I will say that his vaccine training looked like it came right before M's hospitalisation and diabetes diagnosis (I hate that I even know that, but that's his fault). I don't think anyone would blame him if he focused on his own family at that time and volunteering took a back seat. HOWEVER, he took the accolades, he posed for the selfie and basked in the glory of being a "certified vaccinator", so I don't think a short update between then and now is too much to expect. Same with the other charitable stuff and good deeds he announces. If there's never any follow up, it's hard to accept that it's genuine.
