Important vaccine update from Keck Medicine of USC

Dear Valued Patient,

This morning, federal health officials recommended a pause in the use of the Johnson & Johnson vaccine due to six reported cases of a rare and severe type of blood clot in individuals receiving the vaccine.

The Food and Drug Administration and Centers for Disease Control and Prevention are making the recommendation out of an abundance of caution. This adverse reaction appears to be extremely rare; more than 6.8 million doses of the Johnson & Johnson vaccine have been administered in the U.S.

All six cases occurred among women between the ages of 18 and 48, and symptoms occurred six to 13 days after vaccination.

How this news might affect your vaccine appointment

We will not be administering any Johnson & Johnson vaccines through Keck Medicine of USC. If you have an appointment for this vaccine, you will be rescheduled to a Pfizer vaccine.

Federal health officials are recommending that people who have received the Johnson & Johnson vaccine who develop a severe headache, abdominal pain, leg pain or shortness of breath within three weeks after vaccination contact their primary health care provider.

Vaccine appointments for the Pfizer and Moderna vaccines will continue as planned. Please show up for your appointment as scheduled.

You can also book Pfizer or Moderna vaccine appointments through https://myturn.ca.gov/ or accessing our self-scheduling portal directly by visiting https://www.keckmedicine.org/coronavirus-vaccine/self-scheduling/.  These vaccines are safe and highly effective in preventing severe COVID-19 disease, hospitalization and death.  

Our vaccine supply should not be affected by this pause.

Keeping you informed

We will continue to monitor the situation and keep you updated on the status of the Johnson & Johnson vaccine. You can also check our COVID-19 vaccine web page for updates.

Thank you for being our patient and trusting Keck Medicine with your care.
