More misleading information? Yes we know the delta variant is more contagious vaccine or no. Question is how is it compared to adenovirus vaccines.
From the same article:
Separately, preliminary findings of a Scottish study published in The Lancet last month found that the Pfizer vaccine provided 79% protection against all infections from the Delta variant, compared with 92% against the Alpha variant. The same study, which analyzed data from 5.4 million people in Scotland found the the Oxford-AstraZeneca vaccine offered 60% protection against infection with the Delta variant compared with 73% for the Alpha variant.
I don’t think that’s a huge difference but if given the choice, an mRNA makes more sense. Over 3x more people with the AZ vaccine got infected with the Alpha variant vs the PFizer. 27% vs 8%
