Are some COVID-19 vaccines more effective than others? It’s hard to tell since they weren’t directly compared in studies. But experts say the vaccines are alike on what matters most: preventing hospitalizations and deaths. “Luckily, all these vaccines look like they’re protecting us from severe disease,” said Dr.
Monica Gandhi of the University of California, San Francisco, citing study results for five vaccines used around the world and a sixth that’s still in review.
And real-world evidence as millions of people receive the vaccines show they're all working very well. Still, people might wonder if one is better than another since studies conducted before the vaccines were rolled out found varying levels of effectiveness.
