모더나 백신, 실험실 테스트서 델타 변이에도 예방효과
Moderna says its COVID-19 vaccine is also effective against the Delta variant that has sparked a global resurgence in cases.
Studies also show Russia’s Sputnik V vaccine is effective as well.
Lee Seung-jae reports.
With the Delta variant ravaging many parts of the world,… vaccine makers have been studying their vaccines’ respective effectiveness against the highly transmissible strain.
U.S. drugmaker Moderna on Tuesday released its study,… indicating that its vaccine showed a modest decrease in response compared to the original strain.
The study was conducted on blood serum from eight participants,… one week after they received their second dose.
The results showed an antibody response against all variants,… including Delta.
Data also showed the vaccine was far more effective in producing antibodies against the Delta variant than against the Beta variant,… first identified in South Africa.
While the study did not directly measure vaccine effectiveness,… the neutralizing antibody levels are said to be high enough to prevent disease.
The study added the mRNA vaccine generates a surplus of antibodies against the original strain.
Moderna’s study comes as the company earlier published research showing its vaccine produced neutralizing antibodies against the Alpha, Beta and Gamma variants.
A recent study by Moscow’s Gamaleya Institute,… which developed the Sputnik V vaccine showed the vaccine was highly effective against the Delta variant.
Sputnik V was shown to be 90-percent effective against the Delta variant,… compared to 92-percent efficacy against the original strain.
The Delta variant,… first identified in India, has now been reported in at least 92 countries,… and is expected to become the dominant variant worldwide.
