In an effort to cordon off the epidemic, which has created unprecedented economic paralysis in the world, the nations of the world are currently betting on vaccinating their largest population against the emerging corona virus.

In the midst of this broad global movement, the person who took the vaccine has become labelled a "full vaccine," while experts say that talking about full vaccination against infection may be misleading and inaccurate, and may make individuals insane.

Despite being vaccinated with two doses of corona, earlier in October, former US Secretary of State Colin Powell died from complications of Covid 19.

But the former American politician and military, has been suffering from what is known as myeloma, a type of cancer that causes significant damage to the immune system in humans, even becoming able to produce only one type of antibody.

James Hamblin, a preventive medicine expert and lecturer professor of medicine at Yale University in Connecticut, US, explains that a large proportion of people suffering from this health disorder do not have enough immunity to corona infection when they take the vaccine.

It is noted that vaccines help to make the symptoms of COF19 much lighter, which means that the number of people who have to be hospitalized has decreased, and that deaths resulting from infection have been reduced.

According to the American health expert, James Hamblin, the term "full vaccine" is often being used inappropriately, stressing that accuracy is necessary in order to raise people's scientific and honest awareness and thus to make vaccination campaigns work.

The frenzied debate in the United States, for the time being, is about the feasibility of the third dose and who should benefit from it, with reports of significant antibody regression six months after the second dose.

The researcher spoke of a constant change in the knowledge of the full vaccine. Before American Centers for Disease Control and Prevention (CDC) standards said that a person is fully vaccinated when he passes two weeks after taking the second vaccine, and today there is an enhanced dose after months, and guidance may change over the next period.
