WHO Updates Flu Vaccine Guide for Northern Hemisphere and Praises Denmark for Eliminating Mother-to-Child HIV and Syphilis

The World Health Organization (WHO) has announced updated recommendations for the composition of influenza vaccines that will be used in the 2026-2027 northern hemisphere season. These updates, based on global influenza surveillance data, aim to ensure that the vaccines match the influenza virus strains expected to circulate widely, offering the best protection against severe illness and deaths from the flu.

Each year, WHO brings together experts from its Global Influenza Surveillance and Response System (GISRS) to analyze recent data on circulating flu viruses. Because influenza viruses constantly change, these consultations — held twice annually — help guide national vaccine makers and regulators in selecting strains most likely to be encountered in the coming season.

For the upcoming season, WHO recommended specific influenza A and B virus strains for both traditional egg-based vaccines and newer technologies, including cell culture and recombinant vaccines. These recommendations help ensure that vaccines are effective and widely protective as people prepare for another flu season.

Denmark’s Major Public Health Achievement

In another significant health development, Denmark has become the first country in the European Union recognized by the WHO for eliminating mother-to-child transmission of HIV and syphilis. This means that the country has consistently met international targets over several years for prenatal testing, treatment, and prevention — ensuring that babies are born free of these infections.

To achieve this certification, Denmark maintained high coverage of prenatal screening and treatment for HIV and syphilis between 2021 and 2024, keeping new infant infections well below international thresholds. The achievement reflects the strength of Denmark’s universal health system, robust data systems, and rights-based health services that reach virtually every pregnant woman.

Dr. Tedros Adhanom Ghebreyesus, WHO Director-General, called the accomplishment a “major public health achievement”, noting that it demonstrates what is possible when political commitment, integrated maternal care, and consistent investment come together.

Global Implications and Future Goals

Both updates — the influenza vaccine guidance and Denmark’s certification — illustrate the ongoing efforts by global health leaders to prevent disease and protect communities.

• Seasonal flu preparedness is crucial in lowering the burden of respiratory illness, hospitalizations, and deaths each year, especially among older adults, young children, and people with chronic conditions.

• Elimination of mother-to-child transmission of HIV and syphilis sets a standard for other countries working to protect mothers and babies from life-changing infections. It also signals momentum toward broader goals, such as eventually including elimination of hepatitis B from mother-to-child transmission. 

Both developments highlight the role of strong health systems, global cooperation, and evidence-based public health policies in improving health outcomes around the world.
