Shares of Tylenol maker Kenvue bounced back sharply before the opening bell a day after President Donald Trump promoted unproven and in some cases discredited ties between Tylenol, vaccines and autism. “Don’t take Tylenol,” Trump instructed pregnant women around a dozen times during the White House news conference Monday, also urging mothers not to give their infants the drug, known by the generic name acetaminophen in the U.S. or paracetamol in most other countries. Aside from Tylenol, the consumer health company makes Band-Aids, Listerine and other household brand names. The analyst anticipates a positive reaction for Kenvue’s stock at the opening bell on Tuesday given the lack of new scientific evidence. Shares of Kenvue Inc., based in Summit, New Jersey, climbed nearly 5% in premarket trading.
