The Omicron cases spike in Indonesia attracted public attention immediately since the cases increased after 110,620,807 Indonesian citizens received their 2nd dose of Covid-19 vaccination. Additionally, public concerns about Omicron began to emerge because news circulated that the Covid-19 vaccines, which are currently available, were not effective against Omicron. So, is it true?

A Clinical Pathology Specialist in Universitas Sebelas Maret (UNS) Hospital, Surakarta, dr. Tonang Dwi Ardyanto, Sp.PK(K), Ph.D., FISQua ., states that the current Covid-19 vaccine only focuses on severe symptoms and death. If we wish to get a Covid-19 vaccine that can prevent infection in the upper respiratory tract, of course, it will take longer. “In countries facing Omicron, for example, the UK, vaccination coverage is already high. When Omicron spread, numerically, it was greater than the number of vaccinated groups. However, if it is proportional or in percentage, it (the Omicron case) is more than the group that has not been vaccinated,” explained dr. Tonang, Monday (12/27/2021).

Considering the rapid increase in Omicron cases in the UK, he explained that the risk of a Covid-19 vaccinated person being hospitalized when infected with Omicron is only 31-45 percent. Meanwhile, for those who have not received their Covid-19 vaccine shots, the risk of undergoing hospitalization in an isolation room when infected with Omicron increases to 50-70 percent.

dr. Tonang added that the Omicron hospitalization percentage for a vaccinated person was lower compared to the Delta variant, which spread in the middle of this year. “Meanwhile, for those recovering from Covid-19 infection but yet to get vaccinated, the risk is 11 percent compared to the Delta variant. This means that it is 4-7 times higher than the vaccinated group against Covid-19,” added dr. Tonang.

If you look at the Covid-19 vaccination coverage in Indonesia, the percentage of complete vaccine injections had reached 40.65 percent. Around 17 percent of the people have just received the first dosage, while around 42.3 percent have not received any dosage of Covid-19 vaccine. Based on this data, dr. Tonang is worried that the un-vaccinated groups against Covid-19 will be more prone to contracting Omicron.

“One point to remember is that the person who gets infected faster is the one with the laxest health protocol, those who do not wear a mask and do not wash their hands regularly. For those who have antibodies, the virus will clear faster. However, those who have yet to develop the antibodies against Covid-19 will need 14 days for the virus to disappear after the initial infection,” said dr. Tonang.

Do we need to use a booster?

Because the currently available Covid-19 vaccines are still not able to prevent people from the new SARS-CoV-2 variant, there has been discoursed for a booster shot(s). On a side note, the booster is different from the third dose, which many people have misinterpreted. Booster is an additional vaccine to ensure that the two doses of the Covid-19 vaccine that have been injected have formed immunity. Meanwhile, the third dose is a vaccine that must be injected and is the central part of the Covid-19 vaccine, like the first and second doses.

Furthermore, dr. Tonang said that the necessity of injecting a booster needs further investigation, considering that the report is still based on laboratory research. “We called it in vitro. Nothing wrong; however, a careful interpretation in the field is needed. The reports (on booster shots) are from countries with 70-80 percent vaccination rate, but in Indonesia, it is only around 40 percent,” added dr. Tonang.

He said, even though someone is at risk of contracting Omicron, it does not mean the effectiveness of the Covid-19 vaccine is lost. dr. Tonang dismissed this assumption and emphasized that the effectiveness of the Covid-19 vaccine was only decreasing. Instead of focusing on discussing the need for boosters, dr. Tonang asked the government to immediately intensify the injection of the second dose of the Covid-19 vaccine. “This is more important, more meaningful, and has a stronger communal effect against whatever Covid-19 variants that still exist and may exist,” he added.

When can a booster be given?

dr. Tonang explained that the World Health Organization (WHO) and the Indonesian Ministry of Health (Kemenkes) agreed that booster injections could be carried out when 50 percent of the population had been vaccinated against Covid-19. “Using an assumption that the proportion of survivors who have not been vaccinated is around 20 percent, most of the survivors have been vaccinated, then with 50 percent vaccination rate along with the 20 percent vaccinated survivor, vaccination rate can reach around 70 percent,” said dr. Tonang.

After reaching this percentage, he said the Ministry of Health could consider delivering a booster, given that the primary Covid-19 vaccination must still be carried out and boosters are addressed for high-risk groups.

“With the average speed of administering vaccines in the last seven days, we can reach 50 percent vaccination rate in about 30-50 days,” he concluded. Humas UNS

The government of Indonesia took a quick response toward the issue by prohibiting foreign nationals (WNA) who visited South Africa, Botswana, Namibia, Zimbabwe, Lesotho, Mozambique, Eswatini, Malawi, Angola, Zambia, and Hongkong in the last 14 days from entering Indonesia. Indonesian people who have a history of visiting the mentioned countries and coming back to Indonesia will undergo 14 days starting from Monday (29/11/2021) 00.01 Jakarta Time.

The spread of the Omicron variant also grasps the attention of Covid-19 Taskforce spokesperson and the Clinal Pathology Specialist Universitas Sebelas Maret (UNS) Surakarta Hospital, Tonang Dwi Ardyanto dr. SpPK, Ph.D.

Although until Tuesday (30/11/2021), the Indonesian government has not confirmed the Omicron variant in Indonesia, it does not mean that the community could be ignorant and disregard the health protocols. With the increase in the reporting over Omicron spread, the community needs to be more careful and apply strict health protocols to prevent the case of Delta variant on July-August in the next Christmas and New Year holidays.

“These days, several countries have reported, including Australia. Those reporting are succeeded in detecting (the new variant). (Countries) that have not reported is not mean that they are free from the new variant. Maybe because they have not yet been successful in detecting it (the new variant),” dr. Tonang said to uns.ac.id on Tuesday (30/11/2021).

Regarding the severity of the new variant, dr. Tonang explained that the information continues to develop according to the spread of this new variant. He asked the community not to be too worried over the severity of the new variant but instead be aware of the issues. He also hoped that the emergency units in hospitals could be more ready in case the infection rate peaked due to the Omicron variant. He does not want Covid-19 patients to get poor service like in the July-August case.

“The malignancy greatly depends on the local condition. The death proportion (CFR) of the Delta variant, for example, is actually low. Although the cases were extreme in several countries, the death percentage was low,” he explained.

dr. Tonang added that Covid-19 handling is focused on the level of spread; therefore, the number of infections could be monitored, infection cases do not soar, health care facilities have the capability to provide services until the infection rate decreases. “What we need to consider is the infection rate. If the cases are soaring, the hospital collapses, beds are not available, (patients) queued in the emergency units, or even forced to stay at home that increases the risk, increases the death rate. It means that we need to be aware of,” dr. Tonang added.

The Wave of Covid-19 Spread

During the 1.5 years of the Covid-19 pandemic globally, Indonesia has experienced two waves that caused a spike in infection rate and death rate. dr. Tonang explained that there are two possible conditions when the wave of Covid-19 occurs. The first condition, the managed ones, when the case is high, but those confirmed with Covid-19 are isolated, and patients could access health care.

“Second (condition), from the beginning of the wave, the spread is uncontrollable, infection rate increases, cases increasing, and, I’m very sorry to say, many died, then after a lot of people got infected, the cases decreasing because the virus couldn’t find a new place to multiply,” dr. Tonang said.

Thus, dr. Tonang asked the government to ensure the community discipline in implementing the health protocols, help in separating the sources of infection through isolation, treat people showing Covid-19 symptoms, and vaccinate people. These efforts also need support by community behavior in wearing a mask, washing hands, and limiting interaction between Indonesia and other countries.

“The two are the government responsibilities because it is impossible for the people to perform it. (The community) could only support. Let us monitor and continue reminding the government if needed so that the government performs their responsibilities,” dr. Tonang stated. Humas UNS
