president Trump’s proposal last week Childhood vaccines, including measles, epidemic and rubella, or MMR, should be separated.
Dr. William Moss, executive director of the international vaccine access center at Johns Hopkins Bloomberg School of Public Health Health School, is shocked.
MOSS mentioned a former doctor in 1988 that he did not listen to that recommendation since “Andrew Wakefield”. Withdrawal with fraud.
According to the survey, Wakefield did not obtain financial benefits against two lawsuits for vaccine manufacturers and two lawsuits against a single measurement vaccine patent. The license to practice medicine has been canceled.
President Trump’s remarks were also derived from Wakefield. In a video posted on social media, he said, “I adopted one recommendation in 1998,” when the president first asked to divide the MMR vaccine into an individual component.
“This is a return to unbelief strategy.” Wakefield had a financial stake in undermining MMR, and science never supported his claim. “
MMR vaccine division risk
Dr. Howard Markel, a pediatric epidemic expert and medical historian, said the stake in dividing the union vaccine is not abstract.
“The immune schedule is very carefully resolved, so the vaccine is the most frequent at an age,” he explained. “When you start sharing things, you create a barrier. My parents always come back, choose, choose, and cover the coverage. That’s simple.”
Dr. Peter Hotez, a pediatric epidemic specialist and vaccine expert at Baylor College of Medicine, argued that the request for vaccine split vaccines is part of a wide range of campaigns to distrust vaccinations.
“There is a new Zinger every few weeks Tee Merotalthen intervalthen aluminumHe is now sharing MMR. ”
The medical risk of the MMR constant dismantling is clear. Measles are one of them Most infectious viruses When circulating, every time the vaccination speed falls, it can cause the occurrence. During pregnancy, rubella infections can cause congenital rubella syndrome, leaving a baby with a deaf, blindness or heart defects. Fashionable subdivision, which is dismissed too often, can cause infertility of youth men.
Programming results are the same. Moss pointed out that parents are already complaining about too many injections. Dividing the MMR into a separate shot increases the number of visitors and the number of needles faced by children, while weakening the protection of rubella and fashionability.
Markel creates barriers, especially for families with limited resources.
Dr. Walt Orenstein, former head of CDC’s vaccination program, described the union vaccine as the basis of modern prevention.
“A union vaccine was developed to reduce missing opportunities, increase the scope of application, and minimize the trauma of multiple injections,” he said. “If you cancel the progress, your children will be in danger.”
Measles -only vaccines do not exist in the United States. You cannot enter a pediatrician office or retail pharmacy and ask for a standalone shot.
In order to make it possible to use measles in the United States, manufacturers must wait for measles to occur to test vaccines in a new clinical trial. Then you need to submit data for FDA approval and to build a production and distribution system from the beginning. There is no market for solo measles vaccines, so companies should be sure that there is sustainable demand. Experts say that given the firm use of MMR, experts say it is unlikely to say.
Recycling
The objection to the combined vaccine is not new, the UC Berkeley Medical Historian Elena Conis pointed out.
“The resistance to the vaccine and the concern about the form and content of the vaccine are as old as vaccines,” she said. “Concerns about the combined vaccine are as old as the combined vaccine itself.”
She pointed out that even before Wakefield, her parents could not obtain a separate vaccine in the 1970s, and why they were asking why they reflect the debate over DPT (Diphtheria, Tetanus and Pertusis) vaccines.
The new momentum that separates measles from rubella is driven by repeated myths. The rubella vaccine “contains fetal parts”. Indeed, the rubella virus was originally grown up in a human fetal cell lord developed in the 1960s, which has been replicated since then without further abortion.
During production, the virus is purified and destroyed, biologically inactivated, and leaves only trace DNA or protein fragments at a much lower level than the natural background of food or human body. Regulatory agencies, such as the Food and Drug Administration, confirm that this level is safe. Advocates to separate MMR often collide this history with the wrong claim that the vaccine contains fetal tissues. Separated rubella is presented as moral correction even if the actual barrier is introduced and the protection of pregnant women and babies weakens.
Conis also stressed that resistance often depends on how people recognize the seriousness of each disease.
Conis pointed out that the public did not always see various infections as equal. Sometimes rubella has been feared more than measles or pandemic.
In particular, MUMPS said, “The MMR vaccine was often treated as humor rather than fear until researchers began to emphasize complications such as infertility and hearing loss.”
Japan provides a attention example. In the early 1990s, Japan withdrew the MMR vaccine combined with concerns about the safety of the popularity of vaccines and returned to measles. The results were less likely to be protected because of the lower absorption of rubella and epidemic vaccines compared to measles.
Decades later, Japan faced repetitive rubella in 2013 and 2018-2019, leading to a case of congenital rubella syndrome. Due to the initial policy of vaccinating girls about rubella, large -scale cohorts of adult men are forced to be expensive due to poor immunity and leave Japan vulnerable to infectious diseases.
Dr. Paul Offit, a pediatrician and vaccine expert at the Philadelphia Children’s Hospital, warned that if he split the MMR vaccine, he would repeat the past mistakes.
“We have come before. Andrew Wakefield promoted a single antigen vaccine, and in the UK, we almost derailed measles. Science was not fraud, but the damage was practical. Thousands were not protected.
James Colgrove, a historian of Columbia University, said that there is a deep root in this kind of backlash.
“The original anti -vaccination movement in the 19th century was actually a movement for national coercion,” he said. “It was always a paradox of forced vaccination. It is very effective, but it is also one of the most likely to cause backlash.”
Conis has argued for wider autonomy and orders.
“There was always vaccination between individual choices and public health,” she said. “Parents must give up autonomy to promise better health for the population. It is acceptable to some people. Personal freedom is more important for others. Today we have a liberal approach to the highest level of government.”
Colgrove added that policymakers faced delicate balance. “Non -medical exemptions are important for making laws more politically and actually spreading backlash,” he said. “At the same time, if the exemption is greater, the more people can opt out, the more risk of damaging immunity.
And in the case of offit, the bigger risk is the pattern of the wrong information itself.
“These arguments are not new and recycled,” he said. “If suspicion is rooted, it is very difficult to restore public trust.”
According to studies in several countries, complex vaccines improve intake and timely by reducing the combined promises and the number of injections required. Children who receive a combination formulation are more likely to complete the entire schedule on time, and low -income parents are less likely to fall behind when multiple protections are delivered in one shot.
In the case of Dr. Demetre Daskalakis, former director of the recent disease control and prevention center, this proposal reflects politics rather than science.
“This is not about safety. It’s about ideology,” he said. “We’ve already seen an instruction to back up data.”
Dr. Debra Houry, who recently resigned as the chief science and medical manager of CDC, reflects concerns.
“The story of separating MMR into individual components did not come from scientists,” she said. “It was led by political personnel without public health expertise.”
According to MOSS: “I don’t need it, no solo vaccine can be used in the United States. There is no reason to follow that path.”
