Can anyone help me with the current requirements for covid testing ( 1x traveller not vaccinated, 1x fully vaccinated but only 6 days since 2nd jab, 1x traveller fully vaccinated) driving from UK (Eurotunnel) through France and final destination Spain. We are just driving through France with 1 night stop over. What tests do we need to get from UK to france and do we need more tests to get from France to Spain? Many thanks in advance.
