What is in this leaflet
This leaflet answers some of the common questions about INFLUVAC TETRA vaccine. It
does not contain all the available information. It does not take the place of talking
to your doctor, nurse or pharmacist. Please read it carefully and keep it for future
All medicines and vaccines have risks and benefits. Your doctor, nurse or pharmacist
has weighed the possible risks of you having INFLUVAC TETRA against the expected benefits.
Talk to your doctor, nurse or pharmacist if you have any concerns about receiving
What Influvac Tetra is used for
INFLUVAC TETRA is used to prevent certain types of influenza (commonly called flu).
The vaccine works by causing the body to produce its own protection (antibodies) against
four different types of influenza virus.
Each year new types of influenza virus can appear, so every year INFLUVAC TETRA is
changed to contain fragments of the new types of virus. Therefore, influenza vaccination
is recommended every year.
Please note that INFLUVAC TETRA will only protect you against the four types of influenza
virus used to make the vaccine. It will not protect you from influenza caused by other
types of influenza virus or from infections with other agents causing flu-like symptoms
(such as the common cold).
Influenza is an infectious illness. Influenza is spread by small droplets from the
nose, throat or mouth of an infected person. Symptoms of influenza begin 48 hours
after coming into contact with the virus. These consist of chills, fever, generalised
aches and pains, headache and respiratory symptoms (sore throat, runny nose, cough).
The severity and type of symptoms can vary. Most people recover completely within
a week. The risk of serious complications (e.g. pneumonia and death) is greater in
very young, very old and chronically ill persons.
INFLUVAC TETRA can be used in adults and children over the age of 3 years.
Talk to your doctor, nurse or pharmacist if you have any questions.

they are serious; most of the time they are not. Some side effects may need medical

redness, swelling, a hard lump, soreness, bruising or itching around the injection
fever, chills, headache, malaise (generally unwell)
muscle aches and pains
MORE SERIOUS EFFECTS THAT MAY OCCUR RARELY
As with all vaccines given by injection there is a very small risk of serious allergic
reaction. Tell your doctor immediately, or go to Accident and Emergency at your nearest
hospital, if you notice any of the following:
swelling of limbs, face, eyes, inside of nose, mouth or throat
shortness of breath, breathing or swallowing difficulties
hives, itching (especially of the hands or feet), reddening of skin (especially around
the ears), or severe skin reactions
unusual tiredness or weakness that is sudden and severe.
As with all vaccines given by injection there is a very small risk of such reactions.
Allergy to INFLUVAC TETRA is rare. Any such severe reactions will usually occur within
the first few hours of vaccination.
Tell your doctor if you notice anything else that is making you feel unwell.
Other side effects not listed above may occur during or soon after a dose of vaccine.

You may not experience any of them.
