“ J&J is a very good vaccine. I also believe it's probably a two-shot vaccine," said Dr. Ashish Jha, dean of the Brown University School of Public Health. "It's really urgent that people get that second shot pretty quickly. "Probably one is not enough. And everybody who has had one needs a second one two months after the first. They are going to get full protection if they do that," he said.” Probably probably, fuck any doctor who says probably.
