Dr Christina Parks, Cellular and Molecular Biologist explains that the ‘injections’ DO NOT and were never designed to prevent transmissions, only to attenuating symptoms of the alpha variant, which no longer exists. Worth a short watch.
The current science is indicating that the injected can transmit the virus just as much as the un-injected. Therefore, any ‘injection passport’ or mandate for work will not prevent transmission, so getting the injection, does not protect others, only the injected.
