Kinumpirma ng OCTA Research Group na malaki ang posibilidad na tatlong beses na mas nakahahawa at hindi tinatablan ng bakuna ang Omicron variant ng COVID-19 kumpara sa delta.
Gayunman, nilinaw ni OCTA Research Fellow, Father Nick Austriaco na batay sa preliminary data mula South Africa, ay maaaring hindi gaanong nakamamatay ang Omicron.
Ayon kay Austriaco, karamihan sa mga nagkakasakit sa South Afirca ay mas bata habang hinihintay pa nila ang datos mula sa nakatatandang populasyon.—sa panulat ni Drew Nacino
70% of them do not need oxygen po and this is very different from Delta experience that we experienced through out the world and the last few months in the Philippines. we have 31% require oxygen and 70% do not require oxygen and what is striking is that 10 of the 11 people who needed oxygen are unvaccinated and again what is suggest is that if you are vaccinated this will protect you from severe disease and hospitalization.
