The state Department of Health Services released new COVID-19 data for the first time in three months this week surrounding the differences in illness, hospitalization and death rates among residents not fully vaccinated and those fully vaccinated.
The DHS found that in March, those not fully vaccinated were being diagnosed with COVID-19 at a similar rate as those who were fully vaccinated. To be exact, people not fully vaccinated were diagnosed with COVID-19 at a rate 1.1 times higher than people who were fully vaccinated. The state attributes this finding to the omicron variant.
Differences in hospitalization and death rates were also significantly smaller than previous months. According to March data, people not fully vaccinated were hospitalized at a rate 2.4 times higher than fully vaccinated people, and they died at a 3.4 times higher rate.
When the DHS last reported illness after vaccination data it was in January with December data, it found residents not fully vaccinated were 10 times more likely to be hospitalized and 14 times more likely to die from COVID-19 than the fully vaccinated.
The state also provided data for January and February and it found that people not fully vaccinated were diagnosed with COVID-19 at a rate 1.3 times higher than people who were fully vaccinated in those two months.
In January, people not fully vaccinated were 3.4 times more likely to be hospitalized with COVID-19 and 7.4 times more likely to die from it.
In February, people not fully vaccinated were 2.8 times more likely to be hospitalized with COVID-19 and 5.5 times more likely to die from it.
The newly added data for January, February and March 2022 comes after delays from “technical difficulties” with how the data was gathered and stored.

Variant case sequencing
State and private labs regularly do further tests on a portion of positive COVID-19 samples to find the prevalence of different variants of the virus. The numbers below are just a fraction of the total number of variant cases.
Omicron variant was identified in more than 99% of tests sequenced during the week starting March 13. “Other” variants were identified in less than 1% of tests sequenced.
