I dont know how it is produced but hope my answer helped u

Answer 2

Hi friend,

Vaccines are made using the disease-causing virus or bacteria, but in a form that will not harm your child. Instead, the weakened, killed, or partial virus or bacteria prompts your baby’s immune system to develop antibodies, or defenders, against the disease.

Once it is determined how the virus and bacteria will be modified, vaccines are created through a general three-step process:

1. Antigen is generated. Viruses are grown in primary cells, or on continuous cell lines; bacteria is grown in bioreactors.

2. Antigen is isolated from the cells used to create it.

3.)Vaccine is made by adding adjuvant, stabilisers and preservatives. Adjuvants increase immune response of the antigen; stabilisers increase the vaccine’s storage life; and preservatives allow for the use of multi-dose vials.

HOPE THIS HELPS YOU:-))
