Bill Gates has pledged money for COVID-19 vaccine research, and him creating microchips for the purpose is a baseless story.
People opposing mandatory vaccinations picked up on the theme circulated by the rumor that Bill Gates was responsible for creating and spreading the virus as a means to grab control over the public health system.
Bill Gates has not developed a vaccine for COVID-19. In March 2020, the Bill & Melinda Gates Foundation has partnered with the Wellcome Trust and Mastercard Incorporated and pledged $125 million for research effort in collaboration with the Coalition for Epidemic Preparedness Innovation. There has been no confirmation of any kind of chip involved in the vaccine research.
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.
