The third dose of COVID-19 vaccine or booster vaccine is considered to be able to increase or restore the effectiveness of the previous COVID-19 vaccine which may weaken over time.

In 2022, the provision of a COVID-19 booster vaccine in Indonesia has begun to be carried out in the community with the target recipients of the vaccine being people over 18 years of age, the elderly, people with comorbid diseases, and people with weak immune systems (immunodeficiency).

When should the third dose of COVID-19 vaccine booster be given?

There are several types of vaccines available to be given as the third dose of the COVID-19 vaccine, namely AstraZeneca, Moderna, Pfizer, Zifivax, and Coronavac vaccines.

Referring to the Circular from the Ministry of He alth issued in 2022, the provision of a booster for COVID-19 vaccine can be done within a minimum of 3 months after the complete dose of COVID-19 vaccination.

There are several things to consider why the COVID-19 booster vaccine was given the time lag.According to some research, most people can experience a decrease in antibody levels to COVID-19 within about 6 months after receiving the full dose of the COVID-19 vaccine.

This is one of the reasons why a COVID-19 booster vaccine needs to be given, especially for groups who are vulnerable to COVID-19, such as he alth workers, the elderly, and people with comorbid diseases.

In fact, pregnant women and breastfeeding mothers are now allowed to get the third dose of COVID-19 vaccine. One of the conditions for giving a COVID-19 booster to pregnant women is that it is done within about 4 months after the second dose of COVID-19 vaccine is given. While for pregnant women, the distance between the second COVID-19 vaccine with a booster remains within 6 months.

Does the COVID-19 Booster Vaccine Type Have to be the Same as the Previous Vaccine Type?

Ideally, the recommended type of COVID-19 booster vaccine is the same vaccine as the previously received vaccine type (homologous).However, if the type of vaccine used for the first time is no longer available, giving booster vaccines from other types of vaccines (heterologous) is still allowed.

For example, for people who previously received the complete Sinovac vaccine, they can get the Moderna vaccine as a booster for the third dose of COVID-19 vaccine.

This is due to the consideration that giving booster vaccines plays an important role in increasing the formation of antibodies to fight the Corona virus, even though the type of vaccine used is not the same as the previous type of vaccine.

In addition, to date, various studies are still being conducted to evaluate the protective effect of different types of booster vaccines to prevent transmission of the Corona virus.

One study in South America showed that giving a third dose of Sinovac vaccine was able to increase its effectiveness by 80% to prevent COVID-19.

Meanwhile, the administration of the third dose of Pfizer and AstraZeneca vaccines showed an increase in effectiveness of 90% and 93%.

How long can the third dose of COVID-19 vaccine booster protect the body?

The body's protective power after receiving 3 times the COVID-19 vaccine can vary from person to person, depending on the type of vaccine obtained, body condition, and the variant of the Corona virus circulating.

To date, studies have shown that the protective effect on a person's body after he receives Pfizer and Moderna booster vaccines can last up to 6–7 months.

The length of protection provided by other booster vaccines is still being studied, but it is estimated that the antibodies formed can also persist for at least 6 months.

Is Periodic Re-administration of COVID-19 Vaccine Required?

Until now, there has been no recommendation regarding the repetition of the COVID-19 vaccine after giving the booster vaccine. If the antibodies after giving the booster vaccine have decreased for some time, the next steps are still being researched, including whether or not the vaccine is needed periodically.

Just like the previous dose, the COVID-19 booster vaccination can also cause side effects that are generally mild and temporary, such as pain at the injection site, fever, muscle aches, headaches, and fatigue.

However, it is important to know that the symptoms that appear after vaccination are a sign that your immune system is forming an immune reaction against the Corona virus.

The third dose of COVID-19 vaccine booster can indeed extend protection against the Corona virus. However, it is not enough to rely solely on vaccines completely. You still have to adhere to strict he alth protocols to minimize the risk of transmitting COVID-19.

If you still have questions about the third dose of COVID-19 vaccine booster or you haven't completed the schedule for giving the first and second doses of vaccine, don't hesitate to consult a doctor, OK.
