Doses Reported By State Systems and Hospital Lists, By Week of Vaccine Shipment Arrival
The reporting of vaccine administration data into the state systems is consistently an under-count of actual number of doses administered locally, due to incomplete and delayed reporting into these systems. In order to have a more reliable estimate of vaccine administration by facilities in LA County, we have instituted a weekly survey of administering facilities, through which we are able to obtain self-reported data for number of vaccines administered by each facility. We have presented the cumulative number of doses administered using both sources of data.
| Year | Arrival week | Weekly Doses Arriving | Cumulative Doses in County | Cumulative # of Doses Administered | % of Doses Administered |
| 2020 | 14-Dec | 82,875 | 82,875 | 63,566 (as of 12/24) | 76.7 |
| 2020 | 21-Dec | 165,350 | 248,225 | 114,522 (as of 12/31) | 46.1 |
| 2020 | 28-Dec | 109,325 | 357,550 | 217,831 (as of 1/7) | 60.9 |
| 2021 | 4-Jan | 133,575 | 491,125 | 344,563 (as of 1/14) | 70.2 |
| 2021 | 11-Jan | 193,950 | 685,075 | 441,430 (as of 1/21) | 64.4 |
| 2021 | 18-Jan | 168,575 | 853,650 | Pending | Pending |
**Cumulative number of doses administered is underreported due to reporting delay and challenges using State systems. Cumulative doses administered 10 days after the week of arrival accounts for reporting delay and the time needed for distribution, appointment scheduling, and vaccine administration.
