>No other vaccine needed boosters.
I'm just going to take a look at my yellow vaccine pass. I got what's normally recommended in Germany plus additional vaxx against TBE and Hepatitis. I assume you're a German man in your 20s or 30s, so you can compare yourself to me in that regard.
Against diphtheria, tetanus, whooping cough and haemophilius influenzae type b I got combined vaccines 4 times in my first two years of life. I have received 3 boosters so far and a booster is recommended every ten years. If you don't get the booster and go to a hospital with a larger wound, they will give you a tetanus booster anyway.
Against polio I got vaxxed 3 times within the first two years of my life and received 2 boosters since then.
Against TBE I was vaxxed 3 times, received 1 booster already and boosters are recommended every five years.
The vaccine against the coronavirus was very similar to the way some of these have been given: Two shots in short order and then a third one half a year later. We simply don't yet know how many boosters are needed (we can talk in about what is meant by "needed", too) and the coronavirus mutates quickly, similar to the flu. People who get the flu shot get it every year.
So your premise
>No other vaccine needed boosters
is just completely wrong.
