These side effects can affect between one and 10 in every people being immunised, depending on the vaccine. They are mostly mild and usually last one to two days. If a reaction following immunisation is unexpected, persistent or severe, or if you are worried, see your GP doctor. It is also important to seek medical advice if you or someone in your care is unwell, as this may be due to an illness rather than because of the immunisation.
You can discuss with your immunisation provider how to report adverse events in other states or territories. There is a very small chance of experiencing a serious reaction after immunisation. A serious reaction is an unwanted and unexpected symptom or sign associated with the immunisation. This is why you are advised to stay at the clinic or medical surgery for at least 15 minutes after receiving a vaccine in case further treatment is required. Examples of uncommon or rare reactions are:.
If any other reactions are severe and persistent, or if you are worried, contact your GP doctor immediately or dial Millions of people — many of them babies and young children — are immunised every year, with no side effects. You can be sure the immunisations used in Australia are safe. Did you know it can take up to 10 years for a vaccine to be approved in Australia? Every vaccine is manufactured and tested according to strict safety guidelines. The Therapeutic Goods Administration TGA conducts detailed surveillance to make sure vaccines stay safe and effective.
Think of it this way — a vaccine is a medicine that we use to stop ourselves and those in our care from getting sick. We are much less likely to get an illness if we are immunised. Immunisations are medicine. Like any medicine, they can cause mild side effects. In rare cases, they can cause more serious side effects, but the chance of an immunisation seriously harming us is rare.
Deciding not to be immunised puts you, loved ones and the community at risk of unnecessarily catching an infectious disease that can be very serious and even deadly. If you have questions , a good first step is to talk to your GP doctor. If you have young children, maternal and child health nurses , or paediatricians can also help.
They can explain how vaccines work, discuss the benefits of immunisation and the risks of disease, and outline your options. Before you agree to any vaccines, your immunisation provider has to give you all the information you need to make an informed decision. Your consent must be voluntary, without any pressure, coercion or manipulation.
And you do not have to give your consent until your immunisation provider has explained the risks and benefits. A significant increase in the rate of fever in vaccinees, compared with nonvaccinees, was present only on day 2 after immunization, and the increase was of low grade mean temperature, There are, therefore, a multitude of reasons precluding definitive conclusions regarding the frequency and significance of fever as an AEFI, including limited knowledge of the variable background rates of fever in various age groups and a lack of sufficient comparisons of fever rates in vaccinated and unvaccinated populations in a controlled setting.
Defining the true importance of fever as an AEFI has been hindered by the limited comparability of data derived from different vaccine safety surveillance systems and by the use in different vaccine safety trials of different temperature limits, diverse sites for measuring temperature, and a wide variety of devices for identifying fever. The lack of a standardized definition is not unique to the evaluation of fever; it extends to virtually all other AEFIs as well.
To overcome this difficulty, an international task force was recently assembled, consisting of professionals from patient care, public health, and scientific, pharmaceutical, regulatory, and professional organizations in both developed and developing countries [ 59 ]. This group—the Brighton Collaboration, named after the town in Great Britain where it was conceptualized in —has as its goal the development of globally accepted standardized case definitions and guidelines for data collection, analysis, and presentation of AEFIs.
Towards that end, a working group was formed within the Brighton Collaboration in to standardize the definition of fever as an AEFI. Any meaningful comparison of fever rates using such disparate criteria and methodology—even rates attributable to the same vaccine evaluated at different times at different study sites—would be difficult at best and, in most cases, impossible.
Clearly, standardization of the definition and method of diagnosis and analysis of fever in surveillance systems and vaccine trials would substantially improve our understanding of this common event.
Although it was recognized that this value is, to some extent, arbitrary, it is based on a conservative interpretation of definitions proposed and used over the years by clinicians, investigators, and the public at large. Because it would be practically and scientifically inappropriate to impose a global standard for devices and route of measurement, the working group also developed a set of guidelines for the standardized collection, analysis, and presentation of data on fever as an AEFI to enable the highest degree of comparability.
Despite the wide leniency in choice of measurement site and device, establishing consistency within and between trials was deemed essential for comparability of data. The working group document was made available on the Internet for public comment for 6 months and appears to have garnered wide acceptance. It is hoped that this definition document, together with others currently under evaluation by the Brighton Collaboration, will facilitate standardized recording and presentation of AEFI data acceptable for global use.
Selected guidelines for temperature measurement for standardized understanding of fever data in immunization safety. In conclusion, although many aspects of the societal, medical, economic, and epidemiologic meaning of fever as an AEFI are still elusive, it is a common, generally benign, clinical sign.
In addition, a globally standardized assessment and reporting of the event, as proposed by the Brighton Collaboration, is a step toward a more scientifically rigorous understanding of its incidence and true significance.
