Thailand: Herd immunity against virus at 50%

  • About half the population has now acquired immunity against Covid-19 but this remains well short of the government’s 80% target, according to the Department of Disease Control (DDC).
  • Dr Chakkarat Pitayowonganon, director of its epidemiology division, said around 10% of the country’s 67.5-million people are estimated to have contracted the virus so far.
  • When combined with those who have received two doses of vaccine plus a booster shot, those with immunity against Covid-19 should account for about 50% of the population.
  • Experts say that daily caseloads could rise to 50,000 to 100,000 following Songkran.
  • Dr Chakkarat said the initial post-Songkran infection rate has fallen slightly but this may be due to fewer RT-PCR and antigen tests having been carried out.
