Patented hepatitis B vaccine

At present, there are ten kinds of vaccines used to prevent twelve infectious diseases:

1. Measles vaccine: Measles vaccine is an attenuated live vaccine with mild vaccination response and good immune persistence. Babies can be vaccinated regularly after birth to prevent measles. ?

2. Poliomyelitis vaccine (referred to as poliomyelitis sugar pill): Poliomyelitis sugar pill is an oral vaccine preparation, white granular sugar pill, which is safe to inoculate. Taking sugar pills as planned after the baby is born can effectively prevent polio. ?

3. DTP preparation: it is a mixture of pertussis vaccine, refined diphtheria toxoid and refined tetanus toxoid, which can prevent pertussis, diphtheria and tetanus at the same time. ?

4. BCG: It is made of nontoxic bovine tuberculosis, which is safe and effective. Vaccination after birth is a reliable measure to prevent tuberculosis. ?

5. Japanese encephalitis vaccine: Japanese encephalitis vaccine infects hamster kidney cells with Japanese encephalitis virus, and after culture, the virus solution is harvested and freeze-dried to make attenuated live vaccine to prevent Japanese encephalitis. ?

6. Meningococcal vaccine: It is made of group A meningococcus, extracted by chemical method and freeze-dried. It is specially used to prevent epidemic cerebrospinal meningitis caused by group A meningococcus. ?

7. Hepatitis B vaccine: At present, there are two kinds of blood-borne hepatitis B vaccine and genetic engineering hepatitis B vaccine, both of which are used to prevent hepatitis B.?

Hepatitis B blood-borne vaccine is made by extracting HBsAg from the plasma of asymptomatic carriers of hepatitis B surface antigen (HBsAg), purifying and inactivating it, and adsorbing adjuvant. ?

Genetic engineering hepatitis B vaccine is a hepatitis B subunit vaccine, which is made by cloning the gene expressing surface antigen in hepatitis B virus into yeast by modern biotechnology, obtaining HBsAg subunit by cultivating this recombinant yeast, purifying it and adsorbing it with adjuvant. This new generation of hepatitis B vaccine has the advantages of safety and high efficiency. ?

Hepatitis A vaccine: an attenuated strain of hepatitis A virus, which has good immunogenicity and is harmless to human beings, is inoculated into human diploid cells, cultured, extracted and purified, and dissolved in balanced salt solution containing amino acids to prevent hepatitis A ...

9. Live mumps vaccine: inoculate the attenuated mumps strain into chicken embryo cells, culture, harvest virus liquid and freeze-dry. Can be used for preventing mumps. ?

10. rubella vaccine: It is cultured from human diploid cells infected by the attenuated rubella virus strain BPDⅱ Ⅱ, and the freeze-dried vaccine turns clear orange after being dissolved. Used to prevent rubella.
