Why herd immunity could be an impossible goal for Thailand

13 Sept 22:08 Key points summarised by AI
  • Prominent virologist Dr. Yong Poovorawan dismisses the possibility of achieving herd immunity for COVID-19, citing the virus's rapid mutation and common breakthrough infections.
  • International examples from Israel and Singapore show that high vaccination rates do not prevent new surges in infections, necessitating booster shots and challenging the concept of population-wide immunity.
  • Unlike diseases such as measles, COVID-19's ability to quickly mutate into vaccine-blunting variants makes sustained herd immunity unachievable, comparing it to diseases like tetanus that require regular control.
  • Despite the unlikelihood of herd immunity, experts strongly urge vaccination as it significantly reduces the severity of symptoms, hospitalization, and death, ultimately transforming COVID-19 into a more manageable respiratory illness.
