Delays in deliveries, production bottlenecks, exports control, vaccine hesitancy and public feuds with pharmaceutical companies have muddled the first months of Europe's vaccination campaign against COVID-19.
The ECHR ruled last week that compulsory vaccination can be considered "necessary in a democratic society".
The court, which is based in Strasbourg, is the final interpreter of the European Convention on Human Rights and its jurisdiction covers all the 47 member states of the Council of Europe.
The verdict came in a case involving several families from the Czech Republic whose children had been refused admission to school because they had not been fully vaccinated against a panel of nine diseases, including poliomyelitis, hepatitis B and tetanus. A parent was fined for the failure to comply.
