On a side note... Im curious if Cal South will eventually require a vaccination card for play moving into late 2021? That will be the next question moving forward for a return to everything.
Because a couple vaccines have hit snags (in testing or manufacturing), the time line for getting the kids vaccine approved and widely circulated is looking a little more shaky. My friend who's with the AAP said initially late spring. Now it's looking like maybe spring-late spring for the 17-18 year olds, late spring to early summer for children with a risk profile (like the Downs, cancer and diabetic kids), mid summer,-mid fall for all other kids....assuming there are no more hiccups in testing and manufacturing. It will be hard for schools and sports orgs to mandate it if it isn't widely available.
BTW, the timeline for testing infants and pregnant women is also dubious. If you know anyone who really wants a vaccine but is childbearing age, might not be the best time to consider taking that step.
