Is the booster always Pfizer?
I was at my local hospital earlier as it happens. They've signs up everywhere telling people to wear masks and are still checking/handing them out at the entrance. I didn't see anyone without one. And there's hand sanitiser everywhere.That's just bollocks isn't it - I wouldn't even try to go into a hospital without a mask on.
Heard immunity has been discarded. The CDC have changed their tune. Was 70%, then 80% then 90%, now, oh well.
ONS are saying 90%+ of people in the UK have antibodies so we should have hit heard immunity by now. ONS stats
Clearly not there, I'm guessing never will be.
More likely just variations of opinion about what really counts as 'effective vaccine'.Has Sasaferrato's post time-travelled from 18 months ago
We had Pfizer first, then a Moderna booster.It should be a mRNA vaccine, so that or Moderna, but not AZ.
No, just the hope.Has Sasaferrato's post time-travelled from 18 months ago

Odd.Until we have an effective vaccine, this plague is going to grind on.
I would think that such a vaccine will be with us within a year.
Odd.
Remember that vaccines don't prevent infection , you do.
What your asking for is a more effective immune system.
Are you perfect, and therefore is your immune system? No. So what your asking for may or also may not be possible.
All this. And there is precedent for vaccines which need to be "topped up" - tetanus being one obvious example, not counting 'flu, which is more about the variety of strains of 'flu out there, and their tendency - like Covid - to mutate, and, at least in the case of 'flu viruses, "escape" the protection of the vaccine by failing to trigger an immune response.In which case, why is it possible for polio, smallpox and diphtheria?
I think you have the wrong end of the stick, vaccines enable the body to make antibodies, and to remember the intruder, so if it comes again, antibodies can be manufactured in quantity.
Measles infection generally gives lifelong immunity, you are also unlikely to have had the same cold twice. A lot of immunity is by exposure to things like the cold, societies which have not had contact with those illnesses are hit very hard if they are introduced.
To say vaccines don't prevent infection is not accurate, they don't in themselves, but the antibody stimulus they engender does.

It's odd how so many people think as if the whole world of vaccine development is something that only just happened...
The latter...Yep, tetanus, BCG, TABT... Yellow Fever however is now recognised as a one off. (one of or one off?)
The latter...
Since my stroke (TIA), I have those moments, too, nowTa. It's one of those ones, when you look at it, you think 'Is that right?'
I get those all the time,Ta. It's one of those ones, when you look at it, you think 'Is that right?'
A mutation of the Covid-19 Delta variant which has been found to be more infectious is now responsible for one in 10 Covid cases in England.
The latest results from a REACT-1 study by Imperial University found that the AY.4.2 variant, which is more infectious but less likely to cause symptoms, is growing at a rate of 2.8 per cent a day.
Tests carried out between 19 October and 5 November on more than 100,000 people in England showed that 11.8 per cent carried the variant.
However, the data showed only a third of those with the AY.4.2 variant had the common Covid symptoms of fever, persistent cough or a loss or change in taste or smell compared to 46 per cent of people with the original form of the Delta variant.
They were also less likely to show any other symptoms.
I'm going for my booster tomorrow. Can't bloody wait.
Getting mine today, quite efficiently called up by text
Made an appointment for my booster today - will be bang on 6 months after my last vac
