| What are the characteristics of lambda mutant strains spreading in 29 countries? Is the vaccine effective? |
China News Service, July 17th.
According to a report by Peninsula Chinese website, the mutated new coronavirus "Lambda", which was first discovered in Peru, has appeared in 29 countries
.
What are the characteristics of this widely spread mutant strain? What are the symptoms of infection? Is the vaccine effective against it?
Appeared in 29 countries
Appeared in 29 countries According to reports, the lambda strain was first reported in the capital Lima in August 2020, and the detection rate of new infections after April 2021 was 80%
.
At present, Peru has the highest per capita death rate from new crown pneumonia, with 596 deaths from the new crown virus for every 100,000 residents
.
According to a report published on the World Economic Forum website, one of the main reasons for the high numbers is the emergence of lambda mutants
According to the World Health Organization, lambda variants have been found in 29 countries.
The variants contain many mutations that can increase infectivity and risk
.
What are the symptoms of infection?
What are the symptoms of infection? According to The Times of India, the infection symptoms of the lambda mutant strain seem to be the same as the common symptoms of the new coronavirus, such as: cough, fever, loss of taste, loss of smell, body pain and shortness of breath
.
Experts recommend closely monitoring these symptoms and consulting a doctor as needed
June 14, World Health Organization announced that lambda is "worthy of global concern variants of the virus," the British Ministry of Public Health on June 23, also described as "variants under investigation"
.
Is the vaccine still effective?
Is the vaccine still effective? Many scientists mentioned that the "unusual combination" of lambda strains may make it more transmissible
.
There are seven mutations in the spike protein of the lambda mutant strain.
These mutations may promote the binding of lambda to cells and make it more difficult for antibodies to attach to fight the virus
.
A preliminary study at New York University’s Grossman School of Medicine looked at the effects of Pfizer and Modena vaccines on lambda variants
.
It was found that compared with the original virus, the number of antibodies produced by the vaccine was reduced by 2 to 3 times, but this was not a significant loss of neutralizing antibodies
The researchers concluded that mRNA vaccines such as Pfizer and Modena may still be effective against lambda variants
Focus on the new crown pneumonia epidemic
