Makeshift vaccination sites and mass vaccinations have been the response to the pandemic until now. The consequence of this is often overworked medical staff and large amounts of hazardous waste caused by disposable syringe use. IMO proposes a more sustainable vaccination technology; spraying the vaccine onto the skin. The vaccine is absorbed slowly into the skin thus giving the body enough time to get used to it, avoiding shock reactions, and reducing the need for follow-up monitoring. The vaccine can be applied anywhere on the skin which allows also untrained staff to administer vaccinations.
