Had a further reply to my now amended question.
I would probably ask the clinician when you receive the jab. The trials for Pfizer jab talk of a 95% reduction one week after 2nd dose given but obviously early days with trials etc. Oxford vaccine may be different.
Fair point early days with trials.
Before I read this I was in Sainsburys which has an in house pharmacy. Nobody waiting so thought I'd ask the pharmacist.
Essentially he said vaccines are usually effective after two weeks but not really enough info on the Covid subject and suggested 2 - 3 weeks.
Interestingly he said he had Covid in October and was tested (don't know when) for antibodies and returned a low count.
And that is the end of todays lesson.
The scientists/medics are finding out more as we go down the time trajectory.
As a doctor with a Phd in BS, I offer the following for consideration...
My take on the antibodies is why
wouldn't they eventually go down to a low level after you've recovered from covid, or from any other virus for that matter?
I would speculate that antibodies only remain high while your body is still fighting the infection, and fade away as you recover?
Maybe it could turn out that there is a correlation between long-covid and the amount of antibodies on your system?
At first they were saying that antibodies didn't persist for very long after people contracted and recovered from covid, and that seemed to be some cause for concern. Don't know
why it was a cause for concern, but it was chucked in as a throwaway line in various news reports over the last few months.
More recently there have been reports that in some instances the antibodies were lasting up to six months or more.
My friend, who has had
serious long covid, strongly tested positive for antibodies
9 months after contracting the virus in January 2020.
Explain that one.... anyone?
Anyway, the only thing I reckon we need to be bothered about is that the vaccines are shaping up to be:
a) pretty good at stopping onward transmission
b) pretty good at preventing serious illness and death, if you are unlucky enough to contract covid in the future.
That's more than sufficient good news for me not to lose any sleep over the matter
