April 24 to 30 is World Immunization Week, and while that may not sound like the most exciting thing on your calendar, hear us out — this week is actually a big deal. It’s about celebrating the science that’s kept us healthy, alive and not living in a constant episode of Oregon Trail (you did not die of dysentery, thanks to vaccines).

World Immunization Week is a chance to actually do something—no lab coat required, because somehow, in the year 2025, basic science still needs a PR team. That’s why World Immunization Week exists, to remind us all that vaccines work, and misinformation can kindly see itself out.

Here’s how to celebrate like a professional:

1. Check Your Vax Status

Before you start championing vaccines, make sure you’re up to date yourself. Adult vaccines like tetanus, shingles, flu, HPV and, yes, COVID boosters are still important. Ask your doctor or pop into a pharmacy and see if you’re due for anything.

2. Help Someone Else Get Theirs

Got a friend, parent or neighbor who’s been putting off their shots? Offer to help them book an appointment or drive them there. You’d be surprised how far a little encouragement (and maybe a post-shot snack bribe) can go.

3. Post with Purpose

Use your social media powers for good. Share your vaccine story, a cool fact or even a throwback photo of you as a baby post-immunization (those chubby-arm Band-Aids were iconic). Use the hashtags like #WorldImmunizationWeek and #VaccinesWork. It’s about awareness.

4. Support Organizations Doing the Work

There are plenty of global and local orgs working to make vaccines accessible everywhere—Gavi, UNICEF and WHO, just to name a few. Donate, amplify their message or read up on how vaccine equity works. Knowledge = power.

5. Talk About It 

No need to preach—just have real conversations. If someone brings up vaccines, share your experience. Ask questions. Continue the dialogue.

Why It Matters

Immunization has saved millions of lives—and continues to do so every day. It’s not just about COVID; it’s about measles, polio, HPV, pneumonia and so many preventable threats that are still very real in many parts of the world. It’s worth talking about.

World Immunization Week doesn’t require a parade or a giant awareness banner (unless you’re into that). It just needs a little attention, a little action and maybe a celebratory cupcake or two. Because protecting yourself and others? That’s always worth celebrating.

💉 One week. One world. Countless lives saved.
