“Possibility of becoming more contagious and reducing the effectiveness of the vaccine due to protein mutations”
The ‘B1525 mutation’ confirmed 280 cases of infection in 19 countries

The spread of the mutant virus COVID-19 is accelerating.

Shortly after the creation of a rare and more contagious virus, B1525, derived from a British mutation, spread to 19 countries around the world.

Let’s take a look at the details with reporter Jo Soo-hyun from the International Department. welcome.

Let’s start with the identity of the mutant virus B1525.

The B1525 mutation was first detected in Nigeria and the United Kingdom in December last year.

It is derived from an existing British mutation.

It is similar to the British mutation, but is characterized by additional mutations in the protein.

A mutation in the spike protein called E484K has been reported to evade the immune system.

Therefore, it is analyzed that there is the possibility that the immune response is lower and more contagious than the existing British mutation.

The South African mutation also carries the E484K mutation, raising concerns that a cure for COVID-19 could be reinfected or that the vaccine would be less effective.

Disabling the function of the spike protein can prevent infection, which is why most vaccines target the spike protein.

If the mutation changes the structure of the spike protein, the vaccine may be less effective.

If so, how far has the B1525 mutation spread?

[기자]

So far, it has been confirmed in Europe, North America, Africa, the Middle East, and Southeast Asia.

A total of 280 cases of infection have been reported in 19 countries.

Last night the news came that the first case of contagion was confirmed in Germany.

A local diagnostic company in Germany says at the Berlin airport that it has confirmed that a resident of Saxony has been infected with the B1525 virus.

Consequently, since the beginning of this year, all corona 19 diagnostic testing centers are re-examining confirmed cases for a mutant virus infection.

In Italy, the B1525 virus was first introduced last month.

Combined with the rapid spread of existing mutations in the UK, it is becoming increasingly difficult to answer.
