Out of an abundance of caution, Los Angeles County is following the recommendation of the Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) to pause the use of the Johnson & Johnson vaccine after reports that six women between the ages of 18 and 48 developed unusual types of blood clots 6 to 13 days after receiving the vaccine. This pause will last until the FDA and CDC complete their review, which is expected to take several days. Vaccine providers in Los Angeles County will contact patients about rescheduling or providing a new appointment for Pfizer or Moderna vaccine. These reactions are extremely rare, as nearly 7,000,000 people have received the Johnson & Johnson vaccine in the United States to date. People who received the vaccine in the last 3 weeks should look for any symptoms of these unusual clots, including severe headaches, abdominal or leg pain, and shortness of breath, and contact their medical provider if symptoms develop. People who don't have a medical provider can call 2-1-1 to connect with a healthcare provider.
