Herd immunity against COVID-19 still elusive in Japan

Nikkei reported on a growing consensus in the medical community that vaccinating 70% of the population against COVID-19 will probably not be enough to establish herd immunity in view of the rapid spread of the highly contagious Delta variant. Most public health professionals now believe eight or nine out of ten people will need to be inoculated to ensure that a significant portion of the population becomes immune to the virus. Because 90% of the people aged 12 or higher who are currently eligible to receive the Moderna or Pfizer vaccine will need to be vaccinated to achieve an overall 80% immunization rate, the experts insist that achieving the goal will not be easy and that various incentives and campaigns must be devised to encourage hesitant people to get vaccinated.
