- It is unclear whether vaccination against influenza (flu) should generally be recommended for asthmatics. There is insufficient scientific evidence. Nevertheless, the experts generally agree that the annual flu vaccination is recommended.
- It is also unclear whether vaccination against pneumococci (pneumonia) should generally be recommended for asthmatics. Again, there is no scientific evidence of a benefit. The World Asthma Society (GINA) does not recommend vaccination, but the German STIKO (Standing Vaccination Commission of the Federal Republic of Germany) does.
