Efficacy of a Nasal Spray Containing Iota-Carrageenan in the Postexposure Prophylaxis of COVID-19 in Hospital Personnel.., 2021, Figueroa et al

@Sasha
I am unable to answer your question about sterilising vaccines but I would add that in a recent consultation with Dr Bansal, he advised that I should add in a specified nasal spray to use prophylactically in order to avoid covid as I extended my activities.This is on top of masks, distancing, etc.

I found this link to one of the components of the recommended nasal spray, Carageenan ( added).

 

Thank you for enquiring about this nasal spray @Sasha.

On looking at the link above , the results looked promising. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8493111/

"In this pilot study a nasal spray with I-C showed significant efficacy in preventing COVID-19 in health care workers managing patients with COVID-19 disease."

I shall be around people more than usual soon and will buy an extra bottle so that we don't run out. Have already stocked up on test kits, masks etc.

 

is it a brand you can buy in uk?

 

Yes. Will PM you.

 

If it was the Boots one I used I before I came down with Covid. It did take a while to develop and more than 4 days to return a positive Covid test which may be why?

 

me too pls

 

I too would like to know, please.

Would be interested to find out if something similar is available in Sweden, does anyone know?

 

In case of wider interest, Dr Bansal recommended a Carageenan spray. We have Boots Dual Defense nasal spray.

I found this link to sprays containing Carrageenan.

Sorry @mango. No further information.

 

I use Vicks First Defence Nasal spray but it doesn't appear to have Carrageenan in it. Perhaps I should switch to the Boots one. I tend to use it before I see people or go out (rare!) rather than on first sign of illness. Seems worth doing if it might make a difference.

 

For anyone who might be interested, this product is easily available in the Swedish online pharmacies:

Just had a look at the Boots Dual Defence Nasal Spray and it says it contains kappa-Carrageenan, as opposed to the iota-Carrageenan referred to in the research paper. Is that likely to make a difference? Is there a kappa-Carrageenan spray available in the UK?

 

I don't know @Sasha. If I can find the energy, I'll look out Dr B ansal's letter. May be this evening. I did a sleep study at weekend and am not recovered.

 

Mr B found the letter. Advises a carrageenan spray from Boots the chemist ( Dual Defence Nasal Spray) as this can reduce the ability of viruses to enter the body.

No more information I'm afraid. If you are really concerned, could you email Boots?

 

Thanks, @Binkie4 - and I hope you recover from your sleep study soon!

I came across an iota version available in the UK but it appears to also contain a dodgy chemical so I think I'll go for the Boots one, which otherwise contains just water.

 

No idea if this is linked to carrageenan spray.

 

Here's a link to that press item. It says:

It has only been tested on mice so far.
