NBC's "Today" show, after considerable backlash, deleted a tweet Thursday asking if vaccines are safe and linking to its segment with actress Jessica Biel.

The show said it removed the initial tweet because it "included an irresponsibly presented headline." Its new headline focused on doctors discussing "common vaccine myths."

The tweet in question had been screen-saved by Bloomberg's Ben Brody, with the reporter noting how the "ratio" on the "Today" tweet was "amazing."

A ratio on Twitter is a social media term that means the number of replies, invariably negative and critical, clearly outweigh the number of retweets of the content. In this case, the Biel tweet generated more than 1,200 replies and just six retweets.

Biel faced criticism across social media after she made an appearance at the California State Assembly alongside known anti-vaccine advocate Robert F. Kennedy Jr. to lobby against a vaccination bill.
