@catwomandoo You have missed out part of the guidance. it includes taking daily lateral flow tests.
@TooTiredForThis2 You do not need to isolate if you are over 18 and have had 2 jabs.
However, it is strongly advised [this is on the government info]
COVID-19 infection rates are very high and the Omicron variant is spreading rapidly. It is important that we all take steps to reduce the spread of COVID-19 infection in the community to save lives and protect the NHS.
If you have COVID-19 symptoms you should stay at home and self-isolate immediately. You should arrange to have a PCR test as soon as possible. If this PCR test result is positive, you must continue to self-isolate.
If you do not have COVID-19 symptoms, but you have a positive PCR test result, you must stay at home and self-isolate.
If you live in the same household as someone with COVID-19 you are at significantly higher risk of becoming infected yourself.
If you have been vaccinated with a COVID-19 vaccine, you are less likely to become severely ill if you catch COVID-19. You are also less likely to spread COVID-19 to other people, but it is still possible for this to happen. Therefore:
if you are aged 18 years 6 months or over and you are not fully vaccinated*, and you live in the same household as someone with COVID-19, you are legally required to stay at home and self-isolate
if you are fully vaccinated or aged under 18 years and 6 months, and you live in the same household as someone with COVID-19, you are not legally required to self-isolate.
However, you are strongly advised to take an LFD test every day for 7 days, and to self-isolate if any of these test results is positive
You are fully vaccinated 14 days after having received two doses of an approved vaccine (such as Pfizer/BioNTech, AstraZeneca or Moderna/Spikevax) or one dose of the single-dose Janssen vaccine.
LFD tests are very good at identifying people who have high levels of coronavirus and are most likely to pass on infection to others, even if you do not have symptoms.
