Robert F. Kennedy Jr will require all new vaccines to undergo placebo testing, WaPo reports

U.S. Health and Human Services Secretary Robert F. Kennedy Jr intends to shift the way vaccines are tested, The Washington Post reported on Wednesday, citing a spokesperson from the HHS.

The potential change would require all new vaccines to undergo placebo testing - a procedure in which some people receive the vaccine and others receive an inert substance - before the results are compared, the paper said.
