AEFI: Your Babies Safe from It or Not?
Get your baby some bite-proof cups for babies Malaysia before going to the vaccine center.
What is AEFI?
If observed, the issue of vaccine injection and AEFI is hotly debated and has become the talk of the pro-vaccine and anti-vaccine groups. To learn more about vaccine injections and AEFI, keep reading!
According to the guidelines of vaccine pharmacovigilance in Malaysia (GPFK), AEFI (Adverse Events Following Immunization), or Side Effects following immunization is any effect after receiving a vaccine injection and it is not necessarily closely related to vaccine intake, in fact it can be classified into several causes such as ;
1. Injection Effects
The occurrence of AEFI that occurs is due to fear of or pain after the injection rather than from the injection of the vaccine itself.
For example, at the time of the vaccine injection, if the baby happens to have a cough, cold or mild fever, it is rather than due to the vaccine injection.
3. Operating Errors
Every immunization given is handled, stored and given in an orderly and good manner but errors in the preparation or handling program can cause the occurrence of AEFI but the percentage of this occurrence is so low that the risk cannot be assessed.
4. Vaccine Side Effects
Like other medicines, vaccines also have side effects. However, the percentage of serious AEFI incidence due to vaccines is very minimal.
The cause of the AEFI incident could not be identified.
How is AEFI Assessed?
The majority of AEFI reported were mild, minor incidents and healed in just a few days. The incidence of AEFI can be classified into two classes, namely normal AEFI effects, minor AEFI effects or serious AEFI effects. 97% of the reported AEFI effects are from the normal or minor class and the second class is so minimal that the risk cannot be calculated.
After reviewing the latest epidemiological evidence related to thimerosal and its pharmacokinetic profile, the World Advisory Committee for Vaccine Safety under the World Health Organization has concluded that there is no evidence of toxic effects of mercury on infants, children or adults exposed to thimerosal in vaccines. Furthermore, many studies that have been conducted have found that there is no evidence of nervous system defects or development such as autism due to the use of vaccines containing thimerosal.
What is The Vaccine Contains:
The stabilizer serves to prevent vaccine components from sticking to the walls of the vaccine bottle. It maintains the safety and effectiveness of the vaccine in a wide range of conditions and temperatures. Gelatin and lactose-sorbitol are examples of stabilizers.
Adjuvants are added to the vaccine to increase the immune system’s response to the vaccine. The most commonly used adjuvant is an aluminum salt (known as alum). Aluminum intake from vaccines is lower compared to daily intake from food or medications such as antacids. A review of all available studies related to aluminum -containing diphtheria, tetanus and pertussis vaccines (either separately or in combination) indicates that there is no evidence of aluminum salts in vaccines causing any serious side effects or long -term side effects. Redness and swelling at the injection site are often associated with vaccines that contain aluminum as opposed to vaccines that do not contain aluminum, but these effects are usually mild.
