I did not read the article, but were the bad batches attributed to any factor like poor quality control in the manufacturing, etc.
CDC didn’t publish anything but the the VAERS database - still available, although many reported have been removed.
All data analysis was done by individuals downloading the relevant tables from the database, U.S. only data available.
FDA/Pfizer wanted a 75-year schedule for release of the data in the trials.
Some of the people working the database have non-medical manufacturing experience (20-45 years) and said there had to be systematic differences in the lots, rather than the injection method, because same lots show up different places. Per Pfizer/Moderna, all this is considered trade secrets, and will only be released if ordered by a court or FDA, after appeals.
A prior response noted that sources from the manufacturer data said four different dose sizes 3, 10, 30, and 100 nanograms. Plus (prior thread), if the injection hits a blood vessel, the injected material can go straight to a vein and then to the heart within a minute or two - which can result in myocarditis and other heart issues.
