FDA Restricts Johnson & Johnson's COVID-19 Vaccine Amid Blood Clot Concerns

Strategic Insights

— 2 min read

US health authorities, including the Centers for Disease Control and Prevention (CDC), recommended Pfizer's and Moderna's two-course vaccination program over Johnson & Johnson's (J&J) single vaccine due to similar health concerns. Despite this, the FDA determined that the benefits of the J&J COVID-19 vaccine currently outweigh the risks for adults. The agency has restricted the vaccine to only adults and requires a booster shot for those who received a single dose. Reports of Thrombosis Thrombocytopenia Syndrome (TTS) blood clots have emerged, causing the FDA and CDC to pause and later lift the administration of the vaccine.

Key Takeaways:

  • The FDA restricted the J&J COVID-19 vaccine to only adults due to the risk of life-threatening blood clots within two weeks of vaccination.
  • The Centers for Disease Control and Prevention, along with other US health authorities, recommended Pfizer's and Moderna's two-course vaccination program over J&J's single vaccine due to similar health concerns.
  • The FDA has estimated the reporting rate of TTS deaths at 0.48 per million doses of vaccine.
  • There are 60 confirmed cases of TTS from the J&J vaccine and nine deaths reported.
  • The factors that put an individual at risk for TTS following administration of the Janssen COVID-19 Vaccine remain unknown.
  • The CDC recommends that anyone who received a single dose of the J&J vaccine get a Moderna or Pfizer booster shot.
  • Dr. Peter Marks, FDA director of the Center for Biologics Evaluation and Research, emphasized that the J&J COVID-19 Vaccine still has a role in the current pandemic response in the United States and across the global community.

Statistics:

  • 17 million people in the US received J&J's COVID-19 vaccine as of April 1, according to Today.
  • The CDC recorded 15 cases of TTS out of eight million doses.
  • There are 60 confirmed cases of TTS from the J&J vaccine and nine deaths reported.
  • The FDA estimates the reporting rate of TTS at 3.23 per million doses of vaccine.
  • The reporting rate of TTS deaths is 0.48 per million doses of vaccine.
