J&J VACCINE PAUSE: Federal regulators are recommending that states hold off on administering the Johnson & Johnson vaccine, while health experts look at six reported cases of people who had severe blood clots after getting the vaccine. Thatâs out of more than 6.8 million people who got the vaccine.
