Meanwhile, the number of infected people worldwide has risen to more than 200 million people - and half of the population in Germany is fully vaccinated: At 54.5 percent, we are lagging behind the average of more than percent in the EU, but globally only 15 benefit. 2 percent from the injection syringes. Given these numbers, it seems strange that booster or booster vaccination is now being discussed, as if future events in the country depended on it, rather than on getting more vaccinations. As a hamstering dessert, before the starter is eaten and served at other tables - countries - at least. Or what about the bratwurst as a vaccination incentive?

If incidences increase because the delta variant of SARS-CoV-2 is more contagious, and there is also greater carelessness, this goes hand in hand with a higher risk for vulnerable groups, such as the elderly or transplant recipients, whom we want to protect. They depend on boosters when their immune response is already weak and Delta can hardly keep them in check. As for who this is concerned, one cannot say in general terms: The dynamics of the immune system is currently being researched; Perhaps it is all high-risk patients or only individual cases that doctors have to give a third shot out of care.

Nobody knows what protection is sufficient to stop an illness. Antibody titers drop, but after a complete vaccination, otherwise healthy people can trust that certain T cells will remember - and become active, thus preventing severe courses. "Vaccination breakthroughs" are to be expected more often at Delta, vaccinated persons can become carriers without becoming ill themselves, and the same could apply to Lambda. But it would be nonsensical to soon declare boosters a corona routine. That's going to take time. The mask, which is and will remain with us as a protective accessory for the time being, is different. All of us.
