Johnson & Johnson's COVID-19 Vaccine: How Does It Work?

  • Operation Warp Speed, launched in early 2020, helped speed up the pace of vaccine innovation, turning the normally 10+ year clinical trials process into one that takes less than a year. To learn more about the vaccine development process, check out this post by Nidhi.

    Although vaccine development has been significantly accelerated, it is essential to understand that vaccine development has not been rushed. In fact, despite operating in a public health emergency (the COVID-19 pandemic), vaccine research has been thriving. This is thanks to scientific collaboration, funding, and a quick and thorough review process, allowing scientists across the globe to develop the COVID-19 vaccines in under a year. 

    In this article, we will discuss Johnson & Johnson's COVID-19 vaccine. The Johnson & Johnson (J&J) vaccine will likely be approved by the US Food and Drug Administration (FDA) for use by late February or early March. The J&J vaccine is different from other COVID-19 vaccines in that it only requires one dose. As such, it may be the saving grace to the seemingly slow and clunky vaccination rollout in various countries, including the United States.

    Why might the J&J vaccine be the pandemic saving grace?

    The J&J vaccine may be the next one to receive approval -- i.e., after the Moderna vaccine and the Pfizer vaccine. There are various advantages and disadvantages to using this vaccine.

    The biggest drawback of the J&J vaccine is that it has lower efficacy than the Moderna and Pfizer vaccines.
