Covid-19: Experts say one vaccine dose enough for five people

Given the acute shortage of Covid-19 vaccines, one way to ramp up the vaccination programme is by providing a smaller quantity of the vaccine in an intradermal (ID) way, said experts. This means injecting 0.1ml into the skin, which is a fifth of the volume of the current dose of 0.5ml given intramuscularly in the shoulder. In short, a 0.5ml dose now given to one recipient will be able to vaccinate five persons by the intradermal route.
