Jakarta (ANTARA) - Proper immunization procedures can reduce the risk of adverse events following immunization (AEFI), according to Hindra Irawan Satari, Chief of the National Commission on Adverse Events Following Immunization (Komnas KIPI).

"AEFI is a natural reaction that optimizes biochemical reaction within the body," he explained during a media briefing event related to the 2023 World Immunization Week here on Monday.

Thus, AEFI can arise in the form of seizures, tension, or panting, he stated.

Proper immunization can reduce the sensation of pain during administration and the reaction within the body.

"For intramuscular administration, stretch and gently hold the skin between the thumb and forefinger. Push the entire syringe within a 90-degree angle with a fast and smooth motion," he remarked.

In addition, the syringe withdrawal should be done in a quick and smooth fashion at the same angle as when it was administered into the skin, Satari noted.

Subsequently, immunization-benefiting recipients are required to undergo observation for 30 minutes. If there is a risk of AEFI, then it should be reported and investigated through the KIPI Regional Committee or Komnas KIPI.

"To review the side effects, there should be an independent study outside of the immunization program. The cause and effect evaluation requires an investigation team, which includes other experts," he remarked.

According to Satari, AEFI is divided into two types, with severe level marked by medical incidents after immunization that lead to hospitalization, disability, or death.

Meanwhile, non-severe KIPI is marked by medical incidents after immunization that do not endanger the health of recipients.

The commission reported nine cases of severe AEFI in Indonesia in 2016, with three of them caused by vaccine reactions, while six were coincidental or not vaccine-related.

A similar incident also occurred in 2018, with one caused by a vaccine reaction. In 2019, there were seven coincidental and indeterminate cases.

"The last one occurred in 2022, with one coincidental case," Satari remarked.
