Forget about the lack of dangers out there, it is the lack of safety. Usually drugs have to be proven safe to become approved, this was not approved. Remind them that if they do this they are technically entering it for a trial phase. Ask them to look at animal models for medium long-term effects. Ask them why these vaccines never made it past animals trials and if maybe there was a good reason for that. Show them the data on Ivermectin. Alternatives also.
