a. Summary of the safety profile
In clinical studies, the most common events occurring after vaccine administration were local injection site reactions (pain, erythema, induration and oedema) reported by 65 to 80% of subjects in each trial. These usually had their onset within the 48 hours following vaccination and persisted for 1 to 2 days. These reactions are sometimes accompanied by injection site nodules.
b. Tabulated list of adverse reactions
The adverse reactions are ranked under headings of frequency using the following convention:
Very common: | (≥ 1/10) |
Common: | (≥ 1/100 to <1/10) |
Uncommon: | (≥ 1/1,000 to <1/100) |
Rare: | (≥ 1/10,000 to <1/1,000) |
Very rare: | (<1/10,000) |
Not known (cannot be estimated from the available data
Based on spontaneous reporting, these adverse events have been very rarely reported following commercial use of Revaxis. Because events are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to vaccine exposure.

General disorders and administration site conditions
• Very common:
- Local reactions (injection site pain, injection site erythema, injection site induration, injection site oedema and injection site nodule)
• Common:
- Pyrexia
• Uncommon:
- Malaise
• Not known
- Large injection site reaction (>50 mm), including extensive limb swelling from the injection site beyond one or both joints have been reported. These reactions start within 24-72 hours after vaccination, may be associated with erythema, warmth, tenderness or pain at the injection site and resolve spontaneously within 3-5 days.
Pallor, asthenia, usually occurring and resolving within a few days, chills, influenza-like symptoms, mostly the same day as the vaccination
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
