Okay so was wissen wir soweit oder was weiß ich soweit?
Wir haben die Studie¹ aus Israel mit Daten von mehr als 1 Million Menschen. Ein Artikel² in Nature zeigt uns diese Studie und sagt Zitat
The latest study evaluated 1.1 million Israelis over the age of 60 who had received their first two doses at least five months earlier. Twelve or more days after receiving a third jab, participants were about 19.5 times less likely to have severe COVID-19 than were people in the same age group who had received only two jabs and were studied during a similar time period.

In The Lancet ein Artikel³ sagt Zitat
Careful and public scrutiny of the evolving data will be needed to assure that decisions about boosting are informed by reliable science more than by politics. Even if boosting were eventually shown to decrease the medium-term risk of serious disease, current vaccine supplies could save more lives if used in previously unvaccinated populations than if used as boosters in vaccinated populations.
Boosting could be appropriate for some individuals in whom the primary vaccination, defined here as the original one-dose or two-dose series of each vaccine, might not have induced adequate protection.
The vaccines that are currently available are safe, effective, and save lives. The limited supply of these vaccines will save the most lives if made available to people who are at appreciable risk of serious disease and have not yet received any vaccine. Even if some gain can ultimately be obtained from boosting, it will not outweigh the benefits of providing initial protection to the unvaccinated. If vaccines are deployed where they would do the most good, they could hasten the end of the pandemic by inhibiting further evolution of variants.

Die STIKO-Empfehlung zur COVID-19-Impfung bei Personen mit Immundefizienz⁴ sagt Zitat
Eine serologische Antikörpertestung wird außer bei schwer immundefizienten Personen mit einer erwartbar stark verminderten Impfantwort nicht grundsätzlich empfohlen. Wie das Epidemiologische Bulletin 39/2021 ausführt, ist für Personen ohne ausreichenden Immunschutz weiterhin die Einhaltung von Abstands- und Hygieneregeln besonders wichtig und ihre Kontaktpersonen sollten unbedingt vollständig geimpft sein und im Umgang mit schwer immundefizienten Personen nicht auf einen medizinischen Mund-Nasen-Schutz verzichten.

Ich denke die Empfehlung ist okay und macht Sinn
