According to foreign media reports, a new study published in biorxiv by scientists from the University of Tokyo in Japan recently pointed out that,The COVID-19 strain Lamuda (Lambda) discovered in Peru for the first time is not only more infectious but also reduces vaccine protection.
It is reported that the Lamuda strain was first discovered in Peru. Over the past two months, more than 80% of the confirmed cases of COVID-19 infection in Peru were infected with the Lamuda strain.
At present, the strain has spread in dozens of countries such as Peru and Chile in South America, Britain in Europe, Canada in North America and Australia in Oceania, which has attracted the attention of health officials in many countries.
Japanese scientists found three mutations in the spinous process protein of ramda virus strain in the laboratory,Rsyltpgd246-253n, 260 l452q and f490s. These mutations contribute to the neutralization of the virus against the antibody induced by the vaccine.
In addition, the researchers found that,The other two mutations, t76i and l452q, help to make the ramda strain highly infectious.
Although it is not clear whether the ramda strain is more dangerous than the delta strain now prevalent in many countries, it is likely to be a potential threat and should be paid more attention to.
