Johnson & Johnson (Janssen)

Authorized for individuals ages 18 years and older.
Type: Viral vector
Dose: 1 dose
How well the vaccine works: The Johnson & Johnson (Janssen) vaccine was 66.3% effective in clinical trials at preventing laboratory-confirmed COVID-19 illness in people who had no evidence of prior infection two weeks after receiving the vaccine. People had the most protection two weeks after getting vaccinated.
Safety: There is an increased risk for getting thrombosis with thrombocytopenia syndrome (TTS), following Johnson & Johnson COVID-19 vaccination. TTS is a serious, but rare, adverse event that causes blood clots with low platelets. Women ages 18-49 years, especially, should be aware of the rare but increased risk of this adverse event. Tragically, 9 of the 54 people with TTS died. TTS death rates are highest among women 30–39 years of age (1.93 death per million doses) and 40–49 years of age (1.8 deaths per million doses). There are other COVID-19 vaccine options available for which this risk has not been seen. CDC recommends people receive an mRNA COVID-19 vaccine (like Pfizer or Moderna) over Johnson & Johnson’s COVID-19 vaccine. Learn more about the Johnson & Johnson COVID-19 vaccine and TTS.
