The COVID-19 vaccines do not contain microchips.
Some social media users have falsely claimed that COVID-19 vaccines deliver a microchip into the body. Videos of people sticking magnets to their arms have furthered the circulation of this claim. But none of the available COVID-19 vaccinations (Pfizer, Moderna, Johnson, and Johnson, or AstraZeneca) list any metal-based ingredients, and none deliver microchips.
Some social media posts show a photo of a microchip inside a needle's tip, with a caption implying a link to the COVID-19 vaccine. The image used in social media posts is Figure 1D from the microtechnology study conducted by Columbia University researchers. The research was published in Science Advances on May 7, 2021. The image relates to Columbia engineers who have developed the smallest single-chip injectable into the human body to monitor medical conditions. According to the researchers, the device, which measures 0.1 cubic millimeters and can be injected with a hypodermic needle, is the smallest single-chip system of its kind. However, this technology is yet to be approved for human use and is not used in COVID vaccines.
The U.S. government has not been tracking people by injecting microchips in COVID-19 vaccines, says the CDC. On Twitter, the Rhode Island Department of Health wrote that COVID-19 vaccines do not change people's personalities, aid the growth of a third eye, or change DNA. The Rhode Island Department of Health that COVID vaccines are definitely microchip-free.
Pfizer published its vaccine ingredients when the microchip-in-vaccines rumors resurfaced. The Pfizer vaccine contains 10 ingredients, and one active ingredient in the vaccine is a molecule called messenger RNA, or mRNA, lipids, salts, and sucrose or sugar.
The COVID-19 pandemic has given rise to a lot of potentially dangerous misinformation. For reliable advice on COVID-19 including symptoms, prevention and available treatment, please refer to the World Health Organisation or your national healthcare authority.
