Worth noting that while the article states it has an efficacy of 62.1%, it does provide 100% protection against severe symptoms/hospitalization/death: https://www.astrazeneca.com/media-centre...rials.html
Well, no, it doesn't say that it provides 100% protection. It simply says that there were none in their trial, they don't claim that this will be the normal case. The control group had 15 hospitalizations, it's not enough to claim that the vaccine will prevent all those. EDIT: The same is actually true for the BioNTech, Moderna and J&J vaccines: in the phase 3 trials, none had a death in the group that received the vaccine. But it still doesn't guarantee 100% protection against death.
Still, the data is encouraging, and it seems that this time they avoided the chaos of their first trial and ran things properly.
