There were medical breakthroughs in treating other conditions and diseases. The cicadas emerged from underground, and Perseverance landed on Mars.
“Oh, this is huge. And you know, I take it back. Maybe these two stories together [COVID-19 vaccines and the malaria vaccine] are the biggest stories of the decade, possibly century. It's astonishing. People have been trying for decades to figure out how to create a vaccine for malaria. It is so much harder than creating a vaccine for a bacterial disease or for a virus because the malaria parasite is a whole organism.
“This year, we have some of the first results showing that the technique can be used safely and apparently effectively to treat sickle cell disease. It's been used in another blood disease called beta thalassemia and then a really nasty disease called. It's a fatal condition, and there was a trial using CRISPR-Cas9 to protect people from this basically a misfolded protein that causes terrible disease and death. They’re all still in the early stages.
