I was fortunate enough to go into the laboratory recently — on vaccine-related coronavirus research that we hope might inform studies about the minimum dose of vaccine that can be used. This research is very much a tiny cog in a huge global wheel. By the time I had aliquoted the third tube of colourless liquid, I realized that it wasn’t the lab work that I missed while working from home — it was the people. This feeling was made worse because the work did not need the whole team to be present, so I was in a familiar place without the familiar people.
