Veterinary Industry of Vietnam react to warnings of the UN Food and Agriculture Organization of the avian influenza virus can transform serious outbreak.

Nam Nguyen exchange rapidly with Dr. Van register, Head of Epidemiology Department of Animal Health of Vietnam, from Hanoi, said Dr. Van Sign:

TS Application for registration: bird flu vaccine now has problems of epidemiological characteristics, the virus has changed is the H5N1 clade (branch) 2.3.2 China has done the vaccine. This problem is very high risk, if you are not monitoring for early detection processing time, it will be spread without the vaccine will be very dangerous.

From May 9 / 2010 H5N1 virus had changed, before bird flu virus circulating in Vietnam and China are clade clade 2.3.4 is now 2.3.2. This is a very important issue, said a pandemic would spread to the extent it is not so, but still alert.

Nam Nguyen said Vietnam Information has stopped vaccinating poultry in northern and central ... what about in the South actually like?

TS Application for registration: The problem is that scientists find anti-viral vaccine for this new clade. We are interested in whether a vaccine to be prepared for vaccination because of round 1 round 2 were not vaccinated then. Now bird flu vaccines primarily given to the southern provinces, because this area is the virus H5N1 clade 1 vaccine-RE5 is effective vaccination. We have vaccinated 50 million doses and prepare 60 million doses needed for phase 2.

Wait for new vaccines

Nam Nguyen: The spread between regions in Vietnam are unavoidable as happened in the past, vaccinating older types can be wasteful and inefficient?

TS Application for registration: This is for the North instead! South vaccine still works normally be vaccinated against epidemic and in the South is the next vaccination and sampling to check the virus in the South is changing or not. We reported the minister (MARD) Epidemiological features of virus circulation in the South is still the clade 1 has been vaccinated. Particularly clade 2.3.2 does not work, we stop injecting, we're waiting to see China has devised the new vaccine or not either Mexico or another country are more domestic vaccine research. This is a problem we are interested in leading.

Nam Nguyen: Dear Dr., in the context of the current avian influenza was detected changes in the North is no longer vaccinated, while in the South is still vaccination. So the fact Vietnam is dealing with the risk of bird flu outbreaks like?

TS Application for registration: Of course now no longer a vaccine is to monitor their time ... occur in small outbreaks, but their findings will collapse sooner or recompiled. We have reported outbreaks in Phu Tho, we found early and treated immediately, it does not spread further to other places. There is no prophylactic vaccine, the problem is that we must strengthen surveillance systems, early detection, treatment destroyed immediately, but if we neglect to spread to other places where it will spread into higher great service. More than a year we do not have any outbreak of bird flu spreading to humans, so I think virulent virus to infect people was not high, so the past may no patients infected with H5N1.

Nam Nguyen: Thank you, Dr. Van registration interview.
