So, the bolded may be relevant to anyone in CA waiting for April 1/15. If someone in your family has already been eligible to be vaccinated, you are ALSO eligible by extension!
This is from my city's Mayor:
Covid-19 Update 3/25/21:
OC now has 1.2 million people who are vaccinated with at least their first dose. We are the 3rd County in the state to get this far for our population.
As of today, the state announced that when a person in the applicable tiers gets vaccinated, anyone 16+ in their family may get vaccinated too.
Beginning April 1st, all ages 50+ are eligible to get vaccinated. Beginning April 15th, all ages 16+ are eligible to get vaccinated.
