Huh? What vaccine...? there is no vaccine for SARS/SARS2 or MERS for that matter... Where are you getting your information? Most of the trials were stopped at the preclinical stage. There is ZERO data out there on any deaths related to non-clinical trials of a SARS or MERS vaccine... But keep on spreading the bullshit... or post some links to your sources - would love to read those papers.
