Which of the following is not true about passive immunity?
Correct Answer
A. It generates memory
Explanation
Passive immunity is the transfer of antibodies from one individual to another, providing immediate but temporary protection. Unlike active immunity, which is generated by the individual's own immune response and can generate memory cells for long-term protection, passive immunity does not generate memory. Therefore, the statement "It generates memory" is not true about passive immunity.
2.
Which of the following are not considered active immunity?
Correct Answer
C. An Ideal vaccine whould cause no side effects, and only elicit the humoral immunity
Explanation
An ideal vaccine that causes no side effects and only elicits the humoral immunity is not considered active immunity because active immunity involves the body's immune system actively responding to an antigen and producing its own antibodies. In this case, the vaccine is only stimulating the production of antibodies without the need for the body to actively fight off the pathogen. Active immunity typically involves the production of both humoral and cellular immunity, whereas the given answer suggests that only humoral immunity is elicited.

Many people get vaccinated to protect themselves from disease, but they are also protecting others because they are unable to spread that same disease. Which of the following terns describes the idea that if most people in a population have immunity, it will limit the spread of a particular disease?
Correct Answer
B. Herd Immunity
Explanation
Herd immunity is the term that describes the idea that if most people in a population have immunity to a particular disease, it will limit the spread of that disease. This concept is based on the fact that when a large portion of the population is immune to a disease, it becomes difficult for the disease to spread because there are fewer susceptible individuals for it to infect. Therefore, even those who are unable to get vaccinated or are more susceptible to the disease can still be protected indirectly by the immunity of the majority.

A pateint with HIV needs to be caught up on their vaccinations. Which of the following are not an option?
Correct Answer
A. Live attenuated
Explanation
Live attenuated vaccines are not an option for a patient with HIV. Live attenuated vaccines contain weakened forms of the virus or bacteria, which can potentially cause an infection in individuals with weakened immune systems, such as those with HIV. These vaccines are generally not recommended for immunocompromised individuals due to the risk of developing the disease the vaccine is intended to prevent. Therefore, it is important to use alternative vaccine options, such as inactivated vaccines, capsular polysaccharides, inactivated toxins, or recombinant microbial agents, for patients with HIV.
5.
Which of the following is useful because less boosters are needed?
Correct Answer
C. Attenuated vaccine
Explanation
Attenuated vaccines are useful because they contain weakened forms of the pathogen, which can still stimulate an immune response but are less likely to cause disease. This means that fewer booster shots are needed compared to other types of vaccines. Inactivated vaccines, on the other hand, contain killed or inactivated pathogens, requiring multiple doses to achieve the desired immune response. Capsular polysaccharides and inactivated toxins are components of some vaccines, but they do not directly address the issue of needing fewer boosters. Recombinant microbial antigens refer to the use of genetically engineered components of a pathogen, but this does not necessarily reduce the need for boosters.
6.
Which of the following is an inactivated while organism vaccine?
Correct Answer(s)
A. Hepatitis A
D. Polio
Explanation
Hepatitis A and Polio are both examples of inactivated whole organism vaccines. Inactivated vaccines are made from killed or inactivated forms of the virus or bacteria. These vaccines are unable to cause the disease they are designed to protect against, but they still stimulate an immune response in the body. Hepatitis A and Polio vaccines are made by inactivating the virus that causes the diseases, making them safe for use in vaccination.
7.
Which of the following are inactivated exotoxins?
Correct Answer
C. DTap
Explanation
DTap stands for Diphtheria, Tetanus, and Pertussis vaccine. It contains inactivated exotoxins produced by the bacteria Corynebacterium diphtheriae and Bordetella pertussis. These toxins are rendered harmless through a process of inactivation, which allows them to stimulate the immune system without causing disease. The DTap vaccine is used to protect against diphtheria, tetanus, and pertussis infections.
8.
Which of the following can be given to a newborn?
Correct Answer
B. Hep B
Explanation
Hep B can be given to a newborn as it is a vaccine that protects against the hepatitis B virus. It is recommended to administer the Hep B vaccine to newborns within 24 hours of birth to prevent transmission of the virus from an infected mother to her baby. The vaccine helps in building immunity against hepatitis B, which can cause serious liver diseases if left untreated.
9.
You bring your child in for their 2 month appointment what shots will they recieve?
Correct Answer(s)
A. Rotavirus
C. DTap
E. IPV
Explanation
At the 2-month appointment, a child typically receives the Rotavirus, DTap, and IPV shots. The Rotavirus vaccine protects against a virus that causes severe diarrhea and vomiting in infants and young children. The DTap vaccine protects against diphtheria, tetanus, and pertussis (whooping cough). The IPV vaccine protects against polio. Varicella (chickenpox) and MMR (measles, mumps, and rubella) vaccines are usually given at a later age, not at the 2-month appointment.
10.
You bring your child in for their year old appointment, which vaccines will they recieve?
Correct Answer(s)
B. MMR
D. Varicella
E. PCV
Explanation
At the one-year-old appointment, the child will receive the MMR (Measles, Mumps, and Rubella) vaccine to protect against these contagious diseases. They will also receive the Varicella vaccine to prevent chickenpox and the PCV (Pneumococcal Conjugate Vaccine) to protect against pneumococcal infections. DTap (Diphtheria, Tetanus, and Pertussis) and HPV (Human Papillomavirus) vaccines are not typically administered at this age, so they will not be given during this appointment.
11.
Your child is about to enter kindergarten, what shots will they be recieving?
Correct Answer(s)
B. MMR
D. IPV
E. DTap
Explanation
When a child is about to enter kindergarten, they will typically receive the MMR (Measles, Mumps, and Rubella) vaccine, IPV (Inactivated Polio Vaccine), and DTap (Diphtheria, Tetanus, and Pertussis) vaccine. These vaccines are important for protecting the child against these diseases and ensuring their health and safety in a school environment. The Hep B (Hepatitis B) and PCV (Pneumococcal Conjugate Vaccine) shots are usually given earlier in infancy and may not be required again before kindergarten.
12.
Your daughter just turned 11 and you have always kept her accurate with her vaccines, what vaccine will she recieve?
Correct Answer(s)
B. Tdap
C. MCV
D. HPV
Explanation
At the age of 11, your daughter will receive the Tdap vaccine, which protects against tetanus, diphtheria, and pertussis (whooping cough). She will also receive the MCV (meningococcal conjugate) vaccine, which protects against meningococcal disease, and the HPV (human papillomavirus) vaccine, which protects against certain types of HPV that can cause cervical and other types of cancer. The HepB (hepatitis B) and HepA (hepatitis A) vaccines are typically administered earlier in childhood, so they would not be given at this age.
13.
Which of the following not a reason that adults should be immunized?
Correct Answer
B. If you have been vaccinated you never need boosters
14.
At what age should a patient recieve a zoster vaccine?
Correct Answer
B. 60
Explanation
The correct answer is 60 because the zoster vaccine is recommended for individuals who are 60 years of age or older. This vaccine helps to prevent shingles, a painful rash caused by the reactivation of the varicella-zoster virus, which also causes chickenpox. The risk of developing shingles increases with age, and the vaccine is most effective in older adults. Therefore, it is important for patients to receive the zoster vaccine at the recommended age of 60 or older to protect themselves against shingles.
15.
THe HPV vaccine was not available when you were 12, what is the optimal catch up age?
Correct Answer
C. 19-26
Explanation
The optimal catch-up age for the HPV vaccine is 19-26 because this age range is considered the most effective in preventing HPV infections. The vaccine is most effective when given before an individual becomes sexually active and is exposed to the virus. Therefore, it is recommended for individuals within this age range who may have missed getting vaccinated when they were younger.
