The total body wants that the companies give at least 10 percent of their production or offer reduced prices of the poor countries which could differently be left without vaccines if there is a sudden sudden rise in the request. But some are skeptics about what such an engagement could mean for their business.

I put 't thinks that all the answers are there still, Swiss spokesperson said Eric Althoff de Novartis pharmaceutical AG of giant.

U.N. Ban Ki-moon general secretary, who met 30 important pharmaceutical manufacturers, called Tuesday for total solidarity by confronting the disease. Solidarity must mean that all has access to drugs and the vaccines that, it added.

The only principal pharmacist who was publicly of agreement on the request Tuesday of WHO was PLC of Great Britain 'of S GlaxoSmithKline, which indicated it would give 50 million amounts in a pandemia and offers more than WHO could buy with a discount for the poor countries.

A second pharmacist only of the capacity with limited production indicated that it would share half of his vaccinic amounts. The civils servant of WHO refused to identify the company because the business has to be still concluded.

Moreover smaller manufacturers vaccinic of the countries in the process of development also promised to share 10 percent of their vaccines with the U.N at the cheaper prices.

I can reassure you that I received the journalists known as very serious Chan Dr. Margaret of managing director, engagements WHO after having met the pharmacists. Very close, the ministers of health of everywhere in the world collected for WHO 'the S annual and discussed how to approach the demonstration.

The influenza of pigs was confirmed in more than 9.830 people in at least 40 countries, with the majority of the cases in Mexico and the United States. This figure does not include Taiwan which brought back its first case confirmed Wednesday. The total toll of death was at least 83 - 74 in Mexico, seven in the United States, one in Canada and one in Costa Rica.

One expects that the incidence of a pandemia - a total epidemic - is worse in the poor countries, where the people with other diseases such as SIDAS and the malaria are more likely influenza of pigs and national systems of health can less answer.

Many rich countries - including/understanding Great Britain, Canada, Denmark, France and Switzerland - already concluded from the businesses with the manufacturers vaccinic who will promise million universal vaccines to them as soon as they 'about available.

Others the companies which attended the meeting of Geneva, including Sanofi-Aventis and Baxter International, could not immediately be reached for the comment.

The manufacturers gained 't can start to make the vaccine until mid-July as soon as possible, forecasts that the posterior preceding ones of weeks, according to an group of expert assembled by WHO. That will then take months to produce the vaccine in great quantity.

The virus of influenza of pigs does not develop very quickly in the laboratories, making it difficult so that the scientists obtain it with the principal ingredient needs for a vaccine, actions of seed of the virus, WHO said.

The experts did not also find any obviousness which the regular vaccines of influenza offer any protection against the influenza of pigs.

They estimated that under the best conditions, the pharmaceutical companies could produce almost 5 billion amounts of vaccine of influenza of pigs per year after complete production of beginning.

An expert, however, thought 5 billion evaluation of amount was too optimistic.

Us should go in front of par with the production as quickly as possible, but should be to us careful about the forecasts, said David Fedson, an expert vaccinic and former medical professor at the university of Virginia.

Chan informed that it would be impossible to produce enough vaccine for each of the 6.8 billion people on planet.

In any case, the production of a universal vaccine would be a play, because it would carry production capacity for the seasonal vaccine of influenza which kills to 500.000 people every year. Some experts wondered whether the world needs really a vaccine for a disease which seems soft up to now.

The United States Secretary Kathleen Sebelius of health services and social affairs said Tuesday the United States judged that it had a responsibility to make sure that two antiviral drugs and any new vaccine are also available to the poor countries. The United States up to now abstained from to reserve any new vaccine.

Sebelius indicated that the United States functions to thus amplify its capacity to produce for the seasonal vaccines of influenza these factories could commutate with the constraint of universal influenza of pigs so necessary.

In this moment we did not place from the orders of, of vaccine the journalists called by Sebelius in Geneva. It remains so much uncertainty about this virus which it is really premature that we make even a determination how much people would be suitably vaccinated, in which order, how much amounts would be required.
