The decision is made in the throat.
If the coronavirus can spread in the upper respiratory tract despite the vaccination, the viral load increases and with it the likelihood of infection, says Michael Hölscher, Director of the Tropical Institute at the Munich University Hospital, the SPIEGEL.
With every sneeze, every cough, every drop of breath, viruses could be thrown out of the throat and look for a new host.
So far it is clear that the first Covid-19 vaccine from Biontech and Pfizer to be approved in the EU can prevent diseases caused by the coronavirus.
However, it remains to be seen whether it will completely stop the virus in the throat before it makes its way into the body.
The question is also unresolved for the vaccine candidates from Moderna and AstraZeneca, who could make it to approval next.
Through vaccination for herd immunity?
However, there is no scientific negligence behind this, but rather prioritization.
Vaccines against other infections can also prevent disease, but not always the infection itself.
For the vaccinated, this is not necessarily crucial.
Because if they don't get sick, most of them will not feel the infection.
