They are still treating every vaccinated person who tested positive as a symptomatic patient. They are expecting and demanding 95% protection if the vaccinated are using Pfizer or Moderna. They are also expecting Pfizer to give 95% protection when Delta is more vicious and infectious than Alpha which was used to work out the 95% vaccine efficacyIn short P & M are useless.
