The Medical Library Association is curating a collection of COVID-19 search strategies for various topics and databases. You can find these search strategies here: COVID-19 Literature Searches
PubMed Clinical Queries now has a filter for COVID 19 articles on the main search page. This allows you to limit search results to COVID-19 articles: PubMed Clinical Queries
Here are search strategies created by Becker librarians you can copy/paste into databases to find COVID-19 studies. You can combine (using AND) these with other concepts to view articles about specific topics related to COVID-19 (e.g. AND COVID-19 terms with vaccine terms to find studies about vaccine research).
