MIT researchers have developed a novel way to record a patient’s vaccination history: storing the data in a pattern of quantum-dot dye, invisible to the naked eye, that is delivered under the skin at the same time as the vaccine.

Seems very patronizing idea tbh - “oh you can’t possibly know when you got the vaccine, we better make tattoo for you with invisible ink”

Also gates and koch foundation feeling very strongly about africa :soviet-hmm:
