This is an interesting thought....everyone I know who has gotten the vaccine has been handed those vaccine cards, then told on the card when to come back. All on paper and hand written. Doc is basically taking that simplistic thought and make it even more organized and simplistic, by entering all the information in the computer for providers and pharmacies to keep track off all in one database for over 50,000 pharmacies to use. Pharmacies like CVS, Rite Aid, Wal Mart and so on. I CANT Imagine he is letting them all use it for free. WOW AMAZING STUFF DOC.
