Until the scientists figure out exactly what the mutations are, we won't know either way. If the protein spikes are the same then we're ok. If that has changed then there may be problems. Work is being done even as we type.

Not as totally new ad the media are making out. The technology has been in Stage 1 and Stage 2 trials for years, but the storage and distribution costs meant it never progressed to stage 3. Obviously Covid has made those costs bearable.Sieper wrote: ↑04 Jan 2021, 18:10The vaccines are a totally new way of preventing getting a RNA (virus) based sickness.

Good thing you don't work for the NHS then as we'll all be getting the Oxford one. Indeed a friend of mine who is a GP tells me the NHS will not be ordering any more of the Pziser one, so the UK will be relying on the Oxford vaccine.Tommy Cookers wrote: ↑04 Jan 2021, 16:10agreed both the 'American' vaccines seem proven (by 'robust' tests) to reduce deaths by 90+% (actual body counts)henry wrote: ↑03 Jan 2021, 21:29Like @Big Tea I don’t think a vaccine is a sliver bullet.

.....
but the 'UK-Oxford' vaccine (more conservative design - and tests?) just introduced seems unproven at reducing deaths
eg for the conveniently changed-dosage tests the subject group wasn't age-representative
the so-called 'full protection' of some widely-used vaccines can be as low as 50%
(ie I wouldn't rely on the 'Oxford' to save me - so wouldn't spectate at a race in 2021 even if it was allowed)
please if you can tell me/show me how I'm wrong
btw remember there was a GP season in 1939 and in 1940
Thanks for the info, also, I realize these weren’t started from scratch, but still, a decade ago we would have had no options at all. Now the normal economic restrictions mean nothing. You would hope on a bit more foresight but the way politics are executed these days make me fearfull.adrianjordan wrote: ↑05 Jan 2021, 01:52Not as totally new ad the media are making out.

Of course the 'beat down' and questioning the Oxford vaccine has been getting internationally- particularly in the US- is partly to do with other countries protecting their own financial interests and promoting their own vaccines. It's a bad look if they have to buy in or defer to a cheaper, easier to store and similarly effective vaccine from another country rather than use their own, even it if ends up costing ten times the amount- and we are talking billions of dollars difference here. Politics of course will always rear it's head, even with things like this.adrianjordan wrote: ↑05 Jan 2021, 01:55Good thing you don't work for the NHS then as we'll all be getting the Oxford one.

FWIW my friend understands the science a whole lot more than me and thinks the Oxford one is preferable.
It's also important to remember that the effectiveness rates we're seeing talked about for these vaccines a far better than, for example, the seasonal flu jab.
(in a very shortened form) with the AZ protection begins from 6 days after jab takes 20 days for full effect.
Just to be sure, this second paragraph was independent of your first - they were not vaccinated or anything like that. It was purely a reinfection / immunity study?
Was the sample positive in both cases or just showed antibodies? As I posted above, some showed symptoms but did not have the 'actual' virus, just the antibodies from previous infection?nzjrs wrote: ↑05 Jan 2021, 16:37Just to be sure, this second paragraph was independent of your first - they were not vaccinated or anything like that.

Fwiw a good friend of mine, 32yr old has had covid twice, both times decently symptomatic and feeling bad. Both cases 3 months separate from one another. Test confirmed both times. But I agree with you he must be the outlier now we have enough data.
Both times PCR positive, with a negative PCR in between too. He's a molecular biologist PhD and was very annoyed he didn't keep a sample from the first infection to sequence it (and compare with the second). He was quite sick/symptomatic both times too.
Thats a concern
We have had 2 staff members that I know of test positive again after the original infection was over 6 months ago and they have had negative PCR tests in the interim.Big Tea wrote: ↑05 Jan 2021, 16:05(in a very shortened form) with the AZ protection begins from 6 days after jab takes 20 days for full effect.
Of the 44,000 test patents 0 people had to go to ICU after this time (2 in the pre 20 days) of having the FIRST jab
Other good news is a study in Newcastle followed 1100 NHS frontline staff who had Covid in the first wave.
None of them re contracted it. 120 reported covid like symptoms but none were covid.
