The process of producing a highly purified Zika vaccine.

Abstract

This invention involves purifying the Zika vaccine by increasing the viral load. Zika is prevented by culturing verocells in a hyperflask, which provides more surface area for cell attachment, in order to produce a Zika vaccine. High purity is achieved by passing the sample through flow-loaded chromatography and collecting the fractional collection layer. The process of preparing the leaves at the appropriate time includes diafusion with vivasapin, which helps to remove formalin and... The high concentration of the Zika vaccine makes dosing formulation easy.

Claims

1. The process of producing a highly purified Zika vaccine involves a step of increasing the viral load. Zika; purification of the Zika vaccine; formalin disinfection; and formalin removal. It has the following specific characteristics: a) Increase the amount of Zika virus by culturing verocells in hyperflask for 4-5 days, then wash with... Prepare the cell culture medium using Minimum Essential Media (MEM) 2-3 times, then add... Zika virus strain SV0010-15 (15 CVD) at the ratio of viral particles to target cells. (Multiple of infected persons: MOI) 0.01 in a carbon dioxide incubator at 37 degrees Celsius for 90 minutes. Next, add serum-free cell culture medium, and then collect the viruses for further processing. pure b) The cell culture medium containing the Zika virus was refrigerated and separated using a refrigerated centrifuge. Centrifuge at 4,000-5,000 times the force of gravity (g) for 10-15 minutes and filter using flow filtration. Tangential flow filtration (TFF) using a membrane involves cutting out a portion at a size of 500 kilodaltons and then adding more. Benzonase endonuclease enzyme, 15 units / milliliter (IU / ml) at 4°C. 5 degrees Celsius for 18-19 hours to eliminate the DNA of the verocells. c) Refining the Zika vaccine using chromatography, by placing it in a 20-gauge column. A volume of 39.2 milliliters (39.2 cm³) was used, after the virus was pretreated with 0.5 mol of sodium chloride (NaCl). Load at a flow rate of 298-299 cm³ / hour. Collect fractions 1-7, combine them, and then... Inactivated by formalin. c) Remove formalin using Viva Spin by centrifuging with a refrigerated centrifuge. Centrifuge at 4,200-5,000 times the force of gravity (g) for 30-40 minutes. f) Add 10% stabilizer, where the stabilizer is a sucrose mixture. A 6% concentration of phosphate buffer saline (PBS) with the pH adjusted. That equals 7.

4. c) Next, prepare a dosage formulation by mixing the Zika vaccine with alum adjuvant.

2. The process for producing a highly purified Zika vaccine, as per Patent 1, which includes a cell culture medium. Minimum Essential Media (MEM) is recommended to include 5% Fetalbo Wine Serum.

3. The process for producing a highly purified Zika vaccine, as per Patent 1, which involves the storage of the Zika virus. After appropriate dosing, samples were collected on days 4 and 6 after supplementing the cell culture medium without fetalbovine. Serum (serum-free medium) 4. The process for producing a highly purified Zika vaccine, as per Patent 1, which includes inactivation. For treatment with formalin, use a concentration of 0.05% formalin for 7 days at 22 degrees Celsius.

5. The process for producing a highly purified Zika vaccine, as per Patent 1, which VivaSapine (Viva The appropriate spin (spin) size used for formalin removal should be 100 kilodaltons (Kda).

6. The procedure for producing a highly purified Zika vaccine, as per Patent 1, which involves dosing and formulation. The ratio of Zika vaccine to alum adjuvant should be set at 5 micrograms. Per 250 micrograms.

7. The use of processes to produce a high-purity Zika vaccine in accordance with any one of claims 1 through 6. For the production of Zika vaccines, to be used in the prevention of Zika virus infection.
