Know your enemy: Getting to grips with the COVID variants attacking Thailand

13 Sept 09:52 Key points summarised by AI
  • Thailand faces a severe third wave of COVID-19, driven by the recent detection and spread of three highly transmissible variants: British, Indian, and South African.
  • The South African variant (B1.351) is particularly concerning due to its rapid spread and significantly reduced efficacy against some vaccines, including AstraZeneca, which showed only 10.4% effectiveness in preventing mild to moderate infections.
  • The Indian (B1.617) and UK variants, both highly contagious, have also contributed to the surge, with varying vaccine effectiveness; Pfizer and AstraZeneca are effective against the Indian variant, while Sinovac and AstraZeneca show reduced efficacy against the UK variant.
