Question

Which of the following vaccines are vaccinated to babies at the age of one and a half, two and a half, and three and a half months?
A. DPT-Hib and polio
B. Polio and BCG
C. BCG and DPT
D. BCG and hepatitis B
E. Polio and DPT, hepatitis B

Answer 1

Hint: Vaccines are medications that consist of weaker or attenuated versions of the disease-causing microorganisms. The immune cells remember their encounter, so that when a real pathogen invades they can effectively remove it from the body.

Complete answer:
Vaccines are simply the weaker versions of the real disease. These are injected to enhance adaptive immunity. Once vaccinated, the person’s immune cells fight the weaker versions of the disease. The memory cells of the immune system will record this encounter and will remember the mechanism they used to fight it. This same mechanism will be employed if in the future the vaccinated individual gets the real disease. Babies at age of one and a half, two and a half, and three and half months are given a combination of vaccines. As they are vulnerable to many life-threatening diseases they receive periodic vaccinations. The major threats include Hepatitis B for which the hepatitis B vaccine is administered. The second is the polio vaccine for the prevention of poliomyelitis. The third major threat is diphtheria, pertussis, and tetanus for which the DPT vaccine is given. The BCG is for the prevention of tuberculosis and DPT-Hib is an optional vaccine in the Indian continent due to lower infection rates. It is a combination of diphtheria, pertussis, tetanus, and influenza B virus. They are administered optionally. BCG is recommended for patients of tuberculosis requiring it as a cure around 16 to 35 years of age.

Therefore, the right answer is option E.

Note: Vaccines are like immune enhancers. Viral diseases are very less affected by any oral administration. But vaccines present a fake virus-infected scenario in the body that makes the immune system ready to fight and kill the real virus whenever encountered. Thus, vaccination should be done regularly as a preventive measure to get deadly infections.
