By vaccinating more socially mobile and economically active groups first, Indonesian government officials hope the government can quickly reach herd immunity.

JAKARTA 鈥 As Indonesia prepares to begin mass inoculations against COVID-19, its plan to prioritize working-age adults over the elderly, aiming to reach herd immunity fast and revive the economy, will be closely watched by other countries.

Several countries such as the United States and Britain that have already begun vaccinations are giving priority to elderly people who are more vulnerable to the respiratory disease.

The following are experts鈥 views on merits and risks of the Indonesian approach, under which working-age adults will be vaccinated after frontline health workers and public servants.

WHY 18鈥59 YEAR-OLDS FIRST?
Indonesia, which plans to begin mass inoculations with a vaccine developed by China鈥檚 Sinovac Biotech, says it does not have enough data yet of the vaccine鈥檚 efficacy on elderly people, as clinical trials underway in the country involves people aged 18鈥59.

鈥淲e鈥檙e not bucking the trend,鈥 said Siti Nadia Tarmizi, a senior health ministry official, adding authorities would await recommendations from the country鈥檚 drug regulators to decide on vaccination plans for the elderly.

While Britain and the United States began immunizations with a shot developed by Pfizer Inc. and its partner BioNTech that showed it works well in people of all ages, Indonesia has initial access only to the Sinovac vaccine.

The Southeast Asian country has a deal to receive 125.5 million doses of Sinovac鈥檚 CoronaVac shot, and a first batch of 3 million doses are already in the country.

Shipments of the Pfizer vaccine to the country are expected to begin from the third quarter, while a vaccine developed by AstraZeneca and Oxford University will start being distributed in the second quarter.

鈥淚 don鈥檛 think anybody can get too dogmatic about what is the right approach,鈥 said Peter Collignon, professor of infectious diseases at Australian National University, adding that Indonesia鈥檚 strategy could slow the spread of the disease, although it may not affect mortality rates.

鈥淚ndonesia doing it different to the US and Europe is of value, because it will tell us (whether) you鈥檒l see a more dramatic effect in Indonesia than Europe or US because of the strategy they鈥檙e doing, but I don鈥檛 think anybody knows the answer.鈥

Professor Dale Fisher from the Yong Loo Lin School of Medicine at the National University of Singapore said he understood the rationale of Indonesia鈥檚 approach.

鈥淵ounger working adults are generally more active, more social and travel more so this strategy should decrease community transmission faster than vaccinating older individuals,鈥 he said.

鈥淥f course older people are more at risk of severe disease and death so vaccinating those has an alternative rationale. I see merit in both strategies.鈥

WILL IT HELP ACHIEVE HERD IMMUNITY QUICKLY?
By vaccinating more socially mobile and economically active groups first, Indonesian government officials hope the government can quickly reach herd immunity.

Budi Gunadi Sadikin, Indonesia鈥檚 health minister, said the country needs to vaccinate 181.5 million people, or roughly 67% of its population, to reach herd immunity, and requires almost 427 million doses of vaccines, assuming a double-dose regimen and a 15% wastage rate.

Some experts are skeptical about reaching herd immunity, as more research needs to be done to ascertain whether or not vaccinated people can transmit the virus.

鈥淭here could be the risk of people still capable of spreading the disease to the others,鈥 said Hasbullah Thabrany, chief of the Indonesian Health Economic Association.

WILL IT HELP ECONOMIC RECOVERY?
Economists have argued a successful vaccination program covering around 100 million people will help jumpstart the economy, as they are more likely to resume economic activity such as spending and production.

Faisal Rachman, an economist with Bank Mandiri, said that the 18鈥59 age group has consumption needs that are higher than other groups.

鈥淭hey could jack up the economic recovery faster because household consumption contributes more than 50% to Indonesia鈥檚 economy,鈥 he said, warning that rising COVID-19 cases in the country could also risk lowering people鈥檚 confidence.

The pandemic pushed Indonesia, Southeast Asia鈥檚 largest economy, into its first recession in more than two decades last year, with the government estimating a contraction of as much as 2.2%. 鈥 Stanley Widianto and Tabita Diela/Reuters
