Swine flue vaccine in Europe

LONDON (AP) - In a drive to vaccinate people against swine fever before winter several European governments that they will. Fast-track testing a new flu vaccine Add Some of those concerns. Experts about the safety and suitability of the vaccine doses.

European drugs agency of the European Union regulations on the body is to accelerate the drug approval process. Swine flu vaccine and for countries such as England, Greece, France and Sweden say they will start the vaccine after it greenlighted - may be within weeks.

In interviews with the relevant Press Dr Keiji Fukuda of the World Health Organization's influenza chief warns about potential hazards from The vaccine trial even if he has not stopped short of criticizing Europe's approach outright.

"One of the things that can not be compromised is the safety of vaccines," he said Friday. "There are some areas you can make a number of economic areas, but could you just Some try not economic. "

Flu vaccines are used in 40 years and many experts say extensive testing is unnecessary swine flu The new vaccines are: swine influenza virus.

But European officials will not know that any new vaccine causes fewer side effects. Until millions of people get shot. Also said the benefits of saving lives is worth the gamble.

"Everyone made the best they can in situations far from ideal," the Ratns Harvey-Allchurch. The spokesman for the European drug agency. "With the winter flu season near, we must ensure that a vaccine."

European flu vaccine is usually tested in several hundred to several weeks or months. Ensure that the immune system produces enough antibodies to fight infection.

However, to ensure that pork is the fastest-flu vaccine in Europe, drug agents. To help companies across many people in the test before you are approved vaccine.

Main problem is that rigorous testing by the difficulty in measuring the effective volume - Europe may see the vaccines are too weak. It is likely that vaccine, but until all threats are used in many people will not. Who know with certainty

Europe seems ready to use vaccine widely before acting on any of the major studies To prove it is safe and effective. Do not do drugs or vaccines European agency will inform all the basic safety testing done.

If the U.S. is more cautious approach: the government called Wednesday for the thousands of volunteers injected with the swine flu vaccine will begin testing in August evaluate vaccine safety, the U.S. officials that the results should be ready when the United States plans to Roll out a vaccination campaign in October.

Results from the American experiment will be limited for use in European countries from the United King - For example, empire they have plans to start vaccinating in August - before the U.S. trial data. Vaccines used in the United States will differ from those in Europe.

Some experts favor rapid response.

"In the lack of vaccine if the virus is very high for violence" said Leonard Marcus is a public health specialist at Harvard University. "If (the power) at any time necessary to ensure that no side effect, ironically trying to save a few lives many lives may be lost."

But critics say the dangers lurk in every inoculation strategy with robust test

Truncated data is influenza vaccine adjuvants components using anti-stretch mark ingredient used in some European influenza vaccine, influenza vaccine is not copyrighted in the United States to the mix.

There are also limitations in the data or the safety and effectiveness of adjuvants for vaccines for children under 3 and pregnant women - two of the most vulnerable groups in a pandemic - global scourge

Mass swine flu vaccination campaign will occur in the shadow of the 1976 swine flu fight disaster when hundreds of U.S. development Guillain-Barre. Group of symptoms, the disease has been paralyzing disorder vaccine.

Experts do not know why it happened but said the modern vaccine production techniques. Improvements since 1976 to avoid a similar occurrence some extensive testing before ". Vaccine is rolled out is significant.

"I can see no excuse not to test for safety before everyone" Anna George said a bioethics expert at Boston University.

If the vaccine proved to have dangerous side effects that may cause public backlash, especially in countries like the UK, many people remain suspicious of the vaccine because of unsubstantiated allegations linking the measles, mumps and rubella vaccine to the deep. knot Which could lead to millions of people refusing vaccination

When bird flu crisis, press the last several years, European drug agencies established specifically to approve the vaccine protocol. For use in a pandemic as soon as possible.

Agencies to submit information for the company. "Deceiving the H5N1 Avian Influenza vaccine use. The idea is to optimize the test before the world when it spread. Have struck drugs enables deployment of pandemic vaccine viruses in the last minute.

When the first swine flu vaccine available, European drug agencies will agree they are most dependent on information from bird flu. The two major vaccines are the same basic ingredients.

If the agency determined that avian flu information swine influenza viruses expected to work will see it said the spokesperson. Harvey-Allchurch.

Agencies to report on regular vaccines because of the rule - the normal controlling action in advance.

Fukuda said that all who associated with making vaccines from manufacturers to monitor unit A look at what steps can be to streamline the process.

"But no one disagrees that one of the absolutes, there can be no question that the vaccine is safe or not," he said.

Which reported that the swine flu virus does not produce enough of the key ingredients for vaccines. Which may limit how much vaccine. Sit network operations work to develop this new set of viruses that will work. Hope better.

Drugs as well as enabling Baxter International, GlaxoSmithKline plc, Novartis and Sanofi-Pasteur. But claim they can start shipping the first batches of vaccine soon.

British health officials have repeatedly said they will begin to vaccinate in August, as soon as the vaccine has been approved. Other European countries including Greece, France, Sweden, said they want to use the vaccine after it has been represented by green light. European Union but none other than the United Kingdom is expected to start filming Movie next month.
