Health bosses in the Channel Islands have confirmed they will follow the UK in offering an alternative coronavirus vaccine to young people.
Anyone under 30 with no underlying health risks will be offered the Pfizer-BioNTech or Moderna jab.
It comes after some concerns that the Oxford AstraZeneca jab has been linked with a very small number of blood clots in younger people.
The Moderna vaccine is due to arrive in Jersey next week.
Jersey's government also said that the new guidance will not affect the longer term roll out of the vaccination programme for Phase 2 as appointments open to people aged 40-49.
The Oxford AstraZeneca vaccine is safe, effective and has already saved thousands of lives. As the MHRA and the JCVI have said, the benefits of the vaccine far outweigh the risks for the vast majority of adults. Everybody who has already had a first dose of the AstraZeneca vaccine should receive a second of the same brand, irrespective of age. When people are called, they should get their jab.
Data from the Medicines and Healthcare products Regulatory Agency (MHRA) suggests that all reported incidents of bloods clots have been associated with the first dose of the vaccine.
Islanders who've received their first Oxford-AstraZeneca vaccine, whether under or over 30 years old, need not be concerned and do not need to seek healthcare unless they have leg swelling, shortness of breath, pain in their chest or abdomen, bruising beyond the vaccination site or neurological symptoms such as prolonged headache or confusion, especially if occurring within 14 days of vaccination.
