Vaccine effectiveness against symptomatic Covid-19 from Omicron ranged 65%-75% two to four weeks after an mRNA booster, dropping to 55%-70% at five to nine weeks, and 40%-50% from 10 weeks.
People who are well but test positive for Omicron just need to self-test to discharge from the third day onwards, while close contacts are required to self-test daily before leaving their homes. Unwell cases will be placed under home recovery or treated in hospital.
Covid-19 vaccine effectiveness against symptomatic Omicron infection is estimated at between 0% and 20% after two doses, and between 55% and 80% after a booster dose.
Many poor and marginalised people, who often view the state and its agencies as hostile entities, have absorbed misinformation to fuel conspiracy views.
