ABSTRACT
This cross-sectional study examined the relationship between COVID-19 vaccination rates and infection incidence rates within the Municipality of Anchorage, Alaska. Data retrieved from the Alaska COVID-19 Information Hub covered 11 four-week periods, from October 10, 2020, to August 19, 2021. Spearman’s rank correlation coefficient test revealed a strong negative monotonic relationship, while scatterplot analysis confirmed a high negative correlation. The statistical analysis demonstrated that the probability of the null hypothesis occurring by chance was significantly low, leading to its rejection in favor of the alternative hypothesis. The findings provide clear evidence that COVID-19 vaccines effectively reduce the spread of SARS-CoV-2 infections; as vaccination rates increase, infection rates decrease. However, with 44.3% of the Anchorage population still unvaccinated, achieving the Municipality’s 70% vaccination goal is unlikely without the implementation of additional public health mandates and policies to mitigate the spread of COVID-19.
