Claims that vaccines contain microchips used to track people are not supported by any credible scientific or medical evidence. Vaccines undergo extensive testing and regulatory review, and their full ingredient lists are publicly available through agencies like the FDA, EMA, and WHO. These ingredients typically include active components such as inactivated viruses, mRNA, or proteins, along with stabilizers, preservatives, and adjuvants. None of these formulations include electronic components of any kind. Microchips capable of tracking a person's location would require a power source, an antenna, and circuitry large enough to function—none of which could pass through a standard vaccine needle, which has an internal diameter far too small to accommodate such technology.

This misconception appears to have gained traction in 2020, partly due to misinterpreted comments about vaccine record-keeping and unrelated research into injectable biosensors, which are experimental and unrelated to commercial vaccines. Some conspiracy theories also falsely link this claim to patents or funding from technology companies, misrepresenting unrelated projects as evidence of hidden tracking devices.

Independent scientists, engineers, and fact-checkers have examined vaccine vials and syringes and found no evidence of embedded electronics. Existing tracking technologies, such as smartphones, already provide far more effective means of monitoring location than any hypothetical chip could offer through injection. The scientific consensus, supported by physics, engineering limitations, and transparent vaccine ingredient disclosures, firmly contradicts this claim.
