Good day everyone,
🩺 Before You Give or received a Tetanus Injection — Know This
A few days ago, I witnessed a scenario that made me realize how important it is to understand the difference between TT, TD, and ATS before giving or accepting any tetanus injection.
Someone had an injury and was rushed to a nearby drug outlet for first aid. An auxiliary nurse immediately prescribed a set of injections — one of them was Tetanus Toxoid (TT). I asked her, “Why TT?” She replied, “To prevent tetanus.”
I paused and smiled. But instead of arguing, I went directly to the injured person and asked a few questions about her medical history. That’s how I found out she had just received a child immunization recently — meaning she most likely already got a TT shot as part of routine maternal immunization.
At that point, I advised against giving another TT injection.
This situation made me realize how many people, even some health workers, don't fully understand when and which type of tetanus protection to use. So here’s a breakdown:
🧬 Know the Difference: TT, TD, and ATS
1. Tetanus Toxoid (TT)
What it is: A vaccine that trains the body to build long-term protection against tetanus.
Where it's found: Commonly available in pharmacies and clinics.
When to use: For routine immunization or as a booster, not suitable for immediate/emergency use.
Note: It takes days to weeks to build immunity.
2. Tetanus Diphtheria (TD)
What it is: A combined vaccine for tetanus and diphtheria, used in adults and mothers.
Where it's found: Usually in healthcare centers or immunization clinics.
When to use: For long-term protection, especially in women of childbearing age.
Note: Diphtheria can also infect wounds, so this vaccine serves a dual protective role.
3. Anti-Tetanus Serum (ATS)
What it is: A serum that provides immediate, short-term protection through ready-made antibodies
When to use: In emergencies, especially for unimmunized or partially immunized people with a tetanus-prone
