1. Active immunity may be gained by<br />a) Natural infection<br />b) Vaccines<br />c) Toxoids<br />d) All of these<br /><br />Answer: d) All of these<br /><br />Explanation: Active immunity can be acquired through natural infection, vaccination, or exposure to toxoids.<br /><br />2. Which of the following statements is not true regarding polio vaccines?<br />a) It is given at birth since there is no maternal antibodies transfer.<br />b) It induces intestinal immunity, besides producing antibodies in blood.<br />c) OPV coverage of 30% and above induces herd immunity.<br />d) It is simple to administer orally, well accepted by children and mothers.<br /><br />Answer: a) It is given at birth since there is no maternal antibodies transfer.<br /><br />Explanation: Polio vaccines are not given at birth; they are typically administered later in infancy.<br /><br />3. The following are priority activities for immunization programme except<br />a) Polio eradication<br />b) Accelerated disease control<br />c) Improving performance of routine Immunization<br />d) Non-Supplemental Immunization activities<br /><br />Answer: d) Non-Supplemental Immunization activities<br /><br />Explanation: Non-Supplemental Immunization activities are not considered a priority for immunization programs.<br /><br />4. The type of immunity that someone gets after acquiring an infection and successfully<br />surviving it is called __<br />a) Natural active immunity<br />b) Artificial active immunity<br />c) Natural passive immunity<br />d) Artificial passive immunity<br /><br />Answer: a) Natural active immunity<br /><br />Explanation: Natural active immunity is acquired when an individual survives an infection and develops immunity to the pathogen.<br /><br />5. Which one of the following is not an example of a viral live attenuated vaccine?<br />a) Oral polio vaccine (OPV)<br />b) BCG vaccine<br />c) Measles vaccine<br />d) Yellow fever<br /><br />Answer: c) Measles vaccine<br /><br />Explanation: The measles vaccine is not a viral live attenuated vaccine; it is typically administered as a killed vaccine.<br /><br />6. Methods of estimating vaccine needs includes:<br />a) Target population<br />b) Previous consumption<br />c) Size of immunization sessions<br />d) All of the above<br /><br />Answer: d) All of the above<br /><br />Explanation: Estimating vaccine needs involves considering the target population, previous consumption, and the size of immunization sessions.<br /><br />7. Poor utilization of immunization services may be caused by the following EXCEPT<br />a) Irregular supply of vaccines<br />b) High workload for staff<br />c) Friendly staff attitude<br />d) Poor scheduling of immunization sessions<br /><br />Answer: c) Friendly staff attitude<br /><br />Explanation: A friendly staff attitude is not a cause of poor utilization of immunization services; it actually contributes to better utilization.<br /><br />8. Write TRUE or FALSE for the following statements:<br />i) An immunization monitoring chart is a graphical presentation of a facility's performance<br /><br />Answer: TRUE<br /><br />Explanation: An immunization monitoring chart is indeed a graphical presentation of a facility's performance in terms of immunization coverage, coverage gaps, and other relevant metrics.
