Can anyone help we have just been to Iceland and had our results from out PCR tests. Everyone is negative accept my 12 year old son. My husband and I are fully vaccinated and my 14 year old has had his first vaccination and I cant work out if we all need to isolate or if my husband and I just need to LFT every day (we are doing this anyway). Any help would be appreciated if you have come across this situation please. 😊
