Coronavirus variant B.1.1.529 (Omicron)

Initial data shows that the Omicron variant is at least three times more infectious than the Delta variant.

The Omicron variant also endangers people who have vaccine protection and those how have recovered from the disease more than before. According to the initial data of the epidemiologists of the United Kingdom, the effectiveness of using the 2-dose vaccination scheme in preventing symptomatic coronavirus is 0-20% and the 3-dose one (after a booster dose) 55-80%. The effectiveness of recovery against getting infected with Omicron is about 20%, according to the current data. This means that the risk of repeat infection is three to five times more likely than with the previous coronavirus variants.

The most effective protection against the Omicron variant currently on offer is a booster dose after this the risk of infection is up to 80% lower than it is for unvaccinated people.

The Health Board has detected the regular symptoms related to the coronavirus, like muscle pain, sore throat, coughing and runny nose, in the Omicron variant cases in Estonia.

Infected persons who have mild symptoms should get tested when there is even a slightest suspicion. An unvaccinated person can get infected more severely. As the Omicron variant has an infection potential several times higher than the Delta variant, one infected person with mild symptoms can transmit the virus to more than ten people.

According to the monitoring study of the University of Tartu, 82% of the residents of Estonia have a contact with coronavirus antibodies, which also might affect the severity of the symptoms.

It has been estimated that the effectiveness of the vaccine after administering a recent booster dose is good. The Scientific Advisory Board of Estonia assesses the protection level of the vaccines to still be effective. The vaccines continue to be effective in reducing severe cases and deaths.

If you have already been vaccinated but three months have passed since the course of vaccinations, get a booster dose. With the Janssen vaccine it is already possible to get a booster dose two months after vaccination.

The PCR tests widely in use can still detect the infection, including the Omicron strain, just as we have seen with other variants. The initial data suggests that rapid antigen tests can identify an infected person.

• Vaccination, hand washing, keeping a distance in public spaces, and wearing a mask help to contain the spread of the virus.
• Stay home if symptoms of any infection occur! Consult with the family doctor and head to testing at first opportunity. Read more about the testing opportunities on the web page of public testing, koroonatestimine.ee.
• All members of the household, including those that have been vaccinated, have to stay home in isolation if a family member becomes infected with the coronavirus. A vaccinated close contact may open a certificate for sick leave, if necessary.
• We recommend cancelling bigger parties and postpone more populous gatherings. The infection risk can be reduced with rapid testing. Read more about self-testing from the web page of the Health Board.
• If you have not been vaccinated yet, give your close ones a gift and get vaccinated! If you have already been vaccinated but more than three months have passed since the course, get a third dose. With the Janssen vaccine, a booster dose can even be done only two months after vaccination.
• Prefer spending time in open air to indoor gatherings. For instance, organize a nature hike with your friends.
• Think through your trips. If possible, use e-channels for errands -- most services are accessible through the internet.
• Plan your shopping for a time when there are fewer people in the stores. Wear a mask! It is possible to do your purchases online, contact free.
