As far as they can tell you do get immunity after having COVID, however, after about 3 months it starts to tail off. But, there is some research to suggest that if you get it again it will be less severe.
At least one reported case has had it worse second time (in Vegas iirc where the person ended up in ICU) And mutations of the original virus can render any immunity through infection or a vaccine redundant.

Every year we have a top-up vaccination against flu based on what variants they think is likely to be prevalent - although flu is a family of viruses with similarities (H1N1, H5N1, etc). Bacteria is evolving resistance to antibiotics - MRSA. (I know bacteria are not viruses but those were just two obvious examples of a similar situation). There is the possibility that Covid could evolve a mutation that renders it immune to the vaccine - this possibility is potentially increased by increasing the time between the first and second shot - and also the number of people that are infected. The mutation can be one or two bits of the DNA/RNA or more - there are currently several thousand Covid-19 variants including the B117 and South African (501Y.V2) variants. These can each be different by 1-2 pieces of genetic code, which can then become many more. Most mutations are bad for the virus and it dies out, but some are good for the virus (and worse for us). B117 has 8 changes to the spike protein (and others elsewhere), 501Y.V2 has 9 in the spike. Scientists are concerned about the possibility. It might not happen, but all the major vaccines work in the same way (detecting the spike protein) so it is possible that a vaccine-resistant Covid-strain could put us all back to square one until other vaccine forms (based on antibodies or other) can be made to work. https://www.nature.com/articles/d41586-021-00031-0
Hi. I just wondered if anyone has seen anything in the plethora or cr4p/ facts that we get fed that outlines if a person can be totally immune to Covid-19. I’ve mentally categorised folk into 5 broad categories but have no idea if the following are sensible: 1/ covid immune. Does not even carry the virus 2/ asymptomatic. No ill effects but can carry and spread the virus 3/ mild symptoms. Feel a bit unwell, loss of taste etc. Carries the virus 4/ medium/severe symptoms. Unwell, not in need of hospitalisation. Carries the virus. 5/ severe/life threatening. Needs hospitalisation. Might just be how I try to visualise and deal with things. I don’t for one minute think this stuff isn’t real but it would Be nice (IMO) to try and understand risk/likelihood etc.
at the moment my understanding is everybody is in 2 to 5 there are no cases of anybody being found to be immune and not even able to carry it when you have the first jab it should eliminate level 5 probably lowering to 3 and with the second jab lowering to 2 but the jabs do not mean you can not carry the virus
Matt Hancock has just done a briefing and here is a warning from @paddysmad to any male wondering if they will take it or not
Wouldn’t read anything into that calculator. Based on 1 million vaccines a week but we know they’re aiming to get up to 2 million a week by end of January and then presumably to continue to expand it thereafter.
I'm not so sure they are. They SAY they are but the health secretary Matt Hancock said on TV at the weekend that he expects to get through all adults in the uk by autumn which is pretty much exactly 200,000 people a day or 1 million people per working week. They say they will expand but then let slip that they don't actually expect to.
Not quite the same, but it occurred to me that there is no filter for ‘key’ workers, health workers yes but surely someone who works in a Supermarket for example should be above someone like me who is 50, fit and healthy.
In a world of 7 billion people there will be some with a natural immunity who may not be able to pass it on. The virus will tend to mutate to be more like the common cold, quickly mutating, mild symptoms, easily passed on. If a virus mutates to become easy to transfer and deadly it very quickly runs out of hosts to live in and the human race suffers a catastrophic event.
