New cases in LA are flat, even as vaccinations surge


We try to keep you up to date by compiling a weekly rundown of the most important local data on vaccinations, new cases, and hospitalizations across Los Angeles County. 



Vaccine doses administered in Los Angeles County by week

For the second week in a row, Los Angeles County broke its own record for delivering vaccinations. Between March 18-24, the county administered 559,840 new vaccinations, 174,554 of which were second doses. In addition, a total of 67,016 Johnson & Johnson vaccine doses have been administered, meaning those vaccinated will not require a second dose. In total, Los Angeles County is nearing 4 million vaccinations, at 3,794,829.


These figures are a slight increase from last week’s vaccination data. In the period of March 11-17, the county administered 493,412 new vaccines, 158,267 of which were second doses. At the time, last week had set a record for the county. Over the past two weeks alone, weekly vaccinations have increased by 71.7%.


Vaccine distribution is largely dependent on the supplies the county receives. In a March 26 press release, the Los Angeles County Department of Public Health noted that it expects to receive 21% more doses than it did the previous week. While this is still under the county’s capable capacity for vaccine distribution, the increase in supply is a strong indicator of the county’s ability to keep the momentum going.

Unlike new cases, hospitalizations have remained on a steady decline. On Saturday, March 27, Los Angeles reported a new low for hospitalizations, at 676. The last time hospitalizations were this low was Oct. 5. This is also an 89.1% decrease from two months prior, when there were 6,213 reported hospitalizations on Jan. 27. While this is great progress, hospitalizations marginally increased on March 24-25, indicating that we may start seeing a plateau in hospitalizations, as well as cases.
