The tests can determine whether or not an individual has had the virus in the past by looking for signs of the immune response. And the type of antibodies that vaccines trigger are not detectable by tests designed to tell who has already infected, so the blood test likely won't confirm that someone has been vaccinated (functioning like a pseudo-immunity passport). It is this second class that provides the most interest. Daily vaccine distribution in the country slowly increased from December to mid-April. Almost half of Americans have received at least one shot of the COVID-19 vaccine as of Wednesday afternoon.
The tests can determine whether or not an individuals has had the virus in the past by looking for signs of the pImmunity along with visible red blood.
