The COVID pandemic has required fundamental reassessment of the delivery of courses in the health sciences. This annotated bibliography of 237 items is intended to provide a starting point for assessing which modes of delivery have proved most effective. It builds on the earlier NIDA resource discovery "The impact of Science Literacy delivery methods - what works?" (2017-2020). It was produced as an initial activity for a planned research project "Impact Evaluation for e-Learning in Science and Health Literacy". Entries are drawn mainly from PubMed, ERIC and GoogleScholar, and contain brief annotations extracted from articles' abstracts, introductions or conclusions. They are arranged under the following headings: General; Continuing Education and Training; Fake News, Disinformation, and Digital Literacies; Nursing; Patients and Service Delivery; Peer Learning; School Health; Social Media Applications and Mobile Learning; and Specific Morbidities and Conditions Applications. The entries cover experience world-wide in English-language sources. A final section of Concluding Observations identifies some common themes covering design and content considerations, study support, and study environment.
