Kennedy Jr. intends to shift the way vaccines are tested, a move that the agency said will increase transparency but that medical experts fear could limit access to vaccines and undermine the public’s trust in immunization depending on its implementation.
The potential change outlined in a statement says all new vaccines will be required to undergo placebo testing, a procedure in which some people receive the vaccine and others receive an inert substance — such as a saline shot — before the results are compared.
Vaccines for new pathogens are often tested this way. But for well-researched diseases, such as measles and polio, public health experts say it makes little sense to do that and can be unethical, because the placebo group would not receive a known effective intervention.
Medical and public health experts also expressed dismay that the testing change could require coronavirus vaccines, and potentially others, to undergo costly and, in their view, unnecessary studies that would probably limit vaccine production and access — and leave more Americans at risk of preventable disease.
