Child vaccines are supposed to lead us to the end of the tunnel. But they won’t if we let too many people off the train.

Before the pandemic, I had a tiny bunch of gray hair, so few that I could tear it off. Now they are woven into my brown hair. Once, when my 7-year-old son was younger, he asked me if white hair came from a heart attack and I told him “sometimes.” He now calls mine my “corruptions”. I am not correcting him because somehow that explanation feels more accurate than the scientific one.
