Which of the following confers passive immunity


A vaccine may also confer passive immunity by providing antibodies or lymphocytes already made by an animal or human donor. Vaccines are usually administered by injection (parenteral administration), but some are given orally or even nasally (in the case of flu vaccine).

Which of the following is an example of passive immunity?

3) Passive immunity: Passive immunity is “borrowed” from another source and it lasts for a short time. For example, antibodies in a mother’s breast milk give a baby temporary immunity to diseases the mother has been exposed to.

Which of the following antibodies gives passive immunity?

Passive immunity is also provided through colostrum and breast milk, which contain IgA antibodies that are transferred to the gut of the infant, providing local protection against disease causing bacteria and viruses until the newborn can synthesize its own antibodies.

What are the types of passive immunity?

There are two types of passive immunity: artificial and natural.

Which of the following vaccine is used for passive immunization?

Passive Immunizations for AdultsDiseaseImmunizing AgentMumpsLive virus vaccinePertussisAdult preparation of pertussis antigens combined with tetanus and diphtheria toxoids (Tdap)Pneumococcal disease23-Valent polysaccharide vaccine (PPSV23)Pneumococcal conjugate vaccine (PCV13)22 more rows

Is IgM passive immunity?

Unlike IgG antibody which provides passive immunity to the fetus, IgM antibody is restricted from crossing the placenta due to its size. It is also the first antibody to respond during infection. IgM antibody earned the title of the “natural antibody” as it can bind to specific antigens without prior immunization.

Is immunoglobulin active or passive immunity?

Passive immunization with serum or globulin (antibodies) from immune persons has been used to prevent viral infections. Immunoglobulins, such as those used against hepatitis and respiratory syncytial virus, are effective only for prevention, not for treatment.

Which of the following is not an example of passive immunity?

Vaccines is the correct answer as it is NOT an example of passive immunity.

What is passive immunity dependent?

passive. Passive immunity depends upon. antibodies made by another organism.

Is an example of a passive immunization?

Artificial passive immunity comes from injected antibodies created within a different person or an animal. These antibody-containing preparations are termed antiserum. The rabies vaccine and snake antivenom are two examples of antiserums that yield passive immunity.

Is BCG a passive immunization?

Previous work has shown that the passive immunization with rabbit anti-Mycobacterium tuberculosis H37Rv antiserum of Mycobacterium bovis BCG-infected mice promotes the growth of bacilli in their spleen and induces a late production of antimycobacterial antibodies in their serum.

Which term is also known as passive immunity?

What term is also known as passive immunity? natural immunity.

Is tetanus toxoid a passive immunity?

Combined active-passive immunization with tetanus toxoid and 50 units TIGH gives a low level of passive immunity and stimulates early onset of active immunization. In combined active-passive immunization, adsorbed tetanus toxoid produced a significantly higher response than the fluid toxoid.


Passive immunity is the transfer of active humoral immunity of ready-made antibodies. Passive immunity can occur naturally, when maternal antibodies are transferred to the fetus through the placenta, and it can also be induced artificially, when high levels of antibodies specific to a pathogen or toxin (obtained from humans, horses, or other animals) are transferred to non-immune persons through blood products that contain antibodies, such as in immunoglobulin therapy or anti…

Naturally acquired

Maternal passive immunity is a type of naturally acquired passive immunity, and refers to antibody-mediated immunity conveyed to a fetus or infant by its mother. Naturally acquired passive immunity can be provided during pregnancy, and through breastfeeding. In humans, maternal antibodies (MatAb) are passed through the placenta to the fetus by an FcRn receptor on placental cells. This occurs predominately during the third trimester of pregnancy, and thus is often reduc…

Artificially acquired

Artificially acquired passive immunity is a short-term immunization achieved by the transfer of antibodies, which can be administered in several forms; as human or animal blood plasma or serum, as pooled human immunoglobulin for intravenous (IVIG) or intramuscular (IG) use, as high-titer human IVIG or IG from immunized donors or from donors recovering from the disease, and as monocl…

Passive transfer of cell-mediated immunity

The one exception to passive humoral immunity is the passive transfer of cell-mediated immunity, also called adoptive immunization which involves the transfer of mature circulating lymphocytes. It is rarely used in humans, and requires histocompatible (matched) donors, which are often difficult to find, and carries severe risks of graft-versus-host disease. This technique has been used in humans to treat certain diseases including some types of cancer and immunodeficiency. …

Advantages and disadvantages

An individual’s immune response of passive immunity is “faster than a vaccine” and can instill immunity in an individual that does not “respond to immunization”, often within hours or a few days. In addition to conferring passive immunities, breastfeeding has other lasting beneficial effects on the baby’s health, such as decreased risk of allergies and obesity.
A disadvantage to passive immunity is that producing antibodies in a laboratory is expensive an…
