From 10 September, all newborns in Sweden will be offered protective antibodies against RSV. Around 87 per cent of parents accepted last season. A preliminary analysis found about 82 per cent fewer hospitalised children under six months, although the Public Health Agency notes that a milder season also contributed.
What happened?
The previous programme covered babies born between 10 September 2025 and 17 May 2026, when that RSV season was considered over. Antibodies were given in maternity units after birth. The national compilation from clinics shows coverage of around 87 per cent.
Hospital care among children under six months fell by about 82 per cent compared with the previous season. Seven children in this age group needed intensive care, compared with 45 the season before. The agency describes the hospital analysis as preliminary.

Impact and significance
The Public Health Agency considers the protective antibodies the main reason for the reduction, while also noting that the season was milder, started late and peaked in March and early April. The entire change therefore cannot be attributed to a single factor.
RSV usually causes cold-like symptoms but can lead to breathing difficulties or pneumonia in infants. The youngest are most vulnerable because their lungs and immune systems are still developing. Antibodies are aimed mainly at newborns and, according to the agency, provide protection for about six months.
Background
Some older children with conditions placing them at high risk of severe RSV infection are also offered treatment. The Public Health Agency defines the risk groups, the Medical Products Agency has developed treatment recommendations, and the regions’ NT Council procured the medicine and provided implementation guidance.
The programme normally continues until the RSV season ends, usually in April or May. The precise offer for an individual child is determined within healthcare under current recommendations.
Latest update
The second national season begins on 10 September 2026. From 1 November, confirmed RSV cases become notifiable by healthcare providers, which is intended to improve monitoring. Parents with questions about the offer, risk groups or a child’s symptoms should contact maternity or paediatric healthcare and consult current authority information.
