About Vaccination

What is vaccination?

Vaccination protects children against serious diseases by stimulating the immune system against diseases germs.

How does vaccine immunity differ from natural immunity?

Normaly in most diseases the disease-gem enters the body produces the disease & the body mounts fighting power against the germ and lastly one recovers from the disease. Here immunity against disease is produced one has suffered from the disease. A vaccine is nothing but whole or part of the disease germ , which has been  processed or modified in such a way that it loses its capacity to produce disease but it can induce fighting power in the body when administered Hence by vaccination one develops  immunity without suffering from the disease.

 Myths Shattered

Myth: it is better to develop natural immunity than get vaccinated.

Fact: The difference between vaccination and natural infection is the price paid for immunity. The price paid for natural immunity (infection) is the physical, economical & mental agony the entire family goes through after one suffers from a disease. In comparison price paid for vaccination is negligible.

Myth by relying on vaccines, my child’s immune system becomes weak or does not develop at all.

Fact: No, vaccines do not weaken immune system, as generally thought. Vaccines are not ready made protection the body acts on vaccine germs and produces antibodies, which fight against disease germs when the child comes in contact with disease any time in future.

Myth Vaccines are known to cause serious side effects.

Fact: In most cases, Vaccines cause no side effects or only mild reactions such as fever or soreness at the Injection site. Very rarely, people experience more serious side effects like allergic reactions. Be sure to tell your doctor if you have health problems or known allergies to medications or food.

“Vaccines – Yes, But how many?

As you know-Prevention is always better than cure, fortunately, due to progress in vaccine science & Technology. It is possible to protect children against several serious diseases through vaccination normally a baby is exposed to millions of germs daily.It is much better to protect them against diseases through vaccination than let them be at risk & suffer.

Myth: My child does not require vaccines; as he/she is healthy, active& eats well.

Fact: Vaccination is intended to help keep healthy kids healthy, because vaccines work by protecting the body before disease strikes, if you wait until your child gets sick, it will be too late for the vaccine to work. The best time to immunize kids is when they’re healthy.

Myth: It’s OK to skip certain vaccines.

Fact: In general, skipping vaccines is not a good idea. This can leave your child vulnerable to potentially serious diseases that could otherwise be avoided. If you have reservations about any particular vaccine, discuss your concerns with your child’s doctor. If your child falls behind the standard vaccination schedule, catch-up vaccination is also available.

Myth: Vaccine may not be 100% effective: so why vaccinate?

Fact: Vaccines indeed are the most effective weapons we have against diseases. They work in 85% to 99% of cases. Smallpox has been eradicated from the face of earth & a dramatic reduction in the incidence of diseases like Polio, Diphtheria, Pertussis; Measles & Mumps are evidence of power of vaccines. Vaccine failure is rare & in such a case the disease is usually mild.

Myth: Vaccines are for babies only. There is no need to vaccinate after 2 to 4 years of age

Fact: Diseases continue to affect school going children, adolescents and adults. It is always better to keep your child protected Few vaccines (like DTP) do not provide lifelong protection. Protective efficacy of these vaccines wanes off over a period of time, so regular boosters are required.There are some new vaccines (like HPV) for adolescent girls to prevent Cervical Cancer. Some vaccines (like Flu) need regular vaccination as the virus keeps changing. For most of the vaccines age is not a barrier. Ask your doctor if you have missed any vaccine as you can always catch-up.

A friendly reminder for parents Adults need vaccination too! Check with your doctor to know what vaccines you might need. Your baby is counting on you!

Many children who contract pertussis have coughing spells that last four to eight weeks.The disease is most dangerous in infants. Two types of vaccines 1. Currently used DTP vaccines known as Whole-cell DTP vaccines. They are many decades old and are often associated with a range of side effects. 2 .The latest and technologically advanced Acellular DTP vaccines (Gentle DTP). They are as effective and come with significantly lesser side effects. Tdap vaccine: Protects kids 10 years and above against Diphtheria, Tetanus and Pertussis as immunity wanes following primary vaccination with DTP vaccine.

Hib Vaccine:Protects against meningitis (an infection of the covering of the brain and spinal cord), pneumonia (lung infection), epiglottises (a severe throat infection) and other serious infections caused by a type of bacteria called Haemophilus influenzae type b. The risk of disease is highest for children between 6 months and 2 years of age.

Pneumococcal Vaccine :Protects against pneumonia and meningitis leading to hospitalization and death caused by some strains of Streptococcus pneumoniae. Young children (younger than age 5 years) have the highest incidence of serious disease.
