Flublok: genotox, carcinogenicity and repro: done or skipped?

influenza vaccine, recombinant hemagglutinin · Influenza HA
Genotoxicity
Not conducted (not normally required for viral vaccines; no adjuvant)
“No genotoxicity and carcinogenicity studies were carried out in line with relevant guidelines. Studies evaluating genotoxicity and carcinogenicity are normally not required for viral vaccines.”
✓ VerifiedEMA assessment report, p. 29Source ↗
Carcinogenicity
Not conducted (not normally required for viral vaccines; no adjuvant or novel excipients)
“Studies evaluating genotoxicity and carcinogenicity are normally not required for viral vaccines. Since no adjuvants or novel excipients are used in this product absence of those studies is considered acceptable.”

Reproductive & developmental
Rat fertility, embryo-fetal and early postnatal study (three IM doses, pre-mating and GD6): no adverse effects
“In DART study conducted in female rats, three IM injections (31 and 12 days before mating and on Gestation Day 6) of RIV3 did not induce maternal toxicity, and there were no adverse effects on mating performance or fertility, embryo-foetal development (including an evaluation of teratogenicity) and an early post-natal development.”

Safety pharmacology
Dedicated single-dose SC studies: dog cardiovascular, rat respiratory and CNS; no effects
“Results of safety pharmacology studies showed that a single SC injection with RIV3 did not adversely affect the blood pressure, heart rate, ECG parameters (in beagle dogs), respiratory parameters (in rats) as well as FOB, locomotor activity or body temperature (in rats).”
