Specialists have been trying ahead to seeing outcomes from Johnson and Johnson’s COVID-19 vaccine trials for months. The vaccine is a logistical dream in comparison with the opposite two approved within the US. It’s a lot simpler to retailer, and it requires just one shot as a substitute of the 2 required by its opponents. The one excellent query was how properly it really labored. On Friday, they obtained their reply — it really works fairly properly.
In a 43,783 individual trial that spanned the globe, the vaccine was 66 percent effective at stopping average to extreme COVID-19. Now, 66 % would possibly appear to be a let down in comparison with the 90-plus % efficacy from Pfizer/BioNTech and Moderna. However that’s a matter of perspective. Earlier than outcomes of these vaccine trials got here out, researchers had been hoping for efficacies of between 60 and 70 percent. (By comparability, seasonal flu vaccines are given the thumbs up when they’re 40-60 percent effective.)
All that’s to say, the brand new vaccine candidate continues to be excellent at what it does, as many people have pointed out. That’s as a result of 66 % effectiveness is healthier than zero, which is the place a whole lot of us are working proper now.

Think about being shielded from dying 28 days after a single shot, and shielded from extreme illness after 49 days – in opposition to all variants. https://t.co/gGCcDbMglr pic.twitter.com/gPCDgG8oNJ

Not solely that, however the vaccine was 85 % efficient at stopping probably the most extreme types of the illness. That’s fairly implausible.
Right here’s the not-so-fantastic factor. The explanation that the vaccine was ‘solely’ 66 % efficient within the trial is that it didn’t do as properly in South Africa, the place a worrying new variant is circulating extensively. Whereas the efficacy within the US was 72 %, the efficacy in South Africa was 57 %.
That’s nonetheless not unhealthy. But it surely does imply that there’s a clock ticking within the background as the corporate strikes to get the vaccine candidate approved. The variants are spreading shortly — one was first detected in the US this week. The earlier the world might be vaccinated, the higher the possibility all these vaccines might be at stopping the unfold of the virus.
“We’ve obtained to get the primary dose to as many individuals as doable,” virologist Akiko Iwasaki advised STAT. “These variants which might be extra transmissible and doubtlessly much more deadly are on the rise. I believe time is basically what we’re preventing in opposition to.”
