Understanding Immunisation
Unlock Audio Lesson
Welcome class! Today, we’re going to dive into the topic of immunisation. Can anyone tell me what immunisation means?
Is it about vaccines that help us not get sick?
Exactly! Immunisation is a process by which a person is made immune, or resistant, to an infectious disease, typically by the administration of a vaccine. A vaccine contains an inactive form of a bacteria or virus, which ensures that we don't get the actual disease.
So the vaccine just trains our body?
Yes! It teaches our immune system to recognize and fight off the actual pathogens should we encounter them in the future. Remember this: 'Vaccines are like dress rehearsals for our immune system!'
What are some vaccines we need to take?
Great question! We'll go over that in our upcoming discussions, but just keep in mind that immunisation is crucial for preventing serious illnesses.
To recap, immunisation trains your body to fight infections without making you sick. Let's move on to how vaccines are implemented in childhood.
National Immunisation Schedule
Unlock Audio Lesson
Now that we understand what immunisation is, let's look at the National Immunisation Schedule. Who can tell me why this schedule is important?
Because it tells us when to get vaccinated!
Absolutely! This schedule recommends specific vaccines at certain ages to provide the best protection. For instance, at birth, children receive the BCG, OPV, and Hepatitis B vaccines. Can anyone recall what BCG protects against?
I believe it’s for tuberculosis?
Correct! And there are follow-up doses at 6, 10, and 14 weeks. It's crucial to stay on schedule. This is how we ensure maximum immunity against various diseases. It's like having a shield ready before the battle begins!
To summarize, immunisation schedules help us keep track of when to get important vaccines, protecting children from serious diseases.
Nutrition and Immunisation Relationship
Unlock Audio Lesson
Now, let’s connect nutrition and immunisation. Can anyone suggest how nutrition might affect a child's health in relation to vaccines?
If a child is malnourished, they might not respond well to vaccines?
Exactly! Good nutrition strengthens our immune system, which is essential for vaccines to be effective. If a child is malnourished, they’re more vulnerable to diseases, and the vaccines may not work as well.
So, we need to eat healthy to be strong and let the vaccines work!
Yes! Adequate nutrition includes proper vitamins and minerals that promote the production of antibodies. We need to ensure a balanced diet so vaccines can do their job effectively!
To conclude, nutrition is just as important as vaccines in protecting children from communicable diseases, making it a combined effort for good health.

This section emphasizes the importance of immunisation in child health, illustrating how vaccines work and providing the National Immunisation Schedule recommended by the ICMR. These vaccines protect children from serious illnesses and diseases.
Detailed
Detailed Summary
Immunisation plays a vital role in ensuring good health and well-being, particularly among children. It is not solely dependent on adequate nutrition. The concept relies on the use of vaccines containing inactive forms of bacteria, viruses, or toxins, which are administered to children. These inactive components do not cause infection but instead trigger the immune system to produce antibodies. When children are later exposed to the actual germ, their immune system can effectively respond to and eliminate the threat.
Key Points:
- Vaccine Action: Vaccines work by introducing inactive pathogens, prompting the immune system to create specific antibodies without causing diseases.
- National Immunisation Schedule: The section outlines the immunisation schedule recommended by the Indian Council of Medical Research (ICMR), detailing the vaccines to be administered at specific ages to maximize disease prevention. The schedule includes vaccines for:
- Birth: BCG, OPV, HEP B
- 6 weeks, 10 weeks, 14 weeks: OPV, PENTA (which includes DPT, HEP B, HiB)
- 9 months: MR (Measles, Rubella)
- Consequences of Malnutrition: The text further notes that poor nutrition exacerbates the risk of diseases in children, particularly in rural and tribal areas. Malnutrition is closely related to an increased incidence of infections, impacting child health significantly.
- Need for Public Health Awareness: It discusses how a lack of health care access, literacy, and knowledge of nutrition can lead to malnutrition and compromise health outcomes.
This section highlights that through proper immunisation practices, children can develop lifelong immunity against communicable diseases, significantly reducing mortality and morbidity rates.

Good health and well-being are not entirely dependent on good nutrition. We all are aware of the role of immunisation in protecting children from various diseases.
Detailed Explanation
Immunisation is crucial for maintaining the health of children. While good nutrition is important, it alone is not sufficient to ensure children are protected from diseases. Immunisation helps create immunity against specific illnesses, acting as a preventive measure to reduce the incidence of serious diseases.
Examples & Analogies
Think of immunisation like having a strong fence around a garden. While you may provide the plants with good soil and water (nutrition), the fence (immunisation) protects them against pests and diseases that can harm them.
How Vaccines Work
Unlock Audio Book

You may be interested in knowing how immunisation protects children from diseases. A vaccine that contains an inactive form of a bacterium/virus/toxin made by the germ is injected in the child. Being inactive it does not cause infections but induces white blood cells to produce antibodies. These antibodies then kill the germs when they attack the child’s system.
Detailed Explanation
When a child receives a vaccine, a small amount of an inactive or harmless form of the germ is introduced into their body. This does not cause disease but stimulates the immune system to create antibodies, which are special proteins that help the body fight infections. If the real germ invades later, the body is prepared to combat it quickly and effectively.
Examples & Analogies
Imagine your body as a castle, and vaccines as training for the guards. The inactive germs are like practice dummies that the guards train against. Once the real threat appears, the guards are ready and know exactly what to do to defend the castle.

Table 3: National Immunisation Schedule (Recommended by ICMR)
Age of the child Vaccine:
Birth: BCG, OPV, HEP B
6 weeks: OPV, PENTA (DPT, HEP B, HiB)
10 weeks: OPV, PENTA (DPT, HEP B, HiB)
14 weeks: OPV, PENTA (DPT, HEP B, HiB)
9 months: MR (Measles, Rubella)
Detailed Explanation
The National Immunisation Schedule outlines specific ages when children should receive various vaccines to protect them from diseases. This includes vaccinations at birth, 6 weeks, 10 weeks, 14 weeks, and 9 months, ensuring that children are inoculated at the right stages in their early development.
Examples & Analogies
Think of the immunisation schedule as a timetable for a sports team, where each player (vaccine) needs to practice at specific times to be ready for the big game (protecting against diseases). Following this schedule helps ensure every child has the best defense against illnesses.
Common Health Problems Related to Immunisation

Common health and nutrition problems in infants and young children include malnutrition and infections. We have learnt how malnutrition and infections are interrelated. In fact, malnutrition is a national problem.
Detailed Explanation
Malnutrition can increase the risk of infections in children because it weakens their immune system. Without proper nutrition, children are more susceptible to diseases. This makes it even more crucial for children to receive their vaccinations, as these diseases can have severe consequences, particularly in those who are already vulnerable.
Examples & Analogies
Think of malnutrition as a shortage of supplies in a war. If the soldiers (children) don't have enough food (nutrition), they won't be strong enough to fight effectively against enemy attacks (infections). This highlights the importance of both proper nutrition and immunisation in keeping children healthy.
Role of Community and Healthcare Access
Unlock Audio Book

In rural and tribal areas, factors such as poor access to health centres, climatic conditions, certain local customs, and use of untested traditional methods of treatment increase the child’s susceptibility to infectious diseases.
Detailed Explanation
Access to healthcare services is essential for effective immunisation programs. In rural areas, many families may not have the means to reach health centres or may rely on traditional remedies that are not scientifically supported. This can lead to lower vaccination rates and higher vulnerability to infectious diseases, underlining the need for community outreach and education about the importance of immunisation.
Examples & Analogies
Imagine a remote village where the nearest school is miles away. Without a bus or easy access to transport, many children won’t attend regularly. Similarly, if families in rural areas can’t easily reach healthcare facilities, their children may miss out on crucial vaccinations, leaving them unprotected against diseases.
