Can you get covid after one dose of AstraZeneca?

[GreenFairyHouse]

Has anyone here got one dose of the AstraZeneca and went on to get covid?

If so we're you sick or ill.

My mother is late 60s and she got one dose of AstraZeneca. We are not in the UK so our vaccine rollout is not as quick as the UK.

She's only a week from her first dose of vaccine.

My understanding is that is takes a few weeks for the vaccine to take hold or it take up to three weeks for the vaccine to offer some protection against covid with more protection against the second dose.

She's not behaving as if she's bulletproof against covid and social distancing is gone out the window with her. She's not even meeting with her friends or anyone she can trust. She gets lifts from what I can only describe as the local village idiots. One of them said before he doesn't believe in covid, another recommended for me not to get the vaccine when it comes because its bad for you, another will be guaranteed to find the back door of a pub open or a shebeen. She's putting herself at risk by giving an ounce of trust towards these people that they will do the right thing and isolate themselves if they feel unwell. Just last week I was out for a walk and I met a local man on his bicycle and he was visably sick with a chesty cough. He said he woke up with a fever and a flu. I know flu is low in communities now and I think it was probably covid and he never isolated.

My mother took a lift this morning from a man and there was no need for it. The weather was lovely. There's no knowing where that man was or who he had in his car before her. I'm fuming now because she is behaving as if she is bulletproof.

I read from an online forum that someone got covid after one dose of vaccine. I don't know if that is true for mumsnetters.

Yes of course you can. You can get covid after both doses of any vaccine. But the chances are greatly reduced. But NOT 0.

How do people not understand this??

You don’t know if it’s true for Mumsnetters? What do you mean? It’s the same for mumsnetters as for the rest of the population.
Which is that yes, you can get Covid after a single dose of the AZ vaccine.

Of course you can! You can get Covid after 2 doses (although the infection is likely to be mild)
She is not protected a week into one jab

Yes of course it’s possible because a single dose of the vaccine does not give you full protection. In fact both doses won’t give you 100% cover but the hope is that if you do fall ill it will help lessen the severity.

That was my understanding too, that she's not protected from the vaccine jet but she thinks she is now bulletproof against covid.

You can get Covid after 2 doses of any vaccine.

They are preventive, not cures.

If they stop someone from getting seriously ill or dying, they are doing their job.

Yes.

MrsH is correct.

That's what happened in Chile. Everyone thoguht they were protected after one dose & so they all went out & partied, now have very high rates.

I had Pfizer in December. Had Covid early February. I was in bed for 2.5 weeks.
Had 2nd Pfizer 30 days after my positive PCR. I was ill for a day .

I had to tell my parents several times that they are not immune straight away. I told them you have some immunity after three weeks but I would still be careful. I hope they got the message.

Didn't they use a less effective vaccine as well?

Did you post here before a while ago complaining your mum was going into town on a bus and generally doing high risk things you disagreed with at the time ?

If it was you, it sounds like your mum just does what she wants and won't really listen. My mum is like this. You can't do much, but tell her she's not yet protected until three weeks after the first dose- that's when they say some form of protection kicks in. But of course, still not 100 percent.

For what it's worth, I worried about my mum so much and had fight after fight with her about what she was doing etc. But I gave up. They are their own people and will do what they want. Mum got covid in the end, as she was literally gallivanting around the place just seeing loads and loads of people. She was ok, mild case- I was happy, but she thinks it proves her case that it's just a cold/ flu.

It takes 22 days to build up immunity start the first dose. After that protection against covid isn't a certainty but it is much improved. Perhaps you could just give her an expectation of the time.

Didn't they use a less effective vaccine as well?
I think that's what they thought to start with but it was mostly in the first week after vaccination I believe.

@PinkSparklyPussyCat - yes, they used Sinovac which they are now thinking ain’t so good, basically very little protection after one dose. They have also used Pfizer but predominantly Sinovac.

Whereas we know Pfizer & AZ provides really good protection after one jab (3 weeks post vaccine) & the second jab is booster.

Vaccines don't stop you getting infected AT ALL!

But if you have immunity, either from a prior case of covid, or a vaccine, then your immune system will be much faster and more efficient at getting rid of the infection. But it takes time to develop the immunity. There's data to suggest that the first week following the first jab, you're actually MORE likely to become seriously ill if you contract covid.

By the end of week 2, your chance of developing symptomatic covid falls by 2/3 (i.e. your immune system is able to deal with it BEFORE symptoms have time to show).

My Auntie caught it ten days after first dose Pfizer, household mixing at Xmas. All four people who met had it, she felt awful but not as bad as her DS, DDIL and DH who ended up being hospitalised and still hasn't fully recovered.
