Novavax vaccine: effective, but not against South African variant | Digital Trends Spanish


The American company Novavax assured that the vaccine it makes against the coronavirus yielded an efficacy percentage of 89.3 points.

However, the company also claimed that its vaccine would not be as effective for the new variant of the disease discovered in South Africa.

Novavax has developed trials in Great Britain, South Africa, the United States and Mexico. He had just pointed out that the trial conducted in Great Britain with 15,000 individuals yielded an efficacy rate of almost 90 percent.

However, in a small trial carried out in South Africa, the percentage of efficacy was reduced to 50 points.

The data also indicates that many of the test participants became infected with the variant even after testing positive for COVID-19.

“We have the first trial (we are the first to do an efficacy trial) against a changing virus,” said Stanley Erck, president and CEO of Novavax.

While the researchers hoped that the variants could change the results of the trial, “the number of changes has been a bit surprising for everyone,” adds the executive.

Now the company hopes to soon test a new vaccine tailored to protect against this variant, known as B.1.351. “We will have to make new vaccines.”

This news has caused concern in the health authorities of the United States. The first infections with this new variant were just known. It would be two unrelated people from South Carolina.

This information comes after Moderna and Pfizer also found that their vaccines were less effective against the South African variant.
