RSV

RSV stands for Respiratory Syncytial Virus. This virus is highly contagious and often leads to colds or flu-like illnesses during the cold winter months. It infects the respiratory tract and causes symptoms such as a runny nose, cough, fever, fatigue, and often conjunctivitis. The most common complication, particularly in infants and young children, is inflammation of the lower respiratory tract. RSV infections are often indistinguishable from other flu-like illnesses or COVID-19 because the symptoms are very similar. If there are breathing difficulties, persistent high fever, or if a baby refuses to drink, medical attention should be sought immediately. RSV infections do not provide lasting immunity, so reinfections can occur. However, individuals without specific risk factors usually recover well.

For infants and young children

Whenever possible, avoid contact with people who have symptoms of a respiratory infection.

A new option is also available to provide targeted protection: passive immunization with the monoclonal antibody nirsevimab (Beyfortus®). This is recommended for all infants at the beginning of their first RSV season—ideally in the fall (October), or as early as possible for babies born during the winter months.

This immunization is not offered at our clinic. Please contact your pediatrician for further advice and administration. The cost is covered by mandatory health insurance.

For adults

The Federal Office of Public Health (FOPH) recommends a single RSV vaccination for adults ages 75 and older, as well as for adults ages 60 and older who have an increased risk of severe RSV disease.

Two RSV vaccines are currently available in Switzerland: Arexvy® and Abrysvo®. These vaccinations are currently not covered by mandatory health insurance, even when recommended based on age or risk factors.

Abrysvo® is also approved for use during pregnancy, between 32 and 36 weeks. This allows the mother to pass protective antibodies to the baby, helping protect the newborn during the first months of life. In this case, mandatory health insurance covers the cost if the expected delivery date falls within the winter months.

Vaccinating close contacts alone does not provide sufficient protection for infants. Effective protection requires either passive immunization with monoclonal antibodies or vaccination during pregnancy.

Our clinic does not offer RSV immunization for infants or pregnant patients. However, we do offer RSV vaccination with Arexvy® for adults ages 75 and older, or ages 60 and older with risk factors, who wish to be vaccinated.
