Association between population percentage of complete vaccination series and the increases in cumulative hospitalization rate stratified by county metropolitan status, for selected time intervals in analysis of COVID-19 vaccination coverage and outcomes, Oklahoma, USA, February 2020–December 2021*
| Time interval | Metropolitan counties |
Nonmetropolitan counties |
|||
|---|---|---|---|---|---|
| Relative decrease for 1 percentage point increase in vaccination (95% CI) | p value | Relative decrease for 1 percentage point increase in vaccination (95% CI) | p value | ||
| Jan–Mar 2021 | –11.7% (–17.9% to –5.9%) | 0.0003 | –5.7% (–10.5% to –1.1%) | 0.017 | |
| Apr–Jun 2021 | –0.2% (–2.2% to 1.7%) | 0.816 | –0.9% (–4.1% to 2.2%) | 0.575 | |
| Jul–Dec 2021 | 1.1% (0.2%–1.9%) | 0.016 | –2.3% (–3.8% to –0.9%) | 0.001 | |
*Monthly data were modeled with (log-link) quasi-Poisson regression using the GAM function in R package “MGCV.” All models adjusted for averaged cumulative case rate as potential confounder
