What you’re probably looking for when you type mibacuna.com

Right now, mibacuna.com doesn’t reliably load (it can return a “502 Bad Gateway” or similar gateway error, depending on where and how you try to access it). When people type it, they’re usually trying to reach a government vaccination portal and they remember the name roughly, not the exact address.

In practice, the well-known “Mi Vacuna” portals that show up in official guidance are:

• Colombia: MiVacuna on the SISPRO domain (used to consult and generate a digital vaccination card/certificate).
• Mexico: “MiVacuna” registration is on mivacuna.salud.gob.mx (used for registration and related processes, and tied to certificate flows).

So if you landed on mibacuna.com, treat it as a likely typo, bookmark confusion, or a domain that’s simply not the official destination. The safest move is to use the official government links referenced by public institutions, not whatever a search ad or forwarded message points you to.

What the Colombia MiVacuna portal is actually for

Colombia’s MiVacuna (SISPRO) is positioned as an official Ministry of Health service to let people consult vaccination history and generate a digital vaccination card, including the yellow fever (fiebre amarilla) record that many travelers need to show. The SISPRO portal’s own description frames it as a Ministry service and references the legal and regulatory basis for issuing the digital vaccination card.

A practical detail that matters more than people expect: the portal’s data coverage is not infinite. Bogotá’s official city portal notes that MiVacuna’s records are available from 2010 onward, and that certificates/cards for yellow fever, COVID-19, and other vaccines are issued based on those records. If you were vaccinated before 2010, the digital record might simply not exist there, and you may need to request proof through in-person channels.

That one line explains a lot of the “it doesn’t show my vaccine” complaints.

Why people need the digital card (and why this got louder again)

Yellow fever documentation is a common reason. If you’re traveling to risk areas or going to destinations that ask for proof of yellow fever vaccination, having a downloadable certificate you can keep on your phone is useful. Bogotá’s guidance explicitly frames it around travel planning and the need to have the document ready.

Even when rules change from place to place, the pattern is stable: airlines, border officials, employers, schools, event organizers—someone eventually asks for proof. A digital certificate reduces the friction, as long as your record is actually in the system.

How the download process works in real life

The steps are fairly basic and feel like most government portals:

1. Accept the terms and conditions for data treatment.
2. Choose your document type (ID type).
3. Enter your identification number (and confirm it).
4. Enter the ID issue date.
5. Complete the captcha.
6. Generate and download the digital vaccination card/certificate.

If you’re doing this for a family member, double-check the ID issue date. That field is a common source of failed lookups because people guess it or type the birth date by habit.

The most common “my vaccine isn’t there” scenarios

You were vaccinated before the portal’s coverage window

If your yellow fever shot was a long time ago, you may have valid protection but no digital trace in this system. Bogotá’s portal states the 2010+ coverage point directly and advises using physical points for older records.

Your dose exists on paper but was never uploaded

This happens when the administering provider hasn’t loaded the vaccination event into the platform yet, or it hasn’t synced. One of the SISPRO portal messages for missing records basically says: check again later or go to your IPS (health provider) to confirm they uploaded the record.

Your information matches, but the system still can’t locate you

Typos, mismatched document types, or an incorrect issue date can break the lookup. Fixing this is boring but effective: re-enter the fields slowly, and make sure the document type matches what was used at vaccination time (people change document types over the years).

Security and safety: don’t hand your ID to random “Mi Vacuna” links

Because these portals ask for identity details, copycat domains and “helpful” third-party pages are a real risk. A good rule is: if it’s not a clear government domain that matches official references, don’t trust it.

A concrete example from the MiVacuna login page text (Colombia) is that it provides an official support contact path for issues with downloading the vaccination card. That kind of support detail is one of the signals you’re on the right service, and it’s safer than following advice from an unknown WhatsApp forward.

Basic hygiene that actually helps:

• Prefer direct government links (SISPRO / ministry / city government pages) over search ads.
• Avoid entering ID details on “mirror” sites, link shorteners, or domains that look slightly off (like mibacuna vs mivacuna).
• If you must search, open the result that is clearly an official institution page and click outward from there.

If the site shows a “502 Bad Gateway” error, what it means and what you can do

A “502 Bad Gateway” is usually not “your phone is broken.” It means a server acting as a gateway/proxy got an invalid response from an upstream server. In plain terms: servers aren’t talking to each other correctly.

For regular users:

• Try again later from a different network (mobile data vs Wi-Fi).
• Refresh once, then stop spam-refreshing (you can make overload worse).
• If it’s a government service during a high-demand period, downtime is not unusual.

For organizations running a site (if you’re reading this as a webmaster, not a citizen):

• Check reverse proxy logs, DNS, upstream health checks, and timeout configuration.
• Look for rate-limiting or WAF rules blocking upstream responses.

If mibacuna.com is the one throwing 502 while the official SISPRO domain works, that’s another signal you should stop trying to use mibacuna.com and go straight to the official source.

Key takeaways

• mibacuna.com is not a reliable or clearly official destination; it may be a typo or an unavailable domain.
• Colombia’s official MiVacuna is associated with SISPRO and is used to generate digital vaccination certificates/cards, including yellow fever.
• If your vaccination was before 2010, the digital record may not appear and you may need in-person verification.
• Missing records often mean the provider hasn’t uploaded the dose yet, or you need to verify with your IPS.
• A 502 error is usually a server-side communication failure, not a problem with your device.

FAQ

Is mibacuna.com an official government vaccination site?

It’s not presented in official references the way the SISPRO MiVacuna domain is, and it may not load consistently. Use links that are clearly published by official institutions instead.

Why doesn’t my yellow fever vaccine appear on MiVacuna?

Common reasons: your vaccine was administered before the system’s coverage window (noted as 2010+ in Bogotá’s guidance), or the provider never uploaded the record.

What information do I need to download the digital vaccination card?

Typically: document type, ID number, ID issue date, and a captcha confirmation, then you generate and download the certificate/card.

What should I do if I get a 502 Bad Gateway error?

Try later, change networks, and avoid entering personal data into alternative “lookalike” domains. A 502 generally indicates a server-to-server failure.

Can I fix a missing record myself?

If the record genuinely isn’t in the database, you usually can’t “self-correct” it online. The practical fix is to contact or visit the vaccinating provider (IPS) or a vaccination point so they can validate and upload/update the record if appropriate.
