Bill is laughing about "barcodes" (harking back to Jews and the IBM Holocaust machine) but here is a GAVI program he certainly knows about:

In 2018, Mastercard’s startup engagement program Start Path approached the company to discuss how it might contribute to immunization recording and tracking for children in remote regions. Trust Stamp is now working with Mastercard to integrate its digital identity capabilities into Mastercard’s Wellness Pass solution, which will be launched alongside Gavi, the Vaccine Alliance, in West Africa.

and this part gets more interesting:

Trust Stamp is also exploring new ways to commercialize the hash. The company, which has more than doubled its staff in the past year and has received an investment from Mastercard, is working to provide travel and insurance companies with touchless identity and real estate agents a way to identify criminals prior to appointments. They are also talking to correctional systems about providing identification for people on parole without making them pay for pricey ankle bracelets that monitor their every move."

So they're pairing monetary purchases, with vaccines, using a hash code (digital barcode). And they're doing it on poor Africans (again). It can be used by any agent to force identify you and also replaces ankle monitors?

Is it yet another IBM Holocaust system from the Malthusian Eugenicists?

It quacks like a Duck.

If you're familiar with Plato's theory of forms, this one is an oldie. It's called "Mark of the Beast".
