Gold FFM Barrykearley 7,162 Posted February 21 Author Gold FFM Report Share Posted February 21 My eldest is in full house lockdown in Exeter uni accommodation again. She’s had covid and has antibodies, had her jab, is tested twice weekly on her course and she’s now stuck for at least 10 days. She and her housemates have been practicing taking each others blood this evening - since they did that in last weeks practicals.... 😳 1 Quote Only here once Link to post Share on other sites

When I was in the army we had to have a blood sample and urine sample to be tested. We were all sitting in the bar with our little jars of blood and wee while we were waited to be called. After a couple of pints each we were called through one by one...trouble was by this point no one remembered who's was who's so we just had to pick of of each and hope we would be ok! buddsy Quote "Belief is the enemy of knowing" - Crrow777 Link to post Share on other sites
LotusLeftLotusRight 1,416 Posted February 22 Report Share Posted February 22 What do people think of the performance of the two vaccines? As of yesterday, we had administered 17,582,121 first doses, but only 615,148 second doses. Pfizer/Biontech is 85% effective after one dose and 95.8% effective after two doses (Israel research). Astra Zeneca is 76% effective after one dose and up to 81% after two (Oxford University research), so the net gain for AZ second doses is not huge. Do we know what proportion of our vaccines administered to date are from which suppliers? I assume it’s significantly more AZ. Will the protection be enough for everyone to go back to normal by the summer? Quote Link to post Share on other sites
Gold FFM Popular Post Barrykearley 7,162 Posted February 22 Author Gold FFM Popular Post Report Share Posted February 22 Probably better than the 1918 Spanish flu vaccine. Which must have worked since the virus pretty much died out within 2 years. 2 1 Quote Only here once Link to post Share on other sites

In his Commons speech today, Boris gave clear numbers for the effectiveness of the Pfizer/BioNtech vaccine (I think 75% less hospitalisations), but had no data to report about the Astra Zeneca one, since that immunisation regime started later. I guess we’re going to have to be patient and see what happens. Quote Link to post Share on other sites

I had the Astra Zeneca jab purely because that was what they were dishing out on the day, but both have good results as far as I can see. In any case, we'll get what we're given, or not at all.

Gold FFM Barrykearley 7,162 Posted February 24 Author Gold FFM Report Share Posted February 24 Well - my eldest Daisy has tested positive again. Even though she has antibodies - has had her first jab - and is showing no symptoms. That was a test from yesterday - she has another routine flow test again today.

mayevora 1,356 Posted February 24 Report Share Posted February 24 False Positive maybe? I think Exeter Uni was particularly badly hit with it last year. 3 of my pupils had it.

electro_boy 253 Posted February 24 Report Share Posted February 24 It doesn't necessarily mean the test is incorrect. Yes are false positives tests are possible but that is just one possibility. Testing positive for antibodies doesn't mean you can't catch the virus and test positive again on a COVID test. Antibodies don't form a magical force field around your body preventing viruses from entering. Antibodies increase the chance the that your body can fight the virus and hopefully get get rid of it quicker. It is also a possibility that the virus strain has a mutation such that the antibodies are less effective. Which all means there is a window of opportunity where the virus can enter and multiply, before your body detects the virus and starts to fight it. So still possible to test positive on a virus test. And hence the need to still follow good hand hygiene and social distancing after you have received the vaccine or recovered from the virus as you can still harbour the virus and still spread it, infecting others. Also it is very possible that people with the virus are asymptomatic for many days since initially catching the virus and quite possible for their whole encounter with the virus to show no symptoms. Obviously not everyone reacts in this way hence lots of people requiring acute care in hospital. Thats another reason why this virus has spread so much, people are not showing symptoms for quite a few days so are not isolating as they don't know they have the virus so they can go around spreading it and infecting others. 1 Quote Link to post Share on other sites
Gold FFM Barrykearley 7,162 Posted February 24 Author Gold FFM Report Share Posted February 24 I’m confused. It would appear it’s is being suggested that antibodies don’t last very long - if that’s the case - then how in gods name does this vaccine work and how is it the solution??

andydclements 814 Posted February 24 Report Share Posted February 24 The vaccines are designed to produce antibodies, see: https://www.cdc.gov/coronavirus/2019-ncov/vaccines/different-vaccines/how-they-work.html#:~:text=Once vaccinated%2C our immune system,recognize and fight the virus. 1 Quote Link to post Share on other sites
yeller77 124 Posted February 24 Report Share Posted February 24 ^^^ quicker on the keyboard The vaccine indirectly results in antibody production by directing your own cells to produce and react to spike protein. How the Pfizer vaccine works In recovered ppl, a positive PCR test, which test for viral fragments, can persist for weeks after recovery. In most settings and in current thought, the presence of a positive PCR and positive antibody test in a person with no symptoms does not necessarily imply infection or "infectiousness" and would not require quarantine. @BarrykearleyIf no symptoms, why is she being tested? Sometimes it's just best not to look. It's still unknown how long immunity and antibodies persist, likely 3-6 months (I have an acquaintance who was still donating convalescent plasma 9 months after his infection). Fortunately, the immune system has a memory not unlike your/my better half, able to recall and mount a vigorous reaction to a stimulus months or years after the original insult! 1 Quote Link to post Share on other sites
