,但这不适用于MMR疫苗本身。 While the CDC recently recommended separating the varicella vaccine from MMR for young children due to a small seizure risk, this does not apply to the MMR vaccine itself. 公共卫生官员强调,混合疫苗依然是保护儿童的标准。 Public health officials stress that combination vaccines remain the standard for protecting children.
