How does a vaccine work?
A vaccine works by mimicking a natural infection. A vaccine not only induces an immune response to protect people from any future COVID-19 infections, but also helps build herd immunity quickly to end the pandemic. Herd immunity occurs when a sufficient percentage of the population becomes immune to a disease, reducing the chances of the disease spreading from person to person. The good news is that the SARS-CoV-2 virus has been fairly stable, increasing the viability of the vaccine.

UK Health Secretary Sajid Javid said: “The Red List and Quarantine System is critical to protecting our borders and, as we have said, we will not hesitate to take action by adding countries to the Red List.”

If they test positive they will only need to take an post-arrival test and a confirmatory free PCR test.
