Omicron: what are the most recurrent symptoms in vaccinated people who have been infected?

the essential
A Norwegian study, which looked closely at a focus of contamination, looked at the symptoms that were felt by vaccinated people. However, this research affirms that the Omicron variant has a capacity for “high transmissibility” including in vaccinated people.

In Oslo (Norway), a laboratory relied on a Christmas party, organized by a works council, to closely study the symptoms associated with the Omicron variant, particularly in vaccinated people. Flashback: on November 26, in the Norwegian capital, several dozen employees gathered in a restaurant for the end-of-year festivities. One of the participants, tested positive for Covid-19, infects his colleagues. We will learn later that the employee, back from South Africa two days before the party, was infected with the Omicron variant, which is particularly contagious.

The participants were eventually contacted by the Norwegian Institute of Public Health (NIPH). In a study published on the website Eurosurveillance, the researchers say that 99% of the 111 people surveyed received two injections of the vaccine that uses messenger RNA technology. The scientists took a close interest in the symptoms described by the patients questioned. 81 of them said they had experienced symptoms. Cough (for 83% of respondents), runny nose (78%), fatigue (74%), sore throat (72%), headache (68%) and fever (54%). Only 12% of those questioned claim to have felt a loss of smell and 33% a loss of appetite. 23% of people questioned indicated that they had felt a loss of taste.

The NIPH calls this investigative work a “preliminary study”: the results that have been exposed in this study should be taken with caution. The researchers say, however, that it reaffirms the idea of ​​”high transmissibility” of the Omicron variant “even in vaccinated people”. The NIPH hypothesizes that vaccination would have made it possible to “reduce the risks of serious forms of the disease”: “none of the patients questioned was hospitalized, at least until December 13”, i.e. nearly 15 days after the first proven cases of Covid-19.
