No side effects from AstraZeneca COVID-19 vaccine in Indonesia – Commission

JAKARTA: There have been no reports of thrombosis cases with thrombocytopenia syndrome associated with the AstraZeneca COVID-19 vaccine in Indonesia, according to the state commission reviewing the side effects of the vaccine.

The National Commission for the Study and Prevention of Adverse Events Following Immunization, together with the Ministry of Health and the Food and Drug Agency (BPOM), has conducted active and passive monitoring to arrive at this conclusion.

Its chairman, Prof. Hinky Hindra Irawan Satari, said: “The vaccine underwent rigorous assessment through various stages of clinical trials involving millions of participants before approval. Monitoring continues even after distribution.

He made the statement following a media report in the United Kingdom that AstraZeneca had notified that its Covid-19 vaccine might cause a rare side effect known as TTS (thrombosis with thrombocytopenia syndrome).

Indonesia ranks fourth globally in vaccination efforts, with 453 million vaccine doses administered, including 70 million doses of AstraZeneca.

Hinky said active monitoring for potential vaccine-related symptoms, including TTS, was conducted across 14 hospitals in seven regions over a year in line with World Health Organization (WHO) guidelines.

“We observed from March 2021 to July 2022, continuing monitoring to ensure an adequate sample size. Despite the continuation, no cases of TTS associated with the AstraZeneca vaccine were found,” he said.

Following the conclusion of this active monitoring, he said the commission continued passive monitoring and no reports of TTS cases were received.

TTS is a rare condition characterized by blood clots and low platelet counts and has the potential to cause severe symptoms.

“Adverse events following immunization usually occur within four to 42 days after vaccination. Moreover, if TTS cases were detected in Indonesia, they might not be related to the COVID-19 vaccine due to the timing,” he said.
