Greek infectious disease specialists have raised concerns over the country’s low vaccination rates, highlighting its impact on the spread of diseases and the emergence of localized outbreaks of influenza, meningitis, COVID-19, and pertussis among both adults and children.
This issue was highlighted during a press conference held by the Board of Directors of the Hellenic Society for Infectious Diseases on the occasion of the 24 Panhellenic Infectious Diseases Congress, which commenced on March 13.
Experts emphasized the particularly low vaccination rates among adults, pointing to alarmingly insufficient immunization coverage for diphtheria, tetanus, and pertussis, as well as hepatitis and other serious diseases, despite the availability of safe and effective vaccines.
The resurgence of old threats, once thought to be under control, has been a growing concern in the field of infectious diseases. Meningitis, the respiratory syncytial virus (RSV), and other infections have reemerged due to inadequate immunization coverage, stated Nikos Sipsas, President of Society for Infectious Diseases.
A particular focus was placed on the alarming rise in pertussis cases, particularly among infants. In 2023, Greece recorded just nine cases, whereas by December 2024, the number had surged to 438.
As noted, 15% of these cases involved infants under two months old. Pertussis in newborns can be fatal, with two infant deaths recorded in 2024, while at least three were admitted to neonatal intensive care units.
Pregnant women, who play a crucial role in protecting newborns through vaccination, also showed low immunization rates. A study conducted in two major Athens hospitals found that only 38% of surveyed pregnant women had received the diphtheria-tetanus-pertussis vaccine. The uptake was even lower for other vaccines recommended during pregnancy.
The situation is similarly concerning among the elderly, a group particularly vulnerable to severe influenza. Hospitals across the country have been overwhelmed with flu cases, primarily among senior citizens who should have been vaccinated.
While those over 65 are advised to receive enhanced flu vaccines, the majority opted for a standard, over-the-counter option, often administered too early in the season. Experts emphasized that in Greece, the optimal time for flu vaccination is November, not September, as many mistakenly believe.
The findings presented at the congress highlight the urgent need for increased public awareness and improved vaccination strategies.
