Highly Anticipated CDC Vote on J&J Vaccine Likely Today April 23, 2021 -- Although there is no way to know how the vote will go when the CDC's Advisory Committee on Immunization Practices meets later today on the recommended pause in use of the Johnson & Johnson vaccine, many experts predict the panel to suggest the J&J vaccine rollout start back up.. Few additional cases of the rare, but serious blood clots that prompted the pause have emerged, which could increase the likelihood that vaccinations restart as early as this weekend. The CDC and FDA initially recommended pausing the rollout on April 13 based on reports of six cases of rare blood clots. The 21 members of ACIP held a hastily called meeting the next day to evaluate the evidence. They decided that they needed more time to make a recommendation.
