    COVID Covid Variant Omicron (B.1.1.529)

    Do the unvaccinated really dominate hospital admissions in the UK? Aren't many cases in the older age groups fully vaccinated? It's those who would benefit the most from the booster. Vaccinating younger age groups might also help reduce transmission. Also, if neutralizing antibodies contribute...

    COVID Covid Variant Omicron (B.1.1.529)

    In original antigenic sin, the response to variants would be less effective than to the original virus. Data shows that antibodies after the second dose are more effective at neutralizing the original virus than to the Beta variant. A booster at 9 months not only increases antibody levels, but...

    COVID Covid Variant Omicron (B.1.1.529)

    In South Africa, 70-80% of the population has been previously infected, 24% vaccinated, and the average age is relatively young, all of which are expected to provide protection against Covid, so this may be why all of the cases Dr Angelique Coetzee (Chairperson, board of the South African...

    COVID Covid Variant Omicron (B.1.1.529)

    That's not clear. For both infection and double vaccination, substantial protection against severe illness is expected to remain, because the RNA vaccines use a full length spike, which allows many epitopes (T cells, non-neutralizing antibodies) apart from those targeted by neutralizing...

    COVID Covid Variant Omicron (B.1.1.529)

    The UK overall is in a decent position relative to say Germany, because its population immunity to covid is very high. Nonetheless, the NHS is under pressure, which is why the government has been trying to roll out booster shots both to reduce severe illness among those already vaccinated, as...

    COVID Covid Variant Omicron (B.1.1.529)

    Prof Rudo Mathiva (head of ICU at Chris Hani Baragwanath Hospital, South Africa) says they have to persuade more young people (young 20s - late 30s) to get vaccinated, as they are seeing more young covid patients in hospital (65% unvaccinated, 35% partially vaccinated).

    COVID Covid Variant Omicron (B.1.1.529)

    Also, South Africa is estimated to have 70-80% population immunity from either infection or vax, data does not yet indicate milder disease (compared to previous variants) for unvaxxed. Vax is still expected to be hugely protective against severe disease (because of T cells), so main thing is...

    COVID Covid Variant Omicron (B.1.1.529)

    They were forced :oldtongue: to skip Nu after Professor Aris Katzourakis of Oxford University tweeted "'Nu' is pronounced 'Ni' or 'Nee' (as in, the knights who say ni, not 'new')." Now he is saying "OK you do know that in Greek, omicron is pronounced “Ekke Ekke Ekke Ekke Ptang”".

    COVID Covid Variant Omicron (B.1.1.529)

    Systematic creation of mutant viral-mimics found a mutant that escapes all antibodies produced by infection or vaccination. However, the mutant did not escape antibodies produced by infection+vaccination. So it is likely that Nu (B.1.1.159) would also not escape antibodies produced by...

    Are the COVID Vaccines Unusually Ineffective?

    https://movementdisorders.onlinelibrary.wiley.com/doi/10.1002/mds.28851 A total of 181 patients with PD met the inclusion criteria; 107 men and 74 women were included. Mean age was 65 years old (range, 31–99). A total of 178 patients received two doses of the SARS-CoV-2 vaccine (177...

    COVID Make Sure You Check With Your Doctor To See If You Need A Third Jab

    I think you could wait 3-6 months before taking it, since being infected is like getting a booster. https://www.medrxiv.org/content/10.1101/2021.10.18.21265113v1 Immune Responses in Fully Vaccinated Individuals Following Breakthrough Infection with the SARS-CoV-2 Delta Variant in Provincetown...

    Implications of Covid becoming endemic

    I think on a one round of full (double dose) vaccination it will still be worse than the flu. The UK after opening up is on track for 40,000 deaths a year, which is 3x as bad as an average flu year (and twice as bad as a bad year). Maybe they can bring it down with boosters. But it could be...
