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.

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.
