Level of protection after AZ plus Pfizer Booster

[eggman007]

Does anyone have any information on this?

The only information I've read is:

2 x Pfizer = 30%
2 x AZ = 0%
3 x Pfizer = 75%

I vaguely remember seeing something like 70% (or thereabouts). Slightly higher after having all Pfizer.

Thanks Blabla, although it does seem odd how a single booster can take us from 0% to 70%

I'm 2x AZ + Pfizer and I believe it's about 70%

I'm not sure 2x AZ is absolutely 0 but I can't find the source to back it up.

I assume it’s because the antibodies have worn off. Mine had as I’ve just had covid - second dose was end of July.
Are they now realising that AZ wasn’t as effective as Pfizer?

I think it just said on sky
2 Astra Zeneca 30 percent
2 Astra Zeneca and 1 Pfizer 70 percent
3 Pfizer 75 percent

TokyoSushi, the 'close to zero' figure for AZ has been taken from UKHSA data. Here is a link referencing it:

Oh, ok Jesus, those figures sound more reassuring. Will have a look.

What about J&J? It’s only one dose .. anyone knows?
