At CHI Memorial, safety is our highest priority, and we only administer vaccines that are recommended by the FDA as safe and effective. The FDA continues to recommend all three vaccines - Pfizer, Moderna and Janssen/Johnson & Johnson - as safe and effective. The CDC and FDA paused use of the Janssen/Johnson & Johnson vaccine for a short period of time to study a small number of reports about the development of rare blood clots. Following this pause, the FDA and CDC both determined blood clots forming after Janssen/Johnson & Johnson vaccination is extremely rare and the vaccine remains safe and effective. People at risk for developing blood clots should talk with their doctor before COVID-19 vaccination.
