In Indonesia, the provision of the third dose of COVID-19 vaccine booster has started to be implemented for people over the age of 18 and have received the second dose of COVID-19 vaccination at least 3 months earlier.

Meanwhile, the administration of the 4th dose of the COVID-19 vaccine has been carried out in other countries, such as Israel. In this 4th dose, the administration of the vaccine is focused on more vulnerable groups, such as the elderly, people with weak immune systems, and he alth workers.

What Are the Facts About the 4th Dose of the COVID-19 Vaccine?

Studies on administering the 4th dose of COVID-19 vaccine in Israel show that people who received all four doses of the COVID-19 vaccine had a lower risk of infection and severe symptoms than people who did not receive the 4th dose of vaccine.

However, the study did not explain the similarity of risk factors between groups of people who received and did not receive the 4th dose of the COVID-19 vaccine. In fact, certain risk factors, such as comorbid diseases, can be aggravating the symptoms of COVID-19.

A recent study also states that the 4th dose of Pfizer's COVID-19 vaccine given 4 months after the third dose is more effective in several ways, such as:

  • Reducing Corona virus infection
  • Reducing the occurrence of severe COVID-19 symptoms
  • Reducing hospitalization
  • Reducing the number of deaths due to COVID-19

Unfortunately, this study does not explain the possibility of factors other than COVID-19 that could have been the cause of death for the group of people in the study who did not receive the 4th dose of the COVID-19 vaccine.

Besides, this study is too quick to conclude that the 4th dose of COVID-19 vaccine can immediately reduce infection cases after a few days of vaccination. In fact, the body actually takes longer to increase immunity and protect the body from infection.

The United States Food and Drug Administration, the Food & Drug Administration (FDA), has approved the 4th dose of Moderna and Pfizer COVID-19 vaccines as emergency administration for people over 50 years of age.

However, there are not many studies with strong evidence to support giving the 4th dose of the COVID-19 vaccine to he althy people in certain age groups, such as adolescents, adults, and the elderly.

Is the 4th Dose of COVID-19 Vaccine Required?

Until now, there is not much strong evidence regarding the need or not to give the 4th dose of the COVID-19 vaccine. More extensive and in-depth research is still being carried out to ensure the safety of the fourth dose of vaccine.

In addition, supporting data is still needed to ensure the benefits of this fourth dose, for example to reduce the risk of severe symptoms or death from COVID-19.

Further research is also needed to determine whether this fourth dose should be given to the entire community or only certain groups who are more susceptible to COVID-19 infection.

While waiting for recommendations regarding the 4th dose of the COVID-19 vaccine, it's a good idea to fulfill the recommendations regarding the existing COVID-19 vaccination first.If you have received all three doses of the COVID-19 vaccine, don't forget to follow the he alth protocols to minimize the risk of transmitting COVID-19.

If you have any questions about the 4th dose of COVID-19 vaccine or you want to complete the COVID-19 vaccination schedule from the first to the third dose, don't hesitate to consult your doctor.
