How likely to catch covid from child after one Pfizer vaccine?

[TheVolturi]

Dc tested positive today, has what seems like a bad cold but fine apart from that. I have only had one Pfizer vaccine 3 weeks ago. Getting a bit worried that I am going to be very unwell!
We are keeping all windows open and dc is spending time in bedroom unless having fresh air in the garden, but at 7 it's too young to fully isolate!

Current understanding is that one dose is only 30% effective against the Indian variant.

That’s for AZ. The OP has had Pfizer which is more effective after 1 dose. At 3 weeks with Pfizer I think your chances of escaping symptomatic infection are probably as good as they are going to get from 1 dose.

3 weeks is a very good time for the vaccine to kick in.

I’d avoid anyone sleeping in the same room with them. Keep 2 windows open if possible in each room (for through draught - much better than one). If you’ve a HEPA air filter use it.

Get him to use a separate toilet if possible, and you all wash hands but this isn’t the highest risk. Surfaces is very low risk but might as well minimise. First few days are the most infectious so be especially careful then.

You should be OK.

I assume DH will be WFH at the moment?

Of all the people I know who've had covid, including myself, none passed the virus on to other household members, none. It doesn't appear to be quite as infectious as we're lead to believe, either that or many people already have immunity as I've seen many others say the same thing about household members not contracting the virus. As for sleeping arrangements, I don't think it matters, you're sharing the same air when awake, being asleep won't make any difference.

Yes dh is working from home now.

This has been my experience too. One of my DCs is currently isolating for the third time (the whole of half term ) and on each occasion no one else in the class has caught it.

My sister failed to pass it on to anyone in her household despite not being able to isolate as her DCs are young and need her. I tested positive for antibodies last summer so assume the virus I had in jan 20 was Covid. No one else in my house got sick.

It's odd because when it's a cold or a sickness bug everyone tends to get it.

I slept in the same bed as my husband who tested positive back in December. I never caught it. I don't think it is a given that you would anyway. Agree with previous poster that if you are breathing the same air during the day the night makes no difference

I caught Covid from DS after 2 AZ, second 2 months earlier. I was fine though, just like a bad cold.

No, Pfizer is also only around 33% effective after one dose. Please do to research as saying otherwise is incorrect and will offer people false reassurance. I first heard that it is only 33% effective on the radio about a week ago and it’s been in numerous news articles ever since... this being one of them (the very first that pops up on Google when you ask how effective Pfizer is after one dose against the Indian variant). Note: you need to read the whole article as the first paragraph refers to effectiveness after 2 doses before later discussing one dose: www.google.co.uk/amp/s/www.independent.co.uk/news/health/covid-vaccine-indian-variant-dose-b1856312.html%3famp

It depends - most transmission is from ‘super spreaders’ and we have no idea who is going to be a super spreader. These are people who get covid and pass it on to a large amount of people because they ‘give off’ more virus.

It does matter how careful you are. This is why healthcare workers seem to have more severe covid because they have a bigger ‘viral load’ - as in around more of the virus for longer. So not sleeping in the same room would help. If you caught it you would be a bit less likely to have it as severely.

I think ds is likely a superspreader! He coughs without covering his mouth, despite being told repeatedly, wipes his nose with his hand and wipes it on his top and walks around like a slug touching every surface. If we escape this unscathed I will be amazed.

That’s for AZ. The OP has had Pfizer which is more effective after 1 dose. At 3 weeks with Pfizer I think your chances of escaping symptomatic infection are probably as good as they are going to get from 1 dose.

No, it’s for Pfizer. It’s 33% effective after 1 dose against the Indian variant. Slightly higher for the Kent variant, 50% for the original virus.

AZ has slightly lower efficiency after one dose.
