Which of the following best describes a live-attenuated vaccine?

What is the main reason for the efficiency of IgM in binding antigens during a primary infection?

What is the primary function of the Western Blot technique in HIV testing?

What is the main advantage of the RIA method for thyroid hormone detection?

What conclusion can be drawn if an Ag-Ab complex dissociates when the pH is drastically lowered?

A woman receives a Hepatitis B vaccine containing only viral surface protein and requires a booster due to low immunogenicity. What type of vaccine is this?

A 45-year-old man receives a rabies vaccine derived from a virus that has been inactivated so it cannot replicate, but requires several booster doses. What type of vaccine is this?

A 9-month-old boy is brought to the clinic for measles immunization. The doctor explains that the vaccine works by mimicking natural infection because the virus used is still alive but has been weakened so it cannot cause disease. This vaccine stimulates long-term immunity. What type of vaccine is this?

A 22-year-old female comes for HPV vaccination. This vaccine contains a capsid protein structure resembling a virus but without DNA, making it safe to use. What type of vaccine is this?

A 32-year-old woman with SLE is taking immunosuppressants and wants to receive the influenza vaccine. The doctor explains that the vaccine response may be suboptimal because the medication suppresses B and T lymphocyte proliferation. What is the main mechanism?

A student conducts an ELISA test for anti-HIV antibodies. After adding the substrate, a color change occurs, indicating enzyme activity in the antigen-antibody complex. What is the mechanism involved?

A 27-year-old man is bitten by a snake and given antivenom. His symptoms improve quickly, but the doctor explains that the protection does not last long and does not form immune memory. What type of immunization is this?

A 5-year-old child receives a tetanus vaccine made from inactivated Clostridium tetani toxin. What type of vaccine is this?

The Widal test shows clumping when antigen is mixed with patient serum. What reaction is occurring?

A researcher wants to measure the strength of a single antibody paratope binding to a single antigen epitope. What parameter is being measured?

IgM increases in primary infection and can efficiently bind antigens due to having many binding sites. What is the reason for this efficiency?

What is the main function of the Western Blot in HIV testing?

A patient undergoes RIA for thyroid hormone. This method is very sensitive because it uses radioisotopes to detect very small amounts of antigen. What is the main advantage of this method?
