Abdala Vaccine 92% Effective Against Coronavirus


Abdala, technical name CIGB-66, is a Covid-19 vaccine.

Its scientific title is “Phase III, multicenter, randomized, double-blind, placebo-controlled clinical trial for the evaluation in adults of the efficacy, safety and immunogenicity of the vaccine candidate CIGB-66 against SARS-CoV-2. (COVID-19)”

Its Issuing authority and the primary sponsor is Center for Genetic Engineering and Biotechnology in Havana, Cuba (CIGB)

Center for Genetic Engineering and Biotechnology in Cuba developed this vaccine.  The reason behind its name is the patriotic drama by Cuban independence hero Jose Marti.


What is the Vaccine’s Target?


What is the Vaccine Type?

Protein Subunit


What is the Route of Administration?

vaccine intramuscular


Via Intramuscular Route


Mechanism of Action

What is the reported efficacy of Abdala Vaccine?

On June 22, official Cuban government sources announced that the results of an initial study by the Cuban Center for Genetic Engineering and Biotechnology. They found the vaccine, administered in 3 doses spaced 2 weeks apart, had a 92.28% efficacy rate at preventing COVID-19.

More Information about Vaccination 

What is Vaccination?

Vaccination is a simple, safe, and effective way of protecting people against harmful diseases, before they come into contact with them. It uses your body’s natural defenses to build immunity to viral and bacterial infections and makes your immune system produces more antibodies to face these antigens.

Vaccines make your immune system ready to create antibodies, just as it does when a certain disease attacks our body. However, because vaccines contain only killed or weakened forms of germs like viruses or bacteria, they do not cause the disease or put you at risk of its complications.

Route of Administration of Most vaccines are by an injection, but some are orally (by mouth) or sprayed into the nose.


Why is Vaccination Crucial?

To begin with, vaccination is a safe and effective way to prevent disease and save lives now more than ever. Today there are different vaccines available, produced by different companies to protect against coronavirus.

When we receive the vaccine, we aren’t just protecting ourselves, but also those around us. Some people like those who are seriously ill. They can’t get certain vaccines so they depend on the rest of us to get the vaccines in order to help reduce the spread of disease. This is also known as “Herd Immunity”

Therefore, during the COVID-19 pandemic, vaccination continues to be critically important. The pandemic has caused a decline in the number of children receiving routine immunizations, which could lead to an increase in illness and death from preventable diseases.
