Chances of re infection with omicron

[Remoanercorona]

Can anyone point me towards some reliable data regarding the probability of catching omicron having had 2 vaccines plus booster plus having had a recent (last month) covid infection.
I feel pretty untouchable tbh and am hoping to go to a a concert next week but don’t want to jeopardise Christmas with visiting family.

Bumping as would also like to know!

Looks like I’m not the only one who can’t find anything!

I don’t know any specific data that answers your question but it has been reported that -

• Boosters increase immunity to omicron, and double vaccination only provides low levels of protection (especially AZ)
• prior infection with delta does not convey significant immunity to omicron (unlike it would for delta)
• immunity against any variant of covid incorporates a whole range of defences of which antibodies are just one line of defence. Eg T cells.
• people respond differently to vaccines and some fail to mount a sufficient immune response

So you have probably got as high levels of protection that you can. On the other hand there is a lot that is not yet understood, and many variations between individuals probably due to genetic factors, how they manage the illness once infected, viral load, etc etc.

@Remoanercorona - did you get the booster before or after you had Covid?

I've also been looking online, and struggling to find an answer.

I've had to vaccinations and Covid, so now wondering how soon to have the booster. Do I need it now or would it be best to leave it a few weeks while I have natural immunity, and then let the booster do it's job? That was my original plan, but now with omicron I'm not so sure

• Boosters increase immunity to omicron, and double vaccination only provides low levels of protection (especially AZ)
• prior infection with delta does not convey significant immunity to omicron (unlike it would for delta)

But why is the booster more effective than having had the delta variant?

Same here. I had Covid early November after 2 AZ (and just before 6 months point) and getting my booster tomorrow. I joked with my boss that I'll be glowing like the readybreak person with immunity, lol. The only information I could find has already been highlighted, basically reinfection from Delta, while it occurred was considered "rare" but reinfection with omicron is supposed to be quite significantly higher (can't remember exact figures). What they don't or can't tell you is reinfection after how long. Which I think is what most people would like to know, so are you likely to be reinfected one, two or three plus months post infection?

This is an important point when considering the under 18s, with the risk balance of reinfection and risk of myocarditis too. So they can't get a vaccine until 3 months post infection but are they likely to be reinfected before that time? Do they need the vaccine post infection?

One positive I read is reinfection tends to be milder which is something.

Another factor is that exposure to covid without infection (if youve had a vaccine). can further act as a natural booster

I had the booster 2 days before I got a positive lateral flow.
It was a very mild dose-headache, no smell or taste for a couple of days. That’s about it.

I've just heard Chris Smith in discussion on LBC, to paraphrase, you can't have too much vaccination.

It’s surely very unlikely to get it again within a few weeks whatever variant isn’t it?

What date is the gig?

Because of exponential spread there will be substantially more omicron around as time passes so the risk will be dramatically higher in a week (than it is today.

You are unlikely to catch delta again so soon.

You have more protection now against omicron than you had when you tested positive for delta because the booster has had time to get those antibodies surging.

But less protection than you had against delta. (70% or so now versus 90% or so then)

So you're 3x more likely to catch it on vaccine grounds and {exponential growth in infections} more likely to catch it because prevalence is so much higher than it was a month or so ago.

I have no idea if or how much previous delta infection helps you. A lot of stuff I have read discounts it because omicron has mutated into such a different beast.

The reason you can't find an answer is because there isn't enough data to have an answer.
