Side Effects of AstraZeneca Stronger Than Sinovac?

Of the several types of COVID-19 vaccine used in Indonesia, AstraZeneca and Sinovac vaccines are the two types of vaccines that are widely used due to the availability of doses.

Of the several types of COVID-19 vaccine used in Indonesia, AstraZeneca and Sinovac vaccines are the two types of vaccines that are widely used due to the availability of doses. Indonesia is reported to have secured about 6 million doses of AstraZeneca vaccine and 68 million doses of Sinovac vaccine.

Related to this, in the community there is a perception that the side effects of AstraZeneca vaccine tend to be more severe than Sinovac vaccine. Starting from the story of the experience of people who claim to have undergone COVID-19 vaccination.

Molecular biologist and vaccinologist Ines Atmosukarto explained that the side effects after vaccination can be different for everyone. Some may not feel anything, but there are also those who have a fever to the point of pain regardless of the type of vaccine.

"So his statement can't be big and wide. Because it's back to everyone's immune system," said Ines in her discussion with another molecular biologist, Ahmad Rusdan Utomo, on Pak Ahmad's Youtube channel and was quoted on Wednesday (19/5/2021).

However, Ines admitted that he had heard the news about the side effects of the AstraZeneca vaccine being more 'strong'. One theory that may explain why there are platform differences or different development technologies between the COVID-19 AstraZeneca vaccine and Sinovac.

Most likely because the vaccine actually consists of a virus that is still alive but weakened. So what is the name of the reaction is much more complex.

"Our body's reaction. It's a sign that the immune system is working to recognize this adenovirus carrier as something foreign and then an immune response arises," he continued.

The AstraZeneca vaccine is known to be developed with the adenovirus platform. Researchers modified a harmless virus from chimpanzees to carry SARS-CoV-2 virus material and trigger an immune response.

While the Sinovac vaccine was developed with an inactivated platform. Intact SARS-CoV-2 virus that has been killed is used in the vaccine to trigger an immune response.
