In any case, the only statement I found on health effects in the discussion/conclusion was "No toxic findings indicating liver damage were found in the rat repeated-dose toxicity test ( M2.6.6.3 )." but I don't speak Japanese and I'm sure using Google Translate is a very ineffective way of parsing research.
I highly recommend watching the whole stream.
But even then, not seeing an indication of risk within two orders of magnitude of covid itself.
There's no agreement on what's really happening. For example, clotting risk from the mRNA vaccines is supposedly the same as for the AstraZeneca vaccines, but governments across Europe already suspended the AZ vaccine due to clotting risks (supposedly). Therefore by implication, they would also consider the mRNA vaccines dangerous if their standards were consistent. Either the standards aren't consistent and the AZ blocks were political, or the claims that mRNA vaccines have similar clotting risks to AZ are wrong, but given the contradictory nature of many of the claims surrounding this topic - and given that you admitted you only just discovered some of the scientific discussion of the effects of mRNA vaccines - it may be worth dialing down your confidence slightly.

It might also move the risk/benefit of vaccinating children and people who already had COVID.
