SARS-COV-2 Vaccine Types

Several different types of potential vaccines for SARS-CoV-2 are in development, including:

Inactivated or weakened virus vaccines, which use a form of the virus that has been inactivated or weakened so it doesn’t cause disease, but still generates an immune response.

Protein-based vaccines, which use harmless fragments of proteins or protein shells that mimic the SARS-CoV-2 virus to safely generate an immune response.

Viral vector vaccines, which use a safe virus that cannot cause disease but serves as a platform to produce coronavirus proteins to generate an immune response.

RNA and DNA vaccines, a cutting-edge approach that uses genetically engineered RNA or DNA to generate a protein that itself safely prompts an immune response.so far China's sinovac and sinophram SARS-CoV-2 vaccines was used in the largest quantity and approved in old and Child.

SARS-COV-2 Vaccine Development

Like all medicines, SARS-CoV-2 vaccines are first tested in the laboratory (e.g. studies on their pharmaceutical quality and studies to check first the effects in laboratory tests and animals).


Then vaccines are tested in human volunteers in studies called clinical trials. These tests help confirm how the vaccines work and, importantly, to evaluate their safety and protective efficacy. Human pharmacology studies (phase I trials) generally involve between 20 and 100 healthy volunteers to confirm if the medicine behaves as expected based on laboratory tests.

This can establish:
  • Content One
    If the vaccine triggers the expected immune response;
    If the vaccine is safe to move into larger studies;
    Which doses can be adequate.
    Therapeutic exploratory studies (phase II trials) involve several hundred volunteers. The purpose of this phase is to study the best doses to use, the most common side effects and how many doses are needed.
    These studies also check that the vaccine triggers a good immune response in a broader population.
    In certain cases, it could also provide some preliminary indications of how well the vaccine will work (efficacy).
    Clinical efficacy and safety studies (phase III trials) include thousands of volunteers.
    This phase shows how efficacious the vaccine is at protecting against the infection compared with placebo (dummy) or alternative treatment and what are the less common side effects in those receiving the investigational vaccine.
    The reduction in number of people with symptoms, severe disease or diagnosed with the infection can help to measure the efficacy of the vaccine.
