Question

An antibiotic is not useful against a virus whereas a vaccine is. Which one of the following is the most appropriate reason for this ?
1. An antibiotic can break RNA only, whereas virus has DNA.
2. ​An antibiotic is a carbohydrate in its chemical nature, whereas a vaccine is a protein which works well to kill a virus.
3. Only  a vaccine can break the genetic material of a virus.
4. A virus does not use biochemical pathways ​​which can be blocked by an antibiotic. But a vaccine can boost an immune system to fight the virus.

Answer 1

Correct Answer - Option 4 : A virus does not use biochemical pathways ​​which can be blocked by an antibiotic. But a vaccine can boost an immune system to fight the virus.

The correct answer is A virus does not use biochemical pathways ​​which can be blocked by an antibiotic. But a vaccine can boost an immune system to fight the virus.

• Viruses are different from bacteria they have a different structure and a different way of surviving.
• The viruses don't have cell walls that can be attacked by antibiotics instead they are surrounded by a protective protein coat.
• Vaccines can help limit the spread of antibiotic resistance.
• The global increase in disease caused by drug-resistant bacteria, due to overuse and misuse of antibiotics, is a major public health concern.
• It is more difficult and costly to treat antibiotic-resistant infections and people do not always recover.

•  FACTORS INFLUENCING VACCINE RESPONSES:
  • ​Age is an important factor that influences vaccine responses, especially in the extreme ages of life.
  • Infants should receive immunizations as early as possible to minimize the time that they are susceptible to infections.
  • However, neonates have a lower level of antibody production and, moreover, passively acquired maternal antibodies interfere with vaccine responses.
• Perinatal Host Factors:
  • ​Gestational age.
  • Birth weight.
  • Breastfeeding.
  • Maternal antibodies.
  • Maternal infections during pregnancy.
  • Other maternal factors.
