(CNN) — Vaccine advisers to the US Centers for Disease Control and Prevention on Wednesday put off making any decision about the recommendations for Johnson & Johnson’s coronavirus vaccine, saying they need more information about a rare type of blood clot.

Members of the Advisory Committee on Immunization Practices committee said they did not have enough information to make changes in their recommendations, or even to suggest extending a pause in administering the vaccine.
