VAXIGRIP SANOFI | Indication, Contraindication And How Given

VAXIGRIP SANOFI is a vaccine manufactured by Sanofi International Company that helps to protect the body against the influenza virus.

It should be used according to official recommendations.

When VAXIGRIP SANOFI has been injected, the body's defence system (immune system) produces antibodies against 3 strains of the influenza virus after about 2-3 weeks after injection but influenza can be caused by different versions of virus strains that can be changed every year, So scientists try to predict the strains that will be most likely for the coming year and using them to make up the year's influenza vaccine, so the body needs to be vaccinated each year.

The incubation period of the influenza virus is a few days, so if the body is exposed to the flu immediately after or before the injection of the vaccine, the disease is still developed.

This vaccine protects against flu from 6to 12 months, but may not fully protect all persons who are vaccinated.

Contraindication Of Giving VAXIGRIP SANOFI :

1-If the patient is allergic to

-                The active substances or any trace products found in this vaccine.

-                Any component such as eggs, neomycin, formaldehyde or octoxinol-9.

2-If a patient has an acute infection or an illness with a high temperature, the vaccination should be postponed until the patient has recovered.

The National Advisory Committee on Immunisation recommends annual vaccination for :

-Adults and children who have chronic disorders of the cardiovascular system or the pulmonary system.

-Patients with Diabetic Mellitus, renal dysfunction, haemoglobinopathies or immunosuppression.

-Children aged 6 months to 18 years who are receiving long-term aspirin therapy because of the risk for developing Reye syndrome after influenza.

In Case Of Pregnancy And Breast-Feeding :

In case there is no problem to take in pregnancy, it can be used at all stages of pregnancy, but it is better to be used in the second and the third trimester.

It may be used during breastfeeding after doctor consultation and the NACI states this vaccine is considered safe for nursing women.

In Case Of Neurological Disorders:

In this case, vaccination should be delayed till the disease process has been stabilized because Guillain-Barre` syndrome has been reported after influenza vaccination.

Therefore, the NACI and APCI avoid giving the vaccine to persons who are known to have experienced GBS within 6 to 8 weeks after previous influenza vaccination.

Before Vaccination, patients should take into consideration that the patient should tell the doctor if has a poor immune response or bleeding problem or bruising easily and the doctor will decide what should be done before vaccination.
