The effectiveness of the BNT162b2 and ChAdOx1 nCoV-19 vaccines against this variant has been unclear. We used a test-negative case-control design to estimate the effectiveness of vaccination against symptomatic disease caused by the delta variant or the predominant strain (B.1.1.7, or alpha variant) over the period that the delta variant began circulating. Variants were identified with the use of sequencing and on the basis of the spike ( ) gene status. Data on all symptomatic sequenced cases of Covid-19 in England were used to estimate the proportion of cases with either variant according to the patients' vaccination status. Effectiveness after one dose of vaccine (BNT162b2 or ChAdOx1 nCoV-19) was ny modest differences in vaccine effectiveness were noted with the delta variant as compared with the alpha variant after the receipt of two vaccine doses. Absolute differences in vaccine effectiveness were more marked after the receipt of the first dose. This finding would support efforts to maximize vaccine uptake with two doses among vulnerable populations. (Funded by Public Health England.). The aim of this study was to test if the e-learning activity that we developed could improve student nurses' knowledge of continence and mobility and whether or not students would find the style of learning beneficial. A quasi-experimental pre-post-test design was used to test if the continence and mobility e-learning activity could improve student nurses' knowledge about assessing and managing the needs of continence and mobility. An 18-item true/false knowledge of continence quiz was completed by 116 student nurses and a Likert
