Got a fat reading pile I haven't yet tucked into. Part of my plans too. However, did manage to get into my bank of past webinars/podcasts to watch and listen: Things like MEASURE, CGD, Development Drums.
LSHTM will be have some decent public health, pandemic related content in the next month I'm sure. Past ones here:https://vimeo.com/lshtm
There are also some short courses one could tick off in a week or two on FutureLearn, edX, Coursera etc.
