# VaxEPI: Integrated Vaccine Registration & Vaccination Information (Bangladesh)
|
||
|
||
## 1) What VaxEPI Is (Overview)
|
||
|
||
VaxEPI is Bangladesh DGHS’s public-facing portal (introduced in **2024**) for **integrated vaccine registration** and **vaccination information management**. It covers both **routine EPI** (Expanded Programme on Immunization) and **special campaigns**. VaxEPI is a **single-time registration** system: a child is registered once and remains trackable across programs and facilities. Registration is verified against the **Birth Registration Number (BRN)** to ensure identity integrity and deduplication.
|
||
|
||
VaxEPI is interoperable with the national **Shareable Health Record (SHR)**, so each registered child receives a **Unique Health ID**; all vaccination events appear in the **Health Information Exchange (HIE)** for authorized use. Families receive a **vaccine card with a QR code**; vaccinators record doses and scan the QR to update the central record. Digital **vaccination certificates** are made available via the [VaxEPI portal](https://vaxepi.gov.bd), following EHR-style access patterns. Special campaigns such as **HPV**, **TCV (Typhoid Conjugate Vaccine)**, and **meningitis vaccine for Hajj pilgrims** are also managed through VaxEPI.
|
||
|
||
**Retrieval cues:** “single-time registration”, “BRN verification”, “SHR Unique Health ID”, “QR vaccine card”, “routine EPI + campaigns”, “digital certificate”, “HIE availability”.
|
||
|

|
||
|
||
## 2) Core Objectives
|
||
|
||
* **Universal, deduplicated identity for children** via BRN → SHR → Unique Health ID.
|
||
* **Continuity of care**: one longitudinal vaccination timeline per child across facilities.
|
||
* **Operational efficiency**: unified workflows for routine and campaign activities.
|
||
* **Data quality & exchange**: real-time updates to HIE; fewer missed doses/duplicates.
|
||
* **Citizen convenience**: QR-coded card and downloadable vaccination certificate.
|
||
|

|
||
|
||
## 3) Scope & Program Coverage
|
||
|
||
* **Routine EPI**: BCG, OPV/IPV, Penta, PCV, MR, etc. (country schedule applies).
|
||
* **Special campaigns**: **HPV**, **TCV**, and **meningitis/Hajj** drives, plus other MoHFW/DGHS-approved campaigns.
|
||
* **Population focus**: primarily **children**; program extensions may include adolescents or adults for specific campaigns (e.g., Hajj).
|
||

|
||
|
||
## 4) Identity & Registration Model
|
||
|
||
**Inputs:** Child’s **BRN**, name (Bangla/English), date of birth, sex, guardian details, address/upazila/district, contact number(s).
|
||
**Verification:** Online verification of **BRN** (preventing duplicates).
|
||
**Linkage:** On successful registration, VaxEPI requests/receives a **Unique Health ID** from **SHR**.
|
||
**Artifacts:** **QR-coded vaccine card** (physical and/or digital).
|
||
**Card Use:** QR encodes persistent identifiers (e.g., Health ID and VaxEPI record ID) to enable fast retrieval and updates at point of care.
|
||
|
||

|
||
|
||
## 5) Vaccination Workflow (Facility & Field)
|
||
|
||
1. **Presentation:** Caregiver brings the child and **QR card** to a session (facility or outreach).
|
||
2. **Assessment:** Vaccinator reviews **due/overdue doses** (per age and schedule) in VaxEPI.
|
||
3. **Administration:** Vaccine is given; **dose details** are recorded (vaccine code, dose #, lot/batch, expiry, route, site).
|
||
4. **Update:** Vaccinator **scans the QR**; VaxEPI loads the child record and **posts the dose event**.
|
||
5. **Sync & Exchange:** Event is written to VaxEPI and **propagated to HIE/SHR**.
|
||
6. **Certificate:** A refreshed **digital vaccination certificate** becomes available in the portal.
|
||
|

|
||
|
||
## 6) Citizen Experience
|
||
|
||
* **Discoverability:** Public portal for registration and certificate download.
|
||
* **Proof of vaccination:** **QR-coded card**; digital **certificate** view/print.
|
||
* **Portability:** Records visible across facilities due to SHR Health ID.
|
||
* **Notifications (if enabled):** SMS or portal prompts for upcoming/overdue doses.
|
||
|
||
---
|
||
|
||
## 7) Interoperability & Data Exchange
|
||
|
||
* **SHR (Shareable Health Record):** creation/lookup of **Unique Health ID**.
|
||
* **HIE (Health Information Exchange):** publishes vaccination events for authorized systems.
|
||
* **Standards & semantics:** consistent vaccine codes, dose definitions, and schedule logic to support analytics and exchange.
|
||
* **Result:** Authorized providers and national analytics can **query longitudinal vaccination history** for service continuity and planning.
|
||
|

|
||
|
||
## 8) Special Campaigns (HPV, TCV, Hajj Meningitis)
|
||
|
||
* **Registration:** Uses the **same child record** (no duplicate accounts).
|
||
* **Targeting:** Eligibility computed by **age/sex/risk group** (e.g., adolescent girls for **HPV**, child age bands for **TCV**, **pilgrim status** for Hajj).
|
||
* **Delivery:** VaxEPI supports **bulk session lists**, on-site verification via **QR**, and rapid **dose posting**.
|
||
* **Reporting:** Campaign-specific dashboards can aggregate coverage, dropout, and stock usage.
|
||

|
||
|
||
## 9) Governance, Roles & Access
|
||
|
||
* **DGHS/MIS ownership**; national data stewardship.
|
||
* **Roles:** Registrar (front desk), Vaccinator, Facility Manager, District/Upazila EPI Manager, National Analyst.
|
||
* **Access controls:** Role-based permissions for read/write; certificate access controlled via authenticated portal flow and/or verifiable QR link.
|
||
* **Auditability:** All vaccination events and edits have **provenance** (who/when/where).
|
||
|
||
---
|
||
|
||
## 10) Data Quality & Safety Nets
|
||
|
||
* **Identity deduplication:** BRN check at registration; “possible duplicate” flags.
|
||
* **Schedule validation:** Client-side/server-side checks for **age-appropriate** dosing and minimum intervals.
|
||
* **Lot controls:** Prevent posting events for **expired** lots; require lot/batch.
|
||
* **Correction workflow:** Voiding/mending mis-entries with reason and audit trail.
|
||
|
||

|
||
|
||
## 11) Privacy & Security (High Level)
|
||
|
||
* **PII handling:** Minimal necessary disclosure; **BRN** and **Health ID** protected.
|
||
* **QR contents:** Encodes identifiers or verifiable token, not full PII.
|
||
* **Transport/storage:** Encrypted channels; secure storage per national policy.
|
||
* **Access:** Role-based access; certificate retrieval bound to guardian verification or QR proof.

## 12) Typical User Journeys
|
||
|
||
**A) First-time Registration**
|
||
|
||
1. Guardian opens [VaxEPI](https://vaxepi.gov.bd) → enters **BRN** and child details → system verifies BRN.
|
||
2. VaxEPI fetches/assigns **Unique Health ID (SHR)**.
|
||
3. VaxEPI issues **QR-coded vaccine card**; child appears on due-list.
|
||
|
||
**B) Dose Administration**
|
||
|
||
1. Child presents **QR card** → vaccinator scans → due doses displayed.
|
||
2. Dose given → vaccinator records details → **event saved** → **HIE updated**.
|
||
3. Certificate refreshed → guardian can **download** from portal.
|
||
|
||
**C) Special Campaign (e.g., HPV)**
|
||
|
||
1. Eligibility auto-determined → session roster generated.
|
||
2. On site, **QR scan** retrieves record → dose posted.
|
||
3. Coverage reports update in near-real time.

## 15) One-Paragraph Summary (for fallback retrieval)
|
||
|
||
VaxEPI (launched 2024 by DGHS/MIS) is Bangladesh’s integrated portal for vaccine registration and vaccination information, covering routine EPI and special campaigns (HPV, TCV, Hajj meningitis). Registration is verified by BRN; each child is issued a Unique Health ID from the national Shareable Health Record (SHR). Vaccinators give doses and scan a QR-coded vaccine card to update the record; events sync to the Health Information Exchange (HIE). Families can download an up-to-date digital vaccination certificate from the [VaxEPI portal](https://vaxepi.gov.bd). VaxEPI’s single-time registration, SHR linkage, and QR-based point-of-care updates make it a cornerstone of Bangladesh’s digital health implementation.
