What should I know about the Delta variant?

It is a version of the coronavirus that has been found in more than 80 countries since it was first detected in India. It takes its name from the World Health Organization, which names notable variants after letters of the Greek alphabet.

Viruses are constantly mutating, and most of the changes are not cause for concern. However, there are concerns that some variants could evolve to be more contagious, cause more serious illness, or defy the protection offered by vaccines.

Experts say the Delta variant spreads more easily due to mutations that make it better to attach to cells in our bodies. In the UK, the variant is now responsible for 90% of all new infections. In the US, it accounts for 20% of infections, and health officials say it could become the dominant type in the country too.

It is not yet clear whether the variant makes people sicker as more data needs to be collected, said Dr. Jacob John, who studies viruses at Christian Medical College in Vellore, South India.

Studies have shown that the available vaccines against variants, including the delta variant, work.

Researchers in England looked at how effective the two-dose vaccines AstraZeneca and Pfizer-BioNTech were, compared to the alpha variant first discovered in the UK

The vaccines were protective for those who received both doses but less so for those who received one dose.

Experts say it is important to be fully vaccinated. And that’s why it’s so important to make vaccines available around the world.
