"The BIO stock that I am heavily invested in..."
I can imagine that there will be many companies, public and private, which might have a hand in vaccine manufacturing and delivery if one or more vaccines are proven safe and effective. Supply chains... even vendors of equipment and supplies that might be used to manufacture and quality test, packaging... all of that.
I can also imagine that there might or will be tremendous pressure on the management teams and key players-- really all employees in, for example the publicly-traded companies that are known to be involved in the process. Cybersecurity and other security challenges, and of course SEC and related legal/regulatory pressures, et cetera.
And tremendous pressure on government officials involved in the ongoing process of development, trials, manufacturing ramp and distribution planning... and so on. Some of them will have "insider information" on an ongoing basis.
I guess this is all part of Operation Warp Speed... here is a link to the HHS website on this topic:

I note that some activities are public and are not (perhaps yet) mentioned in their summary, so for example there are more companies that have received funds for vaccine development than those listed.
I imagine the HR and legal departments of many of the companies involved might be very busy for quite a while.
