Medical Safety Disclaimer: The information on this page is for educational and informational purposes only and does not constitute medical advice, diagnosis, or treatment. If you or someone you know is experiencing severe or life-threatening symptoms after receiving a vaccine or medication, seek immediate emergency medical care. Never stop, start, or alter any prescribed medication or vaccination schedule without direct guidance from a qualified healthcare professional.
An adverse event following immunisation (AEFI) refers to any untoward medical occurrence that happens after a vaccination. It is important to note that an adverse event is defined chronologically—it occurs after immunisation, but it does not necessarily have a proven causal relationship with the vaccine itself. In South Africa, monitoring these events is a critical component of national pharmacovigilance, managed by the South African Health Products Regulatory Authority (SAHPRA) in collaboration with the National Department of Health (NDoH).
Whether you experienced a mild local reaction or suspect a more unusual response, reporting these occurrences helps public health authorities monitor vaccine safety across the country. You can learn more about how national monitoring works through our SAHPRA / South African Reporting hub and consult our broader related parent guide on patient health rights.
Quick answer: when and how to report a suspected side effect
If you experience an unexpected symptom, discomfort, or health problem after receiving a vaccine in South Africa, you have the right and ability to report it. You should report any side effect that is severe, persistent, unexpected, or concerning to you—even if you are not entirely sure that the vaccine caused it.
Reports can be submitted through several official pathways:
- The SAHPRA Med Safety Mobile App (available on iOS and Android).
- Direct consultation with a healthcare provider (clinic nurse, GP, or pharmacist), who will submit an official Adverse Event Following Immunisation (AEFI) form on your behalf.
- The SAHPRA e-Reporting Portal or paper-based Adverse Drug Reaction (ADR) form.
What information to record
To ensure your report is actionable, record the exact brand or name of the vaccine, the date and site of administration (e.g., left arm at a local clinic), the lot/batch number (found on your vaccination card), the exact time symptoms started, and a brief description of what you experienced.
Where reporting fits into medicine safety
Reporting feeds directly into national and global pharmacovigilance databases. It allows safety scientists to detect rare signals, monitor batch quality, update product information, and ensure that health products used across South Africa remain safe and effective for the population.
Who can report a side effect or adverse drug reaction?
In South Africa, vaccine safety surveillance is an open and inclusive system. Anyone can report a suspected side effect or adverse reaction.
- Patients and Consumers: You do not need to be a medical expert to report what you felt after a vaccination. Patients, parents, and caregivers can submit reports directly.
- Healthcare Professionals: Doctors, nurses, pharmacists, and community health workers are required by professional guidelines to report suspected adverse events.
- Immunisation Site Staff: Facilities administering vaccines maintain dedicated logs and reporting pathways for any immediate or reported post-vaccination events.
What information to record
When a patient or caregiver submits a report, key contact details should be included so that health authorities or facility staff can follow up if additional clinical context is required. This includes basic demographic details, age, gender, and contact information.
Where reporting fits into medicine safety
By allowing direct consumer reporting alongside professional reporting, SAHPRA ensures that real-world experiences from every community in South Africa are captured, reducing under-reporting and enhancing the speed at which potential safety signals are identified.
What information should you collect before reporting?
Before initiating a report—whether online or through a clinician—having your details organized will make the process faster and more effective.
| Category | Recommended Details to Gather |
| Patient Information | Initials, age, sex, province, and general health background. |
| Vaccine Details | Vaccine trade name, manufacturer, dose number (e.g., 1st or booster), batch/lot number, and vaccination date. |
| Reaction Details | Date and exact time symptoms began, duration, severity, and full description of the event. |
| Treatment & Outcome | Any medical attention received, medications taken to relieve symptoms, and whether the event has resolved. |
What information to record
Keep your physical vaccination card or digital certificate nearby while filling out the reporting form. The batch or lot number printed on your card is particularly valuable because it enables regulators to track specific manufacturing lots.
Where reporting fits into medicine safety
Detailed, accurate data collection prevents ambiguous reports. When SAHPRA receives precise batch numbers and symptom timelines, epidemiological teams can quickly determine whether an event is isolated or part of a broader pattern.
How to report through SAHPRA, Med Safety or the ADR form
South Africa provides multiple user-friendly channels for reporting adverse events following immunisation:
1. The Med Safety App
The Med Safety App is a free mobile application created to simplify side effect reporting in South Africa.
- Download the app from the Apple App Store or Google Play Store.
- Select South Africa / SAHPRA as your location.
- Create a profile or proceed as a guest.
- Select Report a Side Effect and follow the step-by-step prompts.
2. Reporting via Healthcare Facilities
If you visit a public clinic, day hospital, GP, or pharmacy regarding a side effect, inform the healthcare professional that your symptoms started after vaccination. They will complete a standardized AEFI reporting form and forward it to the district communicable disease coordinator and SAHPRA.
3. Electronic Web Portals & ADR Forms
Healthcare providers and members of the public can also access the electronic reporting portal on the official SAHPRA website or download the paper-based Adverse Drug Reaction (ADR) / AEFI form to submit via email.
What information to record
Whichever tool you choose, ensure you note any concomitant medications (other prescription drugs, over-the-counter remedies, or traditional herbal medicines) you were taking at the time of vaccination.
Where reporting fits into medicine safety
These channels converge into SAHPRA’s National Pharmacovigilance Centre. From there, anonymised data is shared with global health bodies, including the World Health Organization (WHO) Uppsala Monitoring Centre, ensuring South Africa contributes to international medicine safety monitoring.
What counts as a serious or unexpected side effect?
Most side effects following immunisation are mild, expected, and short-lived. Common expected reactions include mild fever, fatigue, headache, muscle aches, or soreness at the injection site. However, it is essential to distinguish between expected post-vaccine responses and serious red-flag events.
Red-flag symptoms
Seek immediate emergency medical attention if you or someone else experiences any of the following symptoms after vaccination:
- Difficulty breathing, wheezing, or severe shortness of breath
- Swelling of the face, lips, tongue, or throat
- Chest pain, pressure, or an irregular/racing heartbeat
- Sudden dizziness, weakness, severe lightheadedness, or fainting
- Seizures or convulsions
- Severe, widespread rash, hives, or skin peeling
- Unusual or severe bleeding or unexplained bruising
- Severe, persistent headache accompanied by vision changes or neurological symptoms
- Rapidly worsening symptoms of any kind
When to contact a doctor, pharmacist, or emergency service
- For Red Flags: Go to the nearest hospital emergency room immediately or call emergency services (e.g., 112 or 10177 in South Africa).
- For Moderate/Persistent Symptoms: If symptoms persist beyond 2 to 3 days, worsen gradually, or cause significant distress, contact your local general practitioner or clinic sister for a formal clinical review.
- For General Advice: You can speak to a local pharmacist for guidance on over-the-counter symptomatic relief (such as paracetamol for a mild fever), provided severe symptoms have been ruled out.
What happens after a report is submitted?
Submitting a report triggers a structured review process designed to safeguard public health:
- Receipt & Triaging: SAHPRA and national pharmacovigilance officers receive and log the report into the national database.
- Causality Assessment: For serious events, medical experts evaluate the clinical evidence, medical history, timing, and biological plausibility to assess whether a causal connection to the vaccine exists.
- Safety Monitoring: Individual reports are aggregated with thousands of others to detect potential patterns or rare adverse reactions across different demographics.
- Regulatory Action: If a true safety issue is identified, SAHPRA may issue public safety alerts, update product leaflets, adjust administration guidelines, or temporarily pause specific batches.
What information to record
After submitting a report via the Med Safety App or web portal, save your report reference number. If your symptoms change or if you receive new diagnostic results from a doctor, you can update your existing record.
Where reporting fits into medicine safety
Pharmacovigilance is an ongoing, continuous process. Safety monitoring does not end when a vaccine is approved; reporting ensures continuous oversight throughout the entire lifespan of a health product in South Africa.
