I think you'll essentially get your wish regardless. Assuming you're just a regular Joe citizen (not a healthcare worker, not someone high risk) you're highly unlikely to get access to the first run regardless. So, if phase 3 was a beta test, phase 4 will be millions of doses going to people as a sort of invite only full-release. So, as long as you're fine taking it 3-6 months or more after that, if no ill effects have befallen the millions of early adopters, then you're gold.
