Product Detail

Influenza Vaccine (Split Virion), Inactivated 
Influenza Vaccine (Split Virion) is a preparation made from the prevalent strains of influenza virus type A and type B recommended by WHO and approved by the NRA. The strains of influenza virus type A and type B are grown separately in embryonated chicken eggs. After cultivation, the virus suspensions in allantoic cavities are harvested, inactivated, purified,disrupted and repurified to make the vaccine. It is used to prevent the infections of the prevalent strains of influenza viruses.

It complies with the test for mycoplasmas (Appendix XII B). 
2. 2. 3. 6   Tests for adventitious avian leucosis viruses 
Neutralize the seed virus with corresponding sybtype specific antiserum. Inoculate the neutralized material onto SPF embryonic fibroblast cell cultures. After incubation, the cultures are tested by ELISA.  The result shall be negative. 
2. 2. 3. 7   Tests for adventitious avian adenoviruses 
Neutralize the seed virus with corresponding subtype specific antiserum. Inoculate the neutralized material onto SPF embryonic hepatic cell cultures. After incubation, the cultures are tested for avian adenoviruses type I and type III by suitable serologic methods, respectively. All the results shall be negative. 
2. 2. 4   Storage of virus seed lots 
The freeze-dried virus seeds shall be stored at or below -20℃ , the liquid ones shall be stored at or below - 60℃ . 
2. 3   Monovalent vaccine bulk 
2. 3. 1   Virus inoculation and cultivation 
Inoculate a quantity of appropriately diluted virus from working seed lot into the allantoic cavities of embryonated eggs. Each strain of influenza virus shall be inoculated at the same virus titer. Incubate the inoculated eggs at 33-35℃ for 48-72 hours. The remaining thawed seed virus, if any, is not allowed to freeze for further use. 
2. 3. 2   Virus harvest 
After incubation, collect the living embryos and cool at 2-8℃ for a period of time. Harvest the allantoic fluids into containers. Take a sample from each of the containers for control tests. 
2. 3. 3   Control tests on allantoic fluid harvests 
2. 3. 3. 1   Mircobial limit test 
The "Bacterial, fungi or yeasts count"  (Appendix XII G) shall apply. 
The number of microorganisms shall be less than 105 CFU/ml and the test for Salmonella paratyphi B shall be negative. 
2. 3. 3. 2   Haemagglutinin (HA)  titer 
The HA titer shall be not less than 1: 160 determined by haemagglutination method. 
2. 3. 4   Allantoic fluid harvests pooling 
The qualified allantoic fluid harvests of monovalent influenza virus in each of containers can be pooled into a monovalent virus pool. 
2. 3. 5  Inactivation of virus 
Virus inactivation shall be performed within the prescribed range of the protein content. Add formaldehyde into the monovalent virus pool to the final concentration of not more than 200 μg/ml for virus inactivation at an appropriate temperature for a period of time. At the end of inactivation, take a sample from each of the virus inactivation containers immediately to perform the validation test for virus inactivation and the test for bacterial endotoxin (A quantity of formaldehyde solution may be added for virus inactivation after purification) .
