Recently, the omicron variant was identified as a new mutated SARS-CoV-2 strain. Omicron seems to spread faster than the Delta variant but what how will Omicron impact the COVID-19 pandemic? And will COVID-19 vaccines work against Omicron?

COVID-19 is a pandemic which is caused by the virus SARS-CoV-2. When SARS-CoV-2 enters the body it infects cells which have ACE2. The immune system detects the SARS-CoV-2 particles and tries to prevent COVID-19. Sometimes this works but other times patients might experience severe forms of COVID-19. Over the past months, we learned a lot about COVID-19 and potential permanent damages (Long-COVID). Fortunately, COVID-19 vaccines largely prevent severe COVID-19 forms.
A couple of weeks ago, the Omicron variant was identified. The Omicron variant is a new SARS-CoV-2 variant which spreads fast. First data indicates that the Omicron variant is a highly infectious COVID-19 variant. Fortunately, COVID-19 symptoms caused by Omicron are overall not more severe compared to the Delta variant. Although COVID-19 vaccines are less effective againt Omicron, it seems like that booster shots might largely prevent hospitalization. Let's hope that the COVID-19 pandemic ends soon!
