Although for years the authorities recommend a flu shot at least to certain groups of people may be more affected by the disease the recent swine flu outbreak in Mexico has put the issue again today.

The flu vaccine is made from the three strains or variants of the virus to a panel of the World Health Organization considered to be more active each year.

Manual inoculation of huevosEstas strains often originate in Asia and must be reproduced in sufficient quantity for delivery to the laboratories that will manufacture the vaccine, something that only we know by now done using fertilized chicken eggs, which are inoculated with the virus either by hand or machine, and those for 48-72 hours to remove the amniotic fluid to isolate the virus that has been played there during that time.

Delivery of the "virus of reference for laboratories typically occurs in late March, and once there, you have to play again this virus in sufficient quantity to create as many doses of vaccine will be manufactured, extracted from Eggs which have been reproduced, and kill to make the vaccine that must then be packaged and distributed.

This whole process makes vaccination campaigns can never start until October.

The problem with the outbreak emerged in Mexico that has been caused by a variant of the virus has appeared in a place that was not expected and at a time that was not expected and no time to make a specific vaccine, a process it would take at least about three months, so we have to see how the quarantine and prophylactic protocols being implemented, and trust in the effectiveness of antivirals for treatment.

As is done in the influenza vaccine is a more detailed explanation of this process, a process that also have to start from scratch each year by the great capacity to mutate with the virus, which makes the vaccine a years is usually not effective to the next in Vaccine Manufacture: Egg-Based Vaccine Production is further details, but in English.
