Yes...that's good to see Steve.
Listening yesterday to R4 and a guest (scientist) was talking about research they are doing on the effectiveness of the Pfizer vaccine on the new variants.
Interesting to hear that the variations in the virus are stemming from it staying in people who can't fight it off and therefore the virus is staying in contact with the human immune system and adapting it's variants from that. Which is different from the way other Sars viruses have mutated. They traditionally move quickly from host to host and the viruses mutates without coming into contact with the immune system.
Their work is currently on the Brazilian, SA and UK variants.
Most interesting. |  |

Also on vaccination, this Twitter thread is an excellent visualisation of rates of effectiveness:

just a side question. this is the oxford vaccine , i have had the first of the pfizer vaccine, plus there other vaccines coming shortly. so will they pick one universal vaccine later down the road ?
i'm glad i have mine but will people say i dont want one because another got a higher success rate |  |

Got my first next week, Pfizer.
Having not looked too closely, I assume the studies on this and transmission reducing are strong on both Pfizer and the Oxford/AZ? |  | | |

i'm a little puzzled by the stats.
So if something has 76% efficacy and 99% prevention from serious illness, i assumed that means there is a 76% chance you won't get the disease if you become infected because of the vaccine immune response.
So if that assumption is correct, is the vaccine cutting transmissibility applicable to every infection, or just the 76% that the vaccine prevented from becoming a disease? [Post edited 3 Feb 2021 19:00]

I think you're describing something like this graph in the tweet here, infections happen but are asymptomatic so - in this scenario - people could still pass the disease on but not suffer from it themselves.
However, the Oxford vaccine seems to do this and reduce the infection significantly.

I'm not entirely sure what i mean! When i say infected i didn't mean catching the virus, i meant exposure to the virus but not catching it because of the vaccine, and you would have caught it had you not been immunised. Asymptomatic cases are still catching the virus and testing positive as far as i am concerned.
So looking at the below i'm now confused of what efficacy means. Does that mean prevention of positive cases or just prevention of symptomatic cases? | |
