(CNN) Centers for Disease Control and Prevention vaccine advisers voted Sunday to recommend the Johnson & Johnson Covid-19 vaccine for the US, and CDC Director Dr. Rochelle Walensky almost immediately signed off on the recommendation. The US Food and Drug Administration authorized the J&J vaccine on Saturday. More research is needed to now for sure, but the FDA analysis also hinted that the J&J vaccine may help prevent asymptomatic infections. "The Johnson & Johnson vaccine was tested against the South Africa variant in South Africa, tested against the variant in Brazil. "When you look at what we really compare about which is preventing hospitalizations and deaths, the Johnson & Johnson vaccine comes in at 100% once it's had a chance to work."
