Six people in Australia mistakenly received an ultra-low dose of the COVID-19 vaccine due to incorrect preparation for the use of the Pfizer drug, the ABC TV channel reported.
Doctors assure that there is no threat to the vaccinated; they will be given additional vaccinations. However, Queensland health authorities are forced to contact 66 vaccinated people because they do not know exactly which of them are the six people with a low dose of the vaccine.
The reason for the incorrect actions of the doctors was called an “administrative error.” An investigation is being conducted to avoid such flaws in the future.
The doctors explained that the Pfizer vaccine required adding a salt solution to it in each vial so that six injections were obtained at the output.
