** Most major publishers have made all COVID-19 papers available open access. In general it is advisable to follow the Get it @ E/SMHS button to reach full text to avoid paywalls. Quick ways to connect to paywalled full text - bookmarklets and the LibKey Nomad browser plug-in (note the caveats - these are effective but not 100% effective).
