When something doesn’t feel right, a lot of South Africans don’t phone a doctor first. They open TikTok and search.
That’s a big shift. 29.1 million South African adults can now be reached on TikTok, up a third in a single year (DataReportal, Digital 2026). Health questions are part of that scroll. So are myths, miracle cures and half-truths, travelling at exactly the same speed as good advice.
SPACE was one of the partners behind Influencer Marketing for Public Health, a practical guide built on real South African and Eswatini vaccine campaigns (read the guide). Here are five lessons from it that every health brand should know before working with creators.
1. Credible beats famous
In health, the most powerful creator isn’t always the one with the most followers. It’s the one the audience already trusts on the topic.
The guide’s Eswatini campaign showed this clearly. Medical and religious voices did the trust-building by answering people’s real questions. Comedians then drove the most engagement and clicks. The lesson: don’t lean on one type of creator, and never rely on celebrity alone. Put a credible messenger at the centre and build around them.
2. Match the creator to the goal
Follower count is a tool, not a trophy. Choose the tier for the job you need done.
| Tier | Followers | Best for |
|---|---|---|
| Mega | 1M+ | Mass reach and awareness |
| Macro | 50K to 1M | Reach with credibility on a topic |
| Micro | 10K to 50K | Engagement and shifting attitudes |
| Nano | Under 10K | Hyper-local communities and social norms |
A national awareness push and a campaign to change minds in one township need very different line-ups. Most strong campaigns mix tiers.
3. Brief like a partner, not a client
Audiences can smell a script from a mile away. The guide is clear that creators must speak in their own voice, not as a brand’s mouthpiece.
That means proper briefing: workshops and real conversations, not a PDF dropped in an inbox. Give creators credible source material, build the message with them, and test it before it goes live. If a creator can’t stand behind the facts, they’re the wrong creator.
The same goes for money. Big endorsement fees can actually hurt credibility, so the deal should feel less like a paid ad and more like a shared mission.
4. Go beyond the creator’s following, and measure properly
A creator’s audience is a great starting point, but it shouldn’t be the whole plan. The guide recommends a full media mix: paid media behind the best content, your own channels, earned press, and real-world conversations, like those that happen in a clinic.
Measurement deserves the same rigour. Views are nice. Changed behaviour is the goal. The guide advises combining several data sources, such as media monitoring, before-and-after surveys and interviews, so you can see whether attitudes and actions actually moved.
5. Plan for the platform rules
Health content gets extra scrutiny online, and rightly so. In the guide’s national TikTok and radio campaign, 14 vetted creators and three radio DJs reached more than 12 million people, with 10 million TikTok views. Getting there took paperwork: the team needed official letters from the donor and local government to prove the campaign was legitimate.
Two practical takeaways. Build approval time into your launch plan. And agree data access upfront, because platforms don’t always share the back-end numbers you’ll want for reporting.
What this means for your brand
If you’re in health, pharma, insurance or wellness, TikTok isn’t optional any more. But showing up isn’t enough. You need a voice people believe.
That’s why we work with creators like Dr Randall Ortel, South Africa’s TikTok Doctor. He’s a family medicine specialist who grew up in Manenberg, and his community of 87,000+ followers trusts him for straight medical facts in a language they understand. Every brief he takes on goes through medical ethics and regulatory checks before it goes live.
Credible voice. Native content. Measured results. That’s how health brands win on TikTok.
