Vaccine Production

millions of people receiving them safely every year.  what is the vaccine? it goes through boundless and rigorous testing to ensure it is safe before it can be introduced in a country.

Each vaccine goes through screenings and analysis to determine which antigen should be used turn to an immune response.

This preclinical phase is done without testing on humans. An experimental vaccine is first tested in animals to evaluate its safety and potential to prevent disease.

If it shows a good response to animals then the vaccine is tested in humans.

Phase 1

The vaccine is given to young, healthy adult volunteers to check its safety, confirming immune response, determining the right dosage.

Phase 2

The vaccine is then given to more people to check an immune response. There are usually multiple trials are done on different age groups. changes are noticed in the people who got vaccinated as compared to the people who did not get vaccinated.
