AZ vaccine - should we be revaccinated?

[mirandaspanda]

There have been a number of reports of AZ vaccine not being effective as the other vaccines - for example it doesn't provoke a good response in those with immunity issues and now it seems it's not at all effective against the Beta variant whereas Pfizer was highly effective.
I received AZ as I am sure did a large number of elderly and or CV people. If this population is completely unprotected against a variant - surely revaccination with an effective vaccine is required?

It never made sense to me that we gave AZ to our most vulnerable. I do hope they boost soon, plenty of options with surplus mRNAs, J&J, and Novavax soon (I hope).

There’s so little evidence on the safety of mixing vaccines that it’s rolling the dice all over again for those people. It’s really unfair.

I thought there was good data from trials about mixing? I'm sure I read a piece about AZ people being given Pfizer as a booster (and vice versa). I'll see if I can find it.

Yes! I didn't imagine it. Here it is:

Well apparently pzifer is disaaponting agaisnt delta?

Can we win??

Are people being given two different doses of the vaccine e.g. AZ and Pfizer in the UK? They are in Italy.

99% of all cases in this country are Delta. And it's effective against that so is still a really good vaccine.

I thought that by now we would have 6 or 7 vaccines available, but despite trials going on for the others, nothing has been decided. I expect unless another vaccine gets approval, AZ will be given as a booster from September to over 50’s.

I'm not really sure why you've posted that link?

The one I posted directly before you was based on an actual study.

There is an updated AZ vaccine to cover the beta variant. It’s currently in trials, and hopefully will be approved as a booster come the autumn.

No they are not.

If you ask your GP you can get different doses.

As a contribution? Or is that not allowed? The article discusses studies if you read it.

It’s MN not bloody Oxford University.

But it should be about data. Not opinions.

I’d stop listening to most of SAGE then….

My friend who works for AZ told me yesterday that they had put out a press release for an updated new version of the vaccine.

I've not seen anything anywhere about it.

Point being that it is now likely to not simply be a 3rd dose of the same thing but probably a new version.

Friend said AZ were claiming it had less side effects too.
