Yes, all of the COVID-19 vaccines are very good. No, they’re not all the same.
Public-health officials are enthusiastic about the new, single-shot COVID-19 vaccine from Johnson & Johnson, despite its having a somewhat lower efficacy at preventing symptomatic illness than other available options. Although clinical-trial data peg that rate at 72 percent in the United States, compared with 94 and 95 percent for the Moderna and Pfizer-BioNTech vaccines, many experts say we shouldn’t fixate on those numbers. Much more germane, they say, is the fact that the Johnson & Johnson shot, like the other two, is essentially perfect when it comes to preventing the gravest outcomes. “I’m super-pumped about this,” Virginia’s vaccine coordinator told The New York Times last weekend. “A hundred percent efficacy against deaths and hospitalizations? That’s all I need to hear.”
