This Premium Q&A, reviewed and published, features a real conversation between an iCliniq user and a physician.

Patient's Query

Hello doctor,

I am a 30-year-old male. I need some information about vaccination.

1. How does vaccination help in preventing the spread of infectious diseases?

2. What is the common vaccination schedule followed for kids?

3. Will it be more effective in preventing diseases in kids too?

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Vaccines are protein-based biological products that are administered parenterally or orally to children and adults to protect against serious, often deadly diseases.

Vaccines help the natural defense, i.e., the immune system, fight infections more efficiently by sparking the immune response to specific diseases. Then, if the same virus or bacteria invades the body in the future, the immune system will already know how to fight it.

Many feel that multiple vaccines will overload their child’s immune system. But the children are exposed to hundreds of bacteria and viruses every day. In fact, a common cold or sore throat will put a greater burden on the child’s immune system than vaccines.

Herd immunity: If enough individuals in the community are immunized against these diseases, the community can reach herd immunity. When this happens, diseases cannot spread easily from person to person because most people are immune.

Recommended vaccines, as per the CDC, include

1. Chickenpox (varicella) vaccine.

2. Diphtheria, tetanus, and acellular pertussis (DTaP) vaccine.

3. Hepatitis A (HepA) vaccine.

4. Haemophilus influenzae type b (Hib) vaccine.

5. Hepatitis B (HepB) vaccine.

6. Human papillomavirus (HPV) vaccine.

7. Influenza (flu) vaccine.

8. Measles, mumps, and rubella (MMR) vaccine.

9. Meningococcal (MenACWY, MenB) vaccines.

10. Pneumococcal (PCV13, PPSV23) vaccines.

11. Polio (IPV) vaccine.

12. Rotavirus (RV) vaccine.

I hope I have answered your question.

Let me know if I can assist you further.

Regards.
