AstraZeneca offers no protection against Omicron after 100 days

 

By Cod Satrusayang

 

A new report from the United Kingdom this past weekend suggests that two doses of AstraZeneca shots offers no protection against the Omicron variant of the virus.

 

The UK said it will make booster shots available to all of its residents over 18 years of age as the Omicron variant of Covid-19 spreads rapidly within the country.

 

Boris Johnson, in a speech late Sunday, urged the British public to get jabbed again to help stem the rising tide of the new variant first described in South Africa.

The full report is here in pdf format and its from the UK Health Security Agency Agency https://assets.publishing.service.gov.uk/government/uploads/system/uploads/attachment_data/file/1040076/Technical_Briefing_31.pdf

 

An Epidemiologist who works for them gave this twitter thread on it, I've just included a few snippets but it gives a clear explanation on the findings in the report if you go to the link read it all:

 

VACCINE EFFECTIVENESS (symptomatic infection) *caveat: early estimates* Real-world surveillance data shows a significant reduction in VE for Omicron vs Delta * 2x AZ, VE is ZERO * 2x Pfizer, VE is ~30% BUT! Boosters increase VE to 70-75% (Pfizer, in the 1st month)

 

Interpret VE data with caution due to low numbers & some residual uncontrolled biases. It is too early to measure protection against severe disease, but with earlier variants protection against hospitalisation & death has been largely preserved. All hoping this holds true

 

The VE drop off is much greater than we saw with Delta, and suggests a level of immune evasion that could result in a surge in 'breakthrough' infections. Good news is that boosters appear to mitigate much of that loss in VE, taking VE back to pre-booster levels

It still offers considerable T cell protection.  I think that's going to be the important thing in the future. We can't go on pumping people full of antibodies.

Get a booster, and hope that Omicron passes before your 100 days are up. 

[Jingthing]

So how exactly will expats get access to these boosters after three months?????

I've been looking and have found no program yet for those of us that had 2 AZ jabs.

[brewsterbudgen]

2 doses of AZ might not offer much (if any) protection against getting infected with Omicron, but it still offers protection against hospitalisation and death.

This is what they said on that:

Best will be to each to perhaps consider going back to their native countries and get the boosters there as getting boosters in Thailand seems to be a hit and miss game...

Reserve a Moderna booster vaccination at a private hospital?

 

Or get them free at Bang Sue railway station and a few other places in Bangkok.

Jinting - I heard this from a Friend the other day :-

 

"I had my third jab at Central last Tuesday. I had my second, Astra, in August. My wife and I walked in around midday. I showed the certificate from my previous jabs and my passport at the registration desk. In the vaccination hall I was offered Astra or Pfizer, I chose Pfizer. A fairly simple and efficient process."

 

Have a look around - a Pfizer booster would be ideal after 2 x AZ. Good luck

How has it been established that AZ will not be effective after 100 days against a variant that has been identified for much less than 100 days?

Hopefully.

Not proven yet.

Did they have TWO AZ jabs before?!?

 

Makes a big difference!

 

There has been a formal program for people that had Sino then AZ.

 

As yet I have seen no such program that includes people that had two AZ.

It appears that it has as far as the protection against getting imfected part of it.

I was looking before at a 6 month time frame. It seems Moderna is very scarce and when supplies appear they sell out instantly.

 

I want Pfizer anyway. As the government is now saying those with 2 AZ need a boost in 3 months not 6 they really need to back that up with formal national access.

Obviously.

They look at Omicron-AZ breakthrough cases now in the UK, and how long ago did they get their AZ shot. There is very little AZ data in the last 100 days.  Above 100 days, AZ shows very low effectiveness, about 5.9%.  That's why they mention 100 days.

Moderna isn't being sold directly to the public, you have to join a waiting list.

 

Upcountry, in the private hospitals, there are many people selling their Moderna rights. ????

It was being sold directly to the public with the limited stocks they had, Bumrungrad International Hospital Bangkok were selling it at 2 shots 3,300 or 1 shot at 1,650. For those that paid for it then decided they didn't need/want it they could not get a refund but they could transfer it to somebody else. I just paid one of those people the selling price for a 1 one shot dose, confirmed it with Bumrungrad and now have an appointment at a private clinic to receive it on the 22nd Dec here in Phuket as a booster shot for me.

Precisely, they paid a deposit for it and went on a waiting list. They didn't walk in, pay their money and get inoculated straight away. ????

They paid the full amount actually and yes it was direct to the public

[Chris.B]

A deposit can be the full amount as in this case.

 

And it wasn't direct, i.e. face to face, with the public.

Another "suggests" post. Given the first sample was on 9th November ( according to a site found with google https://www.cnbc.com/2021/12/02/where-did-omicron-covid-variant-come-from-and-where-is-it-circulating.html ) how can anyone state with certainty that it doesn't last past 100 days?

 

Seems like more fearmongering to me.

I've been in country for just over 6 months, entered with 2 AZ vaccines administered in Australia and get an AZ booster tomorrow in Ratchaburi from the local hospital with my passport and my wife's house (blue) book

 

No charge

Too soon to know with certainty.

Went to the vaccination centre associated with the local hospital on Thursday 09 Dec and asked if I could get AZ booster. Was told to come back on the 14,15 or 16 Dec for a booster no appointment required
