Vaccinated people usually become infected with Omicron, too, because of a number of features of the strain. Norwegian scientists have described the most common signs of infection in vaccinated people, Eurosurveillance writes.

The scientists analyzed an outbreak after a Christmas party at a restaurant, where 81 of 110 attendees were found to have omicron. At the same time, about 9% of those present were vaccinated, and analysis of their data allowed the authors to identify the 8 main symptoms of the strain in fully vaccinated people.

Thus, the most common signs turned out to be:

  • cough,
  • runny nose,
  • fatigue,
  • sore throat,
  • headaches,
  • muscle aches,
  • fever,
  • sneezing.

Some patients also had decreased appetite, taste, sense of smell, and difficulty breathing. Abdominal pain was a much less common symptom.
