Early #vaccination of previously uninfected children before their first #SARSCoV2 exposure could potentially strengthen population immunity resilience against future variants.”

In den #USA empfiehlt die #CDC nun auch einen zweiten #BA4/5-Booster für Risikogruppen. In #Deutschland lässt man es lieber drauf ankommen nach dem Motto: „Es ist vorbei!“

"Protection against XBB reinfection conferred by a previous omicron infection with vaccination was lower and waned faster than protection against BA.4 or BA.5 reinfection, which is indicative of the greater immune evasiveness of the XBB sublineage"

Ich habe eine schwere Diabetes Typ 2 und einen BMI über 40 und muss JEDESMAL über den Booster mit dem impfarzt diskutieren und auf die #impfung bestehen.. das war so beim zweiten Booster und auch eben gerade bei der Impfung gegen #BA4 #BA5. SCH... #STIKO. @minkorrekt @HOAXILLA

Mal impfen wollte, ging es nun endlich problemlos im #Impfzentrum #Bremen. Das ausschlaggebende Kriterium für war letztlich nur - 6 Monate Abstand zur vorherigen Impfung, sonst nichts (3 Monate zur Infektion wenn ich es richtig verstanden habe, aber da bin ich nicht sicher da nicht betroffen). #CovidIsNotOver #ImpfenSchützt #bivalent #BA4 #BA5 #Biontech #Moderna #ImpftDieKinder #FünfteImpfung #Booster
