5 Facts about the Sinovac Vaccine, Can Be Given to Children


The World Health Organization, WHO, recommends people with immune disorders or recipients of vaccines with an inactivated vaccine, such as the Sinovac vaccine, to receive a booster vaccine immediately. Here's everything you need to know about the Sinovac vaccine, compiled by us.

1. Sinovac content

The Sinovac vaccine, also known as CoronaVac, has been granted an emergency use permit.

CoronaVac is a vaccine that contains the inactivated SARS-CoV-2 virus. The injection of the Sinovac vaccine will trigger the immune system to recognize this inactivated virus and produce antibodies to fight it so that COVID-19 infection does not occur.

This vaccine product also contains aluminum hydroxide as an additional ingredient that functions to increase the immune system's response to the vaccine.

2. Efficacy

The Sinovac vaccine was developed by Sinovac Biotech Ltd. This vaccine has passed the third phase of clinical trials conducted in Brazil, Turkey and Indonesia. The third phase of clinical trials in Indonesia showed the vaccine efficacy value, namely the protective effect against COVID-19 of 65.3%.

3. Side effects

The Sinovac vaccine is given in two doses with 0.5 millimeters per dose. Based on the results of clinical trials, it is confirmed that the COVID-19 vaccine is safe and does not cause serious side effects.

If any, some of the side effects that occur after receiving the Sinovac vaccine are:

Pain, redness, or swelling at the injection site


Body feels tired and sleepy

Muscle ache



Throw up

Vaccine recipients are advised to check with a doctor if these side effects do not go away or get worse.

4. Starting to be given to children

The Ministry of Health has started the COVID-19 vaccination for children aged 6-11 years.

The vaccine used for the time being is Sinovac because it has received Emergency Use Authorization (EUA).

5. Suggestions for boosters

Recipients of the vaccine from the killed COVID-19 virus are advised by WHO to immediately get a booster or third dose of vaccine. Suggestions for booster injections are issued so that the body remains protected from the Corona virus due to a decrease in immunity from the vaccine that has been used.

This recommendation was released after the Strategic Advisory Group of Experts (SAGE) for immunization held a meeting on Tuesday last week to evaluate the need for a COVID-19 vaccine booster.

This recommendation was published in response to concerns that the Omicron variant of COVID-19, which is said to be more contagious, would reduce the efficacy of the vaccine.
