Cons of Childhood Vaccinations

While the immunization programmes are continuing, from time to time, there can be certain unwanted reactions or effects as well as vaccination failures for us to deal with. At the same time, when certain diseases are under control or even unheard-of in the present context, people wonder the need for continuation of the vaccination. All these have lead to certain amount of ‘myth building’ and they have added spice to the possible ‘unwanted effects of childhood vaccination’.

Coverage of the vaccine:

One of the queries or cons that creep up in childhood vaccination practices is its inability to cover the population at 100%. Thus, many vaccines will have an effective range of around 85 – 95% and in certain instances a child who was vaccinated for a particular illness might develop the same disease later on. This is considered to be one drawback in the vaccination process but, given the wider coverage of the population as well as the reduced incidence of major illness among the children who develop the disease makes it worthwhile to get the vaccine rather than not receiving the vaccine at all.

Is it necessary?

When certain diseases seem to disappear following mass vaccinations, people argue the necessity of such a vaccine which causes discomfort for the child without an actual need. But, the fact of the matter is, unless such vaccines are continued, the occurrences of epidemics are inevitable and the world has already experienced several such instances in different parts of the world. But, at times, certain vaccinations are being taken off, due to global reduction in disease incidence and only if it is considered eradicated for certain number of years.

Contraindications and side effects:

Another drawback in giving vaccinations is the side effects and contraindications. Although the side effects are minimal, minor infections and local reactions can be relatively common. In rare instances, severe anaphylaxis could occur and it may lead to fatal outcomes as well.

Effect of the preservatives:

A concern that is shown by many others is the presence of Thimerosal as a preservative in multi dose vaccines, which suppose to contain about 49% Mercury. Mercury can cause toxicity to body organs and it is for this reason that the concerns were mounted. But, it has not proven as toxic when present in the vaccine but, in order to alleviate the fears, the use of Thimerosal has been discontinued in the US.


Although there seems to be a link between vaccinations and autism, its relative rareness makes it to be less significant to stop the whole process of vaccinations.

As described in this article, there can be several reasons which make the decision to give a vaccine something to think about and it will be the right of the parent to make an informed decision as to what is best for your child.
