A residual risk remains: Vaccinated people can also become infected with corona, but then they often only show mild symptoms. Researchers have investigated what these are and how those affected should react.

There is a persistent myth about the corona vaccination: Vaccinated people can no longer be infected. But that’s wrong. Above all, the approved vaccines promise one thing: If infected with the coronavirus, those affected will not get sick, or at least not seriously. For example, the vaccines prevent 94 percent or more of the necessary admission to hospital.
But that also means that people who have been vaccinated can become infected. The Robert Koch Institute (RKI) announces that the “Covid-19 vaccines used in Germany prevent SARS-CoV-2 infections (symptomatic and asymptomatic) to a considerable extent. The likelihood that a person will be positive for the PCR test despite having been fully vaccinated is already low, but not zero. “
Corona infection after vaccination: very rare, but possible
Scientists at King’s College in London took a closer look at this group of vaccinated people who got infected anyway. They evaluated data from over 1.1 million British people who were vaccinated between December 2020 and mid-May 2021. They found only 2,278 people who tested positive after their first vaccination (0.2 percent) and only 187 who received a positive test result after the second vaccination (0.03 percent).
It was analyzed which symptoms the infected people developed. It showed: All typical corona symptoms occurred less often in the vaccinated – with four exceptions. They were reported in roughly the same amount or even increased after vaccination plus infection.
These four symptoms suggest an infection
- Sneeze: This symptom actually occurred more frequently in the group of those who had been vaccinated than in those who had become infected without vaccination. People under the age of 60 had to sneeze 24 percent more often than those who were not vaccinated. It is not entirely clear whether other diseases such as allergies could also be involved here.
- Shortness of breath: In its extreme form, this symptom often leads to hospital admissions for people who have not yet received the protective spade. This symptom also occurs in people who have been vaccinated. But hospitalizations are not to be feared. Here, too, the researchers concede: Shortness of breath can also occur with other diseases. Nevertheless: if you have difficulty breathing, you should take a test.
- Earache: Unvaccinated infected people often complain of tinnitus (circulatory disorders in the ear). These are beeping or whistling noises or reduced hearing. In contrast, those who have been vaccinated are more likely to experience earache.
- Swollen lymph nodes: They are typical signs of an infection – whether with viruses or bacteria. Lymph nodes can be found on the neck, neck or armpit, for example. They do not necessarily have to indicate a corona infection, but are also often found in the group of those who have been vaccinated.
Vaccinated people should also be tested
The conclusion of the scientists: Vaccinated persons show with a high probability no symptoms after their Piks with an infection. However, if symptoms of the disease appear, these are far fewer and also milder than in unvaccinated people.
Nonetheless, those affected who, despite having been vaccinated, suspect they have been infected based on the criteria mentioned, should have themselves tested. Because they too could pass the virus on.
