While vaccination is effective in resisting a new rise in coronavirus cases, “breakthrough infection” is possible even in vaccinated people.
Many countries today report an increase the incidence of coronavirus infection – its spread is believed to be facilitated by sub-variants of the Omicron strain BA.4 and BA.5. In the UK, according to the latest data from the ZOE Covid app, more than 350,000 people are on average infected daily.
At the same time, experts state that even in people with partial immunity from a previous infection or vaccination, a “breakthrough infection” is possible. That is, those who have already been ill or have been fully vaccinated can also get sick.
The ZOE Covid project identified seven signs of “breakthrough infection” in vaccinated people.
- Rhinitis.
- Cough.
- Sore throat.
- Fever.
- Headaches.
- Muscle pains.
- Fatigue.
Also experts note that in most cases of recurrent diseases today, people do not develop serious conditions, the infection is transferred quite easily – especially when compared with how people got sick at the beginning of the pandemic, when no one had immunity.

Meanwhile, the head of the World Health Organization (WHO), Tedros Adhanom Ghebreyesus, said that Omicron sub-options continue to cause new waves of hospitalizations and deaths around the world. The WHO also believes that the mask regime is becoming relevant again.
