Coronavirus outbreak

[Slick]

I suppose it will also depend on the individual, protection percentage will be the population average which is irrelevant to any individual .

Its a good question though. 👍

NHS are offering booster doses 2 months after last vaccine for those most at risk, I think that if the protection was 75% after 2 months this would not be the case.

I thought for omnicron the best case scenario was 75% ???????

Which isn't bad as a vaccine - but there's so much about.

Someone I have spoken to senior in a local nhs trust. Expecting a different profile. Much lower icu requirement, much milder symptoms, but a huge influx will be needing to be processed in and out of hospital. Less about critical care but more of being overwhelmed with less serious patients and getting them in and then out.

FTFY - though maybe there's "so much all over" it should be called 'omnicron'.
The pre-print of a study (LSHTM 11 Dec) used these percentages (image below, just AZ1&2andmRNA for clarity), The only one I think is really pessimistic is the transmission one, where they use 37% protection (other models use 50%: 37% produces more scary (and therefore newsworthy) figures) and halves it for 'waning'.

Table 1. Vaccine efficacy assumptions. 1 = one dose; 2 = two doses; BL = booster dose, low booster
efficacy scenario; BH = booster dose, high booster efficacy scenario; W = waned from vaccine protection

Fourth dose?
Twelve months after your first one.

I think we are heading for annual doses as for flu!

Talking to two today who have dates for their fourth jab, not booster, in March.

My older sister has one coming up - she is immuno-compromised after chemo-therapy.

Hope she'll be okay.

Hopefully she won't have THAT problem to deal with too. Unfortunately, her other health problems are only going to get worse and there is no hope with them.

It wouldn't surprise me if it were every 6 months for the vulnerable and over 50s.

Sorry to see that last part.
A case of foot in mouth here

I was thinking more of the side effects of the jab.

No, I know what you meant - no harm done. The last thing she needs is a dose of Covid so that extra booster is a good idea for her.

I only discovered this by chance yesterday. The NHS makes a distinction between a third dose and the booster we are all being offered.

I was booking my son's booster yesterday and there was a statement on the lines of "if you are booking your third dose you must bring a GP letter confirming you are clinically vulnerable and qualify for a third dose.'

What the difference is I have no idea but it was a very clear distinction.

What the difference is I have no idea but it was a very clear distinction.

A third dose is no different to the first or second dose in terms of the volume of vaccine injected.

The booster dose is ~ half the volume of a standard dose and will be an mRNA vaccine (Pfizer of Mederna).
