A GP trainee friend doing a video for her practice based on a morning's phone clinic (which she did from home cos she's awaiting PCR results):

1) If you have any symptoms including snotty nose, sore throat and significant headache you need a PCR as lateral flows are for screening asymptomatic people and are unreliable in symptomatic people.
2) If you have had Covid vaccinations you can STILL get Covid. It is a bit less likely and a lot less likely to be severe, but you can still contract and transmit it. As per above, if symptomatic, get a PCR (and stay away from others).
3) If you have had Covid before with or without jabs, you can still get Covid again, see (1) re PCR for symptoms.
Of course whether you can GET PCRs at the moment is in doubt, but I guess the trick is to keep trying.
While you may have Covid mildly, there is no guarantee that another person you could transmit it to would also be mildly ill. We don't have stats on likely Long Covid from Omicron and while it is "less severe for most people" it is so transmissible that high levels of it in the community correlate to high NHS demand.
I don't think we're at the "can ignore it" and don't think we'll get there until we've vaccinated more of the world and been sensible. I expect 2022 to be a repeat of 2021 and not to be Covid free.
