Well being and Human Companies Secretary Robert F. Kennedy Jr. would require new vaccines to bear placebo testing, marking what a division spokesperson known as “a radical departure from previous practices.”

Scientific trials take a look at whether or not the up to date vaccines generate an immune response that is similar to or higher than earlier variations of the vaccine.
