It kills me that in my 20s I followed along with "science" and had my kids vaccinated. I'll never forget when my boys were about 10 and 6, the pediatrician gave me a new card for each boy with all their vaccines listed with the dates. They impressed upon me how important these cards were, guard them with my life, etc. They will one day be accepted as a form of ID. Didn't make sense to me since there's no photo on the card and my kids were in fact KIDS. But I guarded those cards. Now I wonder if they were trying to get vaccine passports off the ground back then.
