When will COVID-19 vaccine be available?

The world is doing everything to develop a vaccine against the coronavirus infection.

Researchers are working on about 200 COVID-19 vaccines. Some of them are already in the final stages of research.

Here is a list of vaccines with the most promising results in all three research phases.

Moderna

Country of origin - US

The type of vaccine is the RNA vaccine.

According to some studies, DNA and RNA vaccines may be safer and more effective than vaccines created by other methods.

Interim data showed that the vaccine was 95% effective.

The Moderna vaccine is expected to be available in limited quantities in the US by the end of the year and globally by early next year.

Pfizer / BioNTech

Country - US / Germany.

The type of vaccine is the RNA vaccine.

Interim data showed that the vaccine was 90% effective.

To be available in limited quantities in the UK by the end of the year.

Oxford University / AstraZeneca

Country - Great Britain.

The type of vaccine is a viral vector vaccine.

Molecular biologists use viral vectors to inject vaccine antigens into cells. The virus has been modified in such a way that the risk is minimized.

The results of the interim study will be known in a few weeks.

If the interim results are positive, a limited amount of the vaccine will be available by the end of this year.

Novavax

Country: US

The type of vaccine is a protein-based vaccine.

Virus-like particles, such as the empty shell of a virus, can mimic the structure and action without being infected because they do not have the genetic material of the virus.

If the third phase of the study is successful, the vaccine will be available in bulk in the second half of next year.

Janssen Pharmaceuticals (Johnson & Johnson)

Country: US

The type of vaccine is a viral vector vaccine.

If the third phase of the study is successful, the vaccine will be largely available in the second half of 2021.
