In recent times, Hamburg, Germany, has witnessed a significant increase in Haemophilus influenzae Type b (Hib) infections, particularly among adults with risk factors such as drug use and homelessness. This alarming trend has prompted the Robert Koch Institute (RKI) and the Standing Committee on Vaccination (STIKO) to update their vaccination recommendations for adults.
Since late 2024, Hamburg has reported at least 15 invasive Hib cases in adults, with 3 fatalities by July 28, 2025. These infections mainly affect adults who use drugs or who are homeless, suggesting these populations are at elevated risk.
In response to this outbreak, STIKO's 2025 guidance, as summarized in the RKI Epidemiological Bulletin (August 7, 2025), emphasizes the urgency of Hib vaccination for adults with these risk factors who live in or have contact in Hamburg or similar environments. The aim is to prevent further severe infections.
It is important to note that for the general adult population without these specific risks, routine Hib vaccination is typically not recommended, as invasive Hib disease is very rare in healthy adults. However, adults belonging to these high-risk groups are now recommended to receive Hib vaccination to protect against the rare but potentially life-threatening Hib disease.
Hib vaccine coverage data indicate strong childhood vaccination programs in Germany, but adult vaccination is focused on risk groups to contain outbreaks. The city of Hamburg is offering vaccinations in two drug consumption rooms to reach as many people as possible from the named risk group.
While a Hib infection is usually harmless in healthy people, it can cause serious complications such as pneumonia, meningitis, or sepsis in people with weakened immune systems. The RKI emphasizes that there is no cause for concern for healthy people. However, they also emphasize that there is an immunization recommendation for adults with certain immune deficiency diseases.
The number of Hib cases in Germany has increased in 2023, 2024, and up to July 20th of this year. This trend is not unique to Germany, as the number of measles cases is also increasing worldwide. However, invasive disease in healthy children over five years old is rarely seen, according to the RKI.
In conclusion, the updated vaccination recommendation is to vaccinate adults at increased risk (drug users, homeless individuals) in Hamburg and similar settings. Healthy adults without risk factors are not routinely targeted for Hib vaccination despite the outbreak. It is crucial for individuals within the risk groups to take advantage of the vaccination programs offered to protect themselves from this potentially life-threatening disease.

- Science plays a significant role in understanding and mitigating the risks associated with medical conditions like Hib infections.
- Mental health is equally important, and mental health issues can often be linked to chronic diseases and overall well-being.
- Indeed, heart disease, cancer, respiratory conditions, digestive-health problems, eye-health issues, hearing difficulties, and neurological disorders have all been linked to mental health.
- Fitness and exercise, a key aspect of health and wellness, can help manage weight, improve cardiovascular health, boost mood, and enhance cognitive function.
- Sexual health is another vital component of overall health and wellness, and therapies and treatments are available to address various sexual health concerns.
- Proper nutrition and skin care are essential for maintaining good health as one ages, as well as maintaining womens' and mens' health.
- Parenting can also be a stressful time, and it is crucial to focus on mental health and build a support system.
- Climate change can exacerbate existing health conditions, such as respiratory conditions and skin conditions, making it a critical issue in environmental science.
- Finance plays a role in accessing healthcare services and managing costs related to medical conditions, chronic diseases, and therapies and treatments.
- Wealth management, including caring for cars, homes, and personal finances, and investing wisely can help secure a stable future, which is crucial for overall well-being.
- Cybersecurity is another significant concern in today's digital age, as threats to data and cloud computing can impact various aspects of lifestyle, including finance, relationships, and entertainment.
