What are the symptoms of Omicron infection in people who have received 2 doses of the vaccine?

According to Mr. Tim Spector, Professor of Genetic Epidemiology at King's College London (UK), head of the Covid-19 symptom research application, called ZOE, during the outbreakOmicronIn the UK, all people infected with Omicron have recently had "two or three doses of the vaccine".

Notably, evidence suggests that people who have received three doses of the vaccine can still get infected with Omicron, but the severity of the disease is significantly reduced.

Speaking in his latest video, Professor Spector explained the symptoms of Omicron infection in people who have had 2 or 3 doses of the vaccine.

Mild cold-like symptoms

Professor Spector said data from the app suggested about half of cases were being "missed" because people did not present with "classic" Covid-19 symptoms.

Symptoms of Omicron infection are likely to be very similar to mild symptoms of Delta variant infection in vaccinated people.

Early signs “suggest that Omicron is causing breakthrough infections in vaccinated people, but it is causing milder, cold-like symptoms,” said Professor Spector.

“We estimate that between one-third and one-quarter of colds are actually Covid-19,” the professor added.

If you've been vaccinated and start sneezing or coughing a lot for no apparent reason, you should stay home and get tested for Covid-19.

According to the team behind the ZOE app, if you've been vaccinated and start sneezing or coughing a lot for no apparent reason, you should stay home and get tested for Covid-19, especially if you live or work around people at higher risk.

From an event where 16 out of 18 people attending a party were infected with Omicron in the UK, Professor Spector found that there were four main symptoms: nausea, mild fever, sore throat and headache.

Professor Spector said that while none had needed to see a doctor or go to hospital, they had all received “two or three doses of the vaccine”. The fact that none had needed medical attention suggested that the vaccine had clearly reduced the severity of the disease.

In addition, Dr. Elad Maor, a cardiologist at Sheba Medical Center (Israel), was also infected with Omicron despite receiving three doses of the Pfizer vaccine, and reported three symptoms.

He began experiencing symptoms within a few days of exposure to the sick person, including: Fever, muscle aches and sore throat.
