What you need to know about “Children’s Vaccinations”

Question 1: What is Vaccination?

Our body is protected from invasions of bacteria, viruses and fungi by a defense mechanism called immunity. This army is manned by soldiers (white blood cells) which will produce weapons and ammunition against the germs (immunoglobulin,anti-toxin) to destroy them. Unfortunately, when faced with virulent germs, sometimes the immune system is not strong enough or has not been well prepared to fight off the infections; the body will then succumb to the infections.

Vaccination or immunization is and ingenious way of getting the body primed and loaded with ammunition to fight off infections even before they happen. The immune system is exposed to a harmless substance that mimics the dangerous bacteria or viruses. This harmless substance is modified in such a way that it will cause the body’s immune system to produce antibodies or anti-toxins against the bacteria or viruses that it is mimicking but will not harm the body at all. In the future when the body is exposed to the real harmful organism, the immune system is all ready to send off the soldiers/ammunition that have been prepared or assembled during the ‘mock run’ ie. the vaccination.

Questions 2: Are Vaccinations harmless?

Most vaccinations are harmless. However, during the process of producing antibodies, the body can elicit certain minor unwanted reactions. Majority of the side effects are harmless for example. fever, local redness and pain over the injection site, rash, transient fussiness and off feed.

However in rare cases (less than 1 in 25000 cases), a more severe reaction called Anaphylactic or Anaphylactoid reaction can occur. This presents as collapse, convulsions, sudden paleness and absence of pulse soon after vaccination. This reaction should be treated immediately by qualified medical personnel with drugs that should always be available when vaccinations are being given.

Question 3: Can a person receive too many injections?

No. The body can receive and produce antibodies against a myriad of vaccines. There is no limit to the number of vaccines that a person can receive, as a person is exposed to millions of bacteria and viruses in real life and therefore has been designed to cope with that. The vaccine can be given together either in combination or separately at different sites of the body (e.g. right thigh, left thigh, right arm or left arm). However, should the vaccines be given at different times, there should a time lapse of at least 3 weeks in between vaccinations.

Question 4: What are the common vaccinations that are being given to the children in this country?
