Flublok: what safety margin did regulators accept?

influenza vaccine, recombinant hemagglutinin · Influenza HA
Check my plan vs. these
Safety margin at NOAEL
Not stated in public reviews
Not reported in the public reviews. Reviewers summarise selectively, so this usually means it wasn't discussed publicly, not that it wasn't studied.
NOAEL / key findings
No NOAEL stated; no systemic toxicity in rats, only transient injection-site microscopic changes
“There were no local reactions and no signs of systemic toxicity including clinical pathology parameters, organ weights and macroscopic findings. The main related findings were transient microscopic changes at the injection sites, which is expected.”
