BioNTech CEO Ugur Sahin advised CNBC on Thursday he’s “confident” the corporate’s Covid-19 vaccine with U.S. partner Pfizer is efficient against a coronavirus variant first identified in India.

The strain, often called B.1.617, contains two key mutations which were discovered individually in different coronavirus variants. The variant, additionally known as the “double mutant,” was first spotted in India, the place it is thought by some to be behind a latest surge in new Covid-19 circumstances there.

The variant has since been identified in different nations, together with the United States.

Sahin stated the German drugmaker has examined its two-dose vaccine, which is at the moment not accessible in India, against comparable “double mutants.” Based on these information, Sahin stated he feels assured the shot will nonetheless be protecting.

“We are evaluating [the strain] … and the data will be available in the coming weeks,” he advised CNBC.

“However, we had similar double mutants in our prior testing, and we are confident based on the data we had in the past that we might see a similar fashion of neutralization of this virus. But we will only know it if we have the data in our hands,” he added.

In February, Pfizer and BioNTech stated they were testing a third dose of their Covid-19 vaccine to higher perceive the immune response against new variants of the virus.

Sahin stated Thursday that researchers are seeing a decline in antibody responses against the virus after eight months.

“If we provide a boost we could really amplify the antibody response even above the levels that we had at the beginning and that could give us real comfort for protection for at least 12 months, maybe 18 months,” he stated.
