2) Besides 100 mil for the US, the J&J vaccine has been ordered by UK 🇬🇧 (30mil), EU (200 mil), Canada 🇨🇦 (38 mil) and 500 mil by COVAX nations.
3) While overall efficacy was 66% (pretty good), excluding South Africa and Brazil where variants dominate, US trial efficacy was 72%. Severe illness efficacy was 85%, and efficacy against mortality was 100% so far during followup. This is key. bbc.co.uk/news/world-us-…
4) here is where all the vaccines are made in the US. J&J produced on the East Coast, Michigan; and Indiana.
5) And remember, while the J&J uses a custom common cold adenovirus, it is engineered that the adenovirus cannot replicate, while the DNA it carries - encoding the spike protein of the #SARSCoV2 - can be copied into mRNA, and then into the spike. But adenovirus itself is sterile.
