Laut CDC: Will a COVID-19 vaccination protect me from getting sick with COVID-19?
Yes. COVID-19 vaccination works by teaching your immune system how to recognize and fight the virus that causes COVID-19, and this protects you from getting sick with COVID-19.
Also nach meiner Interpretation:
Selbstschutz, man kann (möglichst) nicht sich selbst mehr infizieren und krank werden, damit - wenn viele Geimpft sind - Herdenschutz erreicht.
Wenn ich nicht mehr selber erkranke, werde ich natürlich weniger infektiös sein als ohne Impfung.
"We suggest that COVID-19 vaccines are promising when they induce large quantities of high affinity neutralizing antibodies and only relatively low amounts of other antibodies and immune responses bearing the risk of disease enhancement. Targeted by most neutralizing antibodies, RBD may be the virus’ Achilles heel. However, it is still only partially possible to predict vaccine efficacy and safety [116]. It remains justified to pursue the development of multiple different vaccine types, also against other target antigens, possibly increasing the likelihood of success.
The large scale use of vaccines inducing neutralizing antibodies is the best option to maximize the percentage of the population with immunity to SARS-CoV-2. It is realistic to achieve herd immunity through vaccination, whereas broad natural infection appears too risky for humans and the economy, unless viral spread induces immunity in much larger fractions of the world’s population than currently known and expected, possibly in countries with less rigorous measures for avoiding viral spread. Due to the urgency, COVID-19 vaccination is given high priority."
