Johnson & Johnson (NYSE:JNJ) announced that its single-shot Covid-19 vaccine was 66% effective in preventing moderate and severe cases of Covid-19 in its global phase 3 trials. Efficacy varied by region, with the shot proving 72% effective in the U.S., 66% effective in Latin America, and around 57% effective in South Africa. Although the headline efficacy figures put J&J behind both Moderna and Pfizer, which have vaccines that are over 90% effective in the market, J&J’s shot remains very promising for a couple of reasons. Firstly, the shot only requires a single dose and this should greatly reduce logistical costs and help to vaccinate populations twice as fast with a given number of doses compared to the other shots on the market. This is valuable in the midst of a pandemic. Secondly, the shot has shown complete protection against hospitalization and deaths, 28 days post-vaccination.
