  But when Johnson & Johnson filed for an emergency use authorization from the Food and Drug Administration for its Covid-19 vaccine in early February, it reported that its overall efficacy in preventing Covid-19 cases that produced symptoms was 66.1 percent. The Moderna vaccine and the Pfizer/BioNTech vaccines reported efficacy levels around 95 percent.
  That gap in efficacy numbers is fueling some people’s perception that the Johnson & Johnson Covid-19 vaccine isn’t as good. However, scientists say that these numbers can’t be fairly compared to one another. The efficacy levels of the Covid-19 vaccines are specific to the clinical trials that produced them, and those trials were not conducted in the same ways.

  Testing in the real world means dealing with all the confounding factors of the real world. Depending on which volunteers are selected and where they are, they face different infection rates of the virus. They have varying access to health care. Some places had stricter lockdowns than others, or started them at varying times, so participants experienced different public health measures. Michigan issued a mask mandate in March 2020 while California issued one in June 2020, for example.
  Timing is critical too. The Moderna and Pfizer/BioNTech studies finished enrolling participants in their phase 3 trials in October and reported their results in late November. The Johnson & Johnson phase 3 trial only finished enrolling participants in December 2020 and reported their results in January.
