Q. Are vaccinated and boosted people more susceptible to infection or disease with the omicron variant than unvaccinated people?
A. No. Getting vaccinated increases your protection against COVID-19. Sometimes, certain raw data can suggest otherwise, but that information cannot be used to determine how well a vaccine works.
As many Americans and others around the globe prepare for holiday travel and get-togethers, the omicron variant continues to be a concern. While the available data on transmission, vaccine effectiveness and severity of disease are still preliminary, here’s what we’ve learned so far.
It’s not known yet whether the omicron variant causes more or less severe COVID-19 than the delta variant, although some preliminary indications suggest omicron infections might be milder. A Facebook post nevertheless claims, without evidence, that the “toxicity” of omicron is 5 times higher than delta and that its mortality rate is higher.
Scientists are still learning about the omicron variant’s ability to spread or cause severe illness and the effectiveness of the current COVID-19 vaccines in fighting it. But a Facebook post misleadingly claims to list seven “symptoms” of the new variant, then suggests they are caused by the vaccines. The list actually refers to complications of COVID-19. Two of the listed conditions are rare adverse events associated with the vaccines.
On Nov. 24, South Africa told the World Health Organization that amid a recent increase in COVID-19 cases, it had identified a new variant — later named omicron — with a high number of mutations, raising concerns that it could spread more easily than other variants of the coronavirus. We’ll go through what we know so far about omicron.
