BIAS 2026: Indonesia Rallies Students for Immunization Through a Profile Picture
School Immunization Month reaches Indonesia's elementary schools twice a year, and this round arrived with a first-person line people could put their own face behind
On August 2, a community health center or puskesmas in Grogol, Cilegon posted an announcement, and it is a cheerful piece of work. A cartoon megaphone in the corner calls out Ayo Sukseskan!, "Let's make it a success!" BIAS is set in multicolored capitals against a bright sky. Posters in this key go up across district health offices and puskesmas channels every August. Bulan Imunisasi Anak Sekolah (BIAS), School Immunization Month, runs in two passes each year. It is free, conducted at the school itself, through every elementary school and madrasah in the country. The August round covers measles-rubella for grade 1 and HPV for grade 5, with the HPV program widened in 2026 to include boys in DKI Jakarta, Yogyakarta, and Bali. What about the rest of the provinces? "We will start this year for three provinces," explained Indri Yogyaswari, the ministry's director of immunization, "before our nationwide plan."
Three days before the August round opened, on July 29, a work team inside that same immunization directorate published a Twibbonize page for it. The creator credit reads Tim kerja 1 bayi & baduta, "Team 1, Infants and Under-Twos". The line the campaign hands people is BIAS Tuntas, Anak Sekolah Sehat dan Terlindungi, "Completing BIAS, School children get healthy and protected." This slogan calls for a complete vaccination for students in Elementary school. And this is congruent with a small detail from the Puskesmas Grogol poster. Past the students and the schedule table, a small drawing of a vaccine vial is seen above the closing line. The label on the vial reads Imunisasi Aman & Halal. Safe and halal.
Indonesia's Ministry of Health (Kemenkes) concluded in 2023 that the primary barrier to reaching national immunization targets is low public acceptance rather than any shortage of vaccines or health workers. Its own health promotion writing is unusually direct about why: people more readily believe emotional information wrapped in frightening narratives than formal scientific data. "Halal" status sits on that list of doubts alongside claims about autism and tracking chips, and it persists despite a supportive ruling, or fatwa, from the Indonesian Ulama Council. The slogan, then, functions to reach people's hearts first before any scientific data can fight the baseless claims.
The stakes behind that are documented. By October 2025, four provinces had reached complete immunization coverage while 13 had missed the 90 percent threshold three years running. Measles and rubella outbreaks reached 31 provinces and 181 districts, with more than 2,000 cases throughout the year. In Sumenep, Madura, 22 people died, most of them children under five, and 21 of the 22 had never received the measles-rubella vaccine. WHO's 2023 count placed Indonesia sixth in the world for children who have received no immunization at all, at 1,356,367.
Now in 2026, the focus hasn't shifted from combatting the doubters, but this year the move is to plant the notion that immunization is fun and necessary. The official Instagram account of the health ministry @kemenkes_ri saw an opportunity in the program's abbreviation.

In a recent post, the ministry compares BIAS with a K-Pop bias, a term that fans of the music genre would use to describe their most favorite member in a group. And they feature the South Korean girl group NewJeans. The post reaches for attention on those terms, and their socialization efforts are brought to the Twibbonize campaign as well.
The campaign page had drawn 1,984 supporters by publication. The gallery fills with individual Indonesian names arriving at intervals of hours and days. But instead of a spike in engagements illustrated in the Instagram post, the campaign moves steadily through an organizational structure, climbing in steps rather than spiking, one step for each health office and puskesmas that picks it up.

Some clinics even announced it as a form of a competition.

This is an Awareness campaign by the book, an annual observance published by an institution, but in a country where the obstacle is trust rather than information, it also works as a pledge, one that makes the success of BIAS a target for everyone to reach together. The joke Instagram post works to frame immunization as an ordinary thing to do, just like having an idol. The Twibbon supports this by turning participation in immunization into a moment students can actually showcase, either through a profile picture or social media post. Both efforts work hand in hand to spark an understanding that BIAS is necessary and can be fun.
Indonesia has the hard parts covered. Cold chains, puskesmas, trained nurses, a two-round national schedule, and cheerful artwork printed down to the sub-district. What a poster cannot do, however well made, is vouch for itself. A neighbor can. That is what the ministry put on offer three days early, and every face that takes it up is evidence a hesitant parent can actually weigh.
