Influvac Tetra – Influenza Vaccine – Uses, Side Effects, Dosage & Price in Pakistan

Influvac Tetra – Influenza Vaccine is an inactivated seasonal flu vaccine used to help protect against influenza. It contains influenza virus surface antigens selected for the relevant influenza season and is designed to stimulate the immune system to produce antibodies against influenza virus strains included in the vaccine.

Influenza can cause fever, cough, sore throat, body aches, headache and fatigue. Although many people recover without complications, influenza can become more serious in older adults, young children and people with certain underlying health conditions.

Influvac Tetra is used for influenza prevention rather than for treating an influenza infection that has already developed. People searching for Influvac Tetra price in Pakistan, availability and vaccination information can contact Impo Medic for current product information.

Influvac Tetra – Influenza Vaccine Uses

The primary use of Influvac Tetra is active immunization against seasonal influenza.

It is intended to help reduce the risk of influenza caused by virus strains represented in the seasonal vaccine.

Influenza vaccination can be particularly important for people who may have a higher risk of complications from influenza, depending on national vaccination recommendations.

These may include:

• Older adults
• People with chronic respiratory conditions
• People with cardiovascular conditions
• People with diabetes or other chronic metabolic disorders
• People with chronic kidney disease
• People with certain conditions affecting immunity
• Children and adults for whom seasonal influenza vaccination is recommended

Influvac Tetra does not treat an existing bacterial or viral infection and should not be considered a medicine for immediately relieving flu symptoms.

How Does Influvac Tetra Work?

Influvac Tetra is an inactivated influenza vaccine.

It contains selected surface antigens from influenza virus strains. These antigens cannot cause influenza in the way an active influenza infection does, but they allow the immune system to recognize important influenza antigens.

Following vaccination, the body develops an immune response and produces antibodies.

If the vaccinated person later encounters a related influenza virus, these antibodies can help the immune system respond more effectively.

Protection is not immediate. An immune response generally takes time to develop after vaccination.

Because circulating influenza viruses can change and vaccine composition is updated according to seasonal recommendations, influenza vaccination is generally considered on a seasonal basis.

Who Can Receive Influvac Tetra?

According to current product information, Influvac Tetra is indicated for adults and children from 6 months of age.

Whether vaccination is appropriate for a particular person should be determined according to official immunization recommendations and individual medical circumstances.

A healthcare professional should be informed about:

• Previous serious reactions to influenza vaccines
• Known allergies
• Current fever or acute illness
• Immune system disorders
• Medicines that suppress the immune system
• Bleeding disorders
• Pregnancy
• Previous neurological problems following vaccination

This information helps the healthcare professional determine whether vaccination should proceed normally, be delayed or require additional precautions.

Influvac Tetra Dosage and Administration

The usual dose for adults is:

0.5 mL

For children from 6 months to 17 years, the recommended dose in current product information is also:

0.5 mL

Children younger than 9 years who have not previously received a seasonal influenza vaccine may require a second 0.5 mL dose at least 4 weeks after the first dose.

The safety and effectiveness of this product in infants younger than 6 months have not been established.

The vaccine should be administered by an appropriately trained healthcare professional. Parents and patients should follow the vaccination schedule recommended by their doctor or vaccination service.

How Is Influvac Tetra Given?

The vaccine is administered by injection.

Current product information specifies administration by intramuscular or deep subcutaneous injection.

The appropriate injection site depends on age and individual circumstances. In adults and older children, the deltoid region of the upper arm is commonly used. For younger children, an appropriate thigh injection site may be selected.

Influvac Tetra should not be self-administered at home without appropriate healthcare supervision.

Influvac Tetra Side Effects

Like other vaccines, Influvac Tetra – Influenza Vaccine can cause side effects, although not everyone experiences them.

Common reactions can include:

• Pain at the injection site
• Headache
• Fatigue
• Muscle aches
• General discomfort
• Redness or swelling at the injection site

In younger children, irritability, drowsiness or reduced appetite may also occur.

Most routine vaccine reactions are mild and usually resolve without specific treatment within a short period.

Serious Allergic Reactions

Severe allergic reactions are uncommon but require immediate medical attention.

Seek urgent medical assistance if symptoms such as the following develop after vaccination:

• Difficulty breathing
• Swelling of the face, lips or throat
• Severe dizziness
• Widespread rash or hives
• Collapse or loss of consciousness

Vaccination should therefore be carried out in an appropriate setting where severe allergic reactions can be recognized and managed.

Contraindications and Precautions

A person should inform their healthcare professional about any known hypersensitivity to the vaccine ingredients or trace substances that may be present from the manufacturing process.

Influvac Tetra may contain traces of substances such as egg proteins, formaldehyde, gentamicin, polysorbate 80 and cetyltrimethylammonium bromide.

Current product information lists hypersensitivity to active ingredients, excipients or relevant trace components as a contraindication.

Vaccination should also generally be postponed in people experiencing a febrile illness or acute infection until the healthcare professional considers vaccination appropriate.

People with a history of serious vaccine reactions should discuss this history with their doctor before receiving another influenza vaccine.

Influvac Tetra and Pregnancy

Seasonal influenza vaccination can be important during pregnancy because influenza itself may cause complications in pregnant patients.

However, the decision regarding a particular vaccine should follow local immunization recommendations and the advice of a doctor, obstetrician or vaccination professional.

Patients should tell the healthcare professional if they are pregnant or think they may be pregnant before vaccination.

Influvac Tetra and Breastfeeding

Current product information indicates that the vaccine may be used during breastfeeding.

A breastfeeding patient should still inform their doctor or vaccination professional about their medical history and any previous vaccine reactions before receiving it.

Does Influvac Tetra Cause Flu?

Influvac Tetra is an inactivated influenza vaccine.

It does not contain active influenza virus capable of producing a typical influenza infection.

Some people can develop temporary symptoms such as headache, fatigue, muscle aches or injection-site discomfort after vaccination. These are vaccine-related immune reactions and should not automatically be interpreted as influenza infection.

It is also possible to develop influenza or another respiratory infection around the time of vaccination because vaccination cannot prevent every respiratory illness and immunity takes time to develop.

Why Is Seasonal Influenza Vaccination Important?

Influenza viruses can change over time.

For this reason, influenza vaccine composition is reviewed and updated for influenza seasons according to recommendations from health authorities.

Protection from a previous influenza vaccination also decreases over time.

Seasonal vaccination helps provide immune protection against influenza strains selected for the relevant vaccination season.

Patients should follow current national recommendations regarding the appropriate timing and frequency of influenza vaccination.
