Question

A person is injected with gamma globulin against hepatitis B. It is?
A.Naturally acquired passive immunity
B.Artificially acquired active immunity
C.Naturally acquired active immunity
D.Artificially acquired passive immunity

Answer 1

Hint: Hepatitis B vaccine is usually injected with 2, 3 or 4 shots. Babies should receive the first dose of hepatitis B vaccine when they are born, usually when they are 6 months old (sometimes it takes more than 6 months to complete the vaccination.

Complete answer:
Artificial passive immunity: The immediate but short-term immunity provided by the injection of antibodies (such as gamma globulin) not produced by the recipient cells. These antibodies develop in another individual or animal and are then injected into another individual.

Naturally acquired passive immunity: To occur during pregnancy, where certain antibodies are passed from the maternal blood to the fetal bloodstream in the form of IgG. Antibodies are transferred from one person to another in natural ways, such as the prenatal and postnatal relationship between mother and child.

Artificially acquired active immunity: can be induced by vaccines, which are substances that contain antigens. Vaccines can trigger a major response to the antigen without causing disease symptoms (see Vaccinations.

Naturally acquired passive immunity: To occur during pregnancy, where certain antibodies are passed from the maternal blood to the fetal bloodstream in the form of IgG. Antibodies are transferred from one person to another in natural ways, such as the prenatal and postnatal relationship between mother and child.

Hence the correct answer is OPTION(D)

Note: Passive immunity can be provided when someone acquires antibodies against a certain disease, instead of producing antibodies through their own immune system. Newborn babies gain passive immunity from their mothers through the placenta.
