ok so it seems it made sense at first: 1a was healthcare personnel; 1b was essential workers / 75+; 1c was 65+ / people with comorbidities. by the original definition I should be in phase 2. tho for clarity we could have just called them phases 1, 2, 3 & 4 https://www.cdc.gov/coronavirus/2019-ncov/vaccines/recommendations.html
