ACIP Votes to Lift Pause on J&J COVID-19 Vaccine
The CDC's Advisory Committee on Immunization Practices voted to uphold the original language of the emergency use authorization for Johnson & Johnson's COVID-19 vaccination, and is possible the 1-dose vaccine could resume Saturday.

Members weighed the implications a continued pause would have in the United States and the world against the benefits of having a single-dose, easy to store vaccine readily available. Ten members voted to lift the pause, while 4 were opposed and 1 abstained. Deliberations focused on whether to include warnings of the potential for rare blood clots within the updated recommendation.
New fact sheets about the risk of blood clots associated with the vaccine will be distributed to patients when they make an appointment to get vaccinated; the sheets will list symptoms including headache, shortness of breath, chest pain, leg swelling, and persistent abdominal pain, among others.
During a press conference later Friday, Peter Marks, MD, PhD, director of the FDA’s Center for Biologics Evaluation and Research, said it is possible that J&J vaccinations could restart as early as Saturday.
One of the factors that went into the pause, said Acting FDA Commissioner Janet Woodcock, was that health officials did not know how many of the people who had just recently received the vaccination would develop the rare clots. In addition, it was unknown how many providers would know how to recognize the symptoms and treat appropriately, without heparin.
Health officials also stressed that the fact sheets for patients would be written in lay language, and CDC Director Rochelle Walensky, MD, said they are conducting outreach with the American College of Obstetricians and Gynecologists.
Outreach to those most at risk was on the minds of the panel earlier.
Although she voted yes, “I am concerned that the consumers and women in this age group in particular, will not be adequately informed just by the FDA,” said Beth Bell, MD, MPH, a clinical professor at the University of Washington and member of ACIP. In her comments, Bell stressed that public health agencies and partner organizations should make sure that people are informed and receive a balanced perspective.
The decision comes after the European Medicines Association (EMA) recommended resuming use of the J&J vaccine
Out of around 8 million doses of the J&J vaccine administered to Americans thus far, 12 cases of cerebral venous sinus thrombosis (CVST) in combination with thrombocytopenia have been confirmed, mostly among younger women, within about 2 weeks of receiving the shot.
“I have no problem with the continued availability of this vaccine,” said Pablo J Sánchez, MD, a professor of pediatrics at Ohio State University and ACIP member who voted against the motion. “But I think that if we just make a blanket recommendation knowing the risks that seem to have biologic possibility and severity, I think we have to have stronger language and make sure people are informed appropriately.”

Of patients with confirmed reports of TTS following the J&J vaccine, 2 used oral contraceptives, 7 had obesity, 2 had hypothyroidism and 2 had hypertension. No patients reported diabetes or coagulation disorders.
Initial symptoms included headache after 6 or more days following vaccination, chills, fever, nausea/vomiting, lethargy and abdominal pain, while later symptoms included severe neck pain, unilateral weakness, speech difficulty, and seizure, among others.

“In terms of Johnson & Johnson and the Baltimore facility…this is a process between the FDA and the companies, and we expect J&J to work through this with the FDA,”
“Our vaccination program was never built on one vaccine. We have plenty of vaccine supply of Pfizer and Moderna. There are tens of millions of doses already out in the country—of Moderna and Pfizer—ready to be administered.”
