Artis Ventures put together a list of all vaccines, treatments and diagnostics currently being worked on (for covid-19) – list of companies available in each category.
I looked for ETFs that carry most of those so that you don’t have to:
IHI (optionable, but low volume + holdings here etfdb.com/etf/IHI/#holdings )
IEIH (not optionable + holdings here etfdb.com/etf/IEIH/#holdings )
XLV (optionable + holdings here etfdb.com/etf/XLV/#holdings )
PJP (optionable + holdings here etfdb.com/etf/PJP/#holdings )
tl;dr Long either of them
