Whether you are preparing for a safari in Zambia or a business trip to Southeast Asia, visiting the McMinns Pharmacy Travel Clinic is the first step toward a safe journey.
However, it is natural to feel a little apprehensive about how your body will react to vaccinations.
The good news? Most side effects are simply a sign that your immune system is busy building a “security team” to protect you from future infections.
Here is our guide on what to expect, how to manage symptoms at home, and the rare signs that mean you should seek professional help.
Common Side Effects: The “Normal” Response
Most travel vaccines – including Hepatitis A, Typhoid, and Rabies – cause mild, temporary reactions that typically resolve within 24 to 48 hours. These are categorized into two types:
Local Reactions (At the injection site)
This is the most common experience, especially with the Typhoid vaccine, which causes soreness in up to 75% of recipients.
- What to expect: Redness, swelling, tenderness, or a small, hard lump where the needle entered.
- How to manage: Apply a cool, damp cloth to the area. Gently moving your arm can also help prevent stiffness.
Systemic Reactions (General body response)
As your immune system activates, you may feel like you have a “mini-flu.”
- What to expect: Low-grade fever (under 38.5°C), fatigue, mild headache, or muscle aches.
- Specifics: The Yellow Fever vaccine often causes mild headache or muscle aches in about 10–30% of people, usually a few days after the injection.
- How to manage: Stay hydrated, rest, and take over-the-counter paracetamol or ibuprofen if needed.
Rare but Serious Side Effects
While extremely rare, more significant reactions can occur. It is important to be aware of them so you can act quickly.
Allergic Reactions (Anaphylaxis)
Severe allergic reactions are exceptionally rare (occurring in roughly 1 per million doses). This is why we ask you to wait in the pharmacy for 15 minutes after your injection – our trained staff are equipped to handle these immediate reactions.
Seek emergency help (Call 999) if you experience:
- Difficulty breathing, wheezing, or a “tight” throat.
- Swelling of the face, lips, or tongue.
- A widespread, itchy rash (hives).
- Dizziness, fainting, or a rapid heartbeat.
Other Red Flags
You should contact your GP or visit A&E if you experience:
- A high fever (above 39°C) that lasts longer than 48 hours.
- Severe or increasing pain and redness at the injection site accompanied by pus.
- Neurological symptoms, such as persistent confusion or unusual numbness.
- For Yellow Fever specifically: Severe abdominal pain or yellowing of the eyes/skin (jaundice) in the weeks following the jab.
Summary: When to Worry?
To help you distinguish between a healthy immune response and a potential issue, use this quick checklist:
| Symptom | Usually Normal If… | Seek Help If… |
| Fever | It is low-grade and lasts <48 hours. | It is >39°C or lasts >2 days. |
| Arm Pain | It feels like a dull ache or bruise. | It is severe, throbbing, or produces pus. |
| Rashes | It is a small red patch near the jab. | It is a “full body” rash or causes swelling. |
| Timeline | Symptoms start 1 – 3 days after the injection. | Symptoms start or worsen after a week. |
