I understand, I would like to have this too. But this particular vaccine has not been around long enough (or been tested in animals for an extended trial) to have such studies, I believe. Would you trust a direct link to VAERS-the Vaccine Adverse Events Reporting System? VAERS would actually be a primary source, whereas a journal study would be a tertiary source. I first searched for all recorded adverse events, 175,000 events came up. Then I narrowed the search to death and disability, and 26,000 events came up.
