COVID-19 vaccine syringe is designed to have RFID microchips, on the outside, but contains no tracker on the inside. However, the chip is optional.
The syringes' product page states that Apiject will provide attachments and services that administer the drug product once it is packaged in BFS containers. These include needle hubs, auto-disable jackets, anti-counterfeit security, among others. The anti-counterfeit security contains RFID/ NFC tags, which will ensure the authenticity of the drug dose.
Further, in an interview, Jay Walker, CEO of ApiJect Systems, clarified that the chip does not carry any personal information. He stated that the chip is designed similar to a bar code and is optional. Walker also revealed that the U.S. government has not yet decided whether they would use it.
So it is clear COVID-19 vaccine syringes could contain RFID microchips on the outside label and won't be implanted into the individual's body that receives the vaccine.
