  • Covid Wave number 7 is upon us in Australia

    Covid Wave number 7 is upon us in Australia

    Sigma (BA.2.75.*) is in Australia and has been for over a month but is now starting to grow in prevalence compared to Pi (BA.5.*). Don’t forget to get that fifth jab in. Klaus Schwab recommends it. The nomenclature is a bit confusing. Greek letters should have been assigned to BA.2.* (Rho), BA.5.* (Pi) and now…

  • New Omicron variants of concern are exploding in number. Next wave will be BA.2.75.

    New Omicron variants of concern are exploding in number. Next wave will be BA.2.75.

    Some time ago I questioned why BA.2 and all subvariants like BA.2.* (* being wild card) where even listed under Omicron as they were vastly different to the BA.1.* subvariants. BA.3 was a lot like BA.1 but has since vanished because it was less contagious. Anyhow people have now separated all the BA.2 subvariants in…

  • Any immunity to BA.1 is useless against the new Omicron variants BA.4 and BA.5

    Any immunity to BA.1 is useless against the new Omicron variants BA.4 and BA.5

    Immunity to BA.1 is useless against the new Omicron variants. I have always said that BA.2 is different to BA.1, and BA.4 and BA.5 are more like BA.2 with the extra mutation L452R found on the Delta variant, so I am not surprised by this at all. It is concerning that the immune escape of…

  • The BA.2 subvariants > BA.1 subvariants in the UK. Deaths Rising.

    The BA.2 subvariants > BA.1 subvariants in the UK. Deaths Rising.

    Just a quick update on what the variants are doing in the UK. It seems the BA.2 subvariants and all growing while the BA.1 subvariants are being replaced. BA.2, BA.2.3, BA2.9, BA.2.10, and BA.2.12 are all growing in prevalence with BA.2.9 probably growing the fastest and BA.2 the slowest. All the BA.1 subvariants are reducing…

  • BA.2 is not Omicron. And what are BA.4 and BA.5?

    BA.2 is not Omicron. And what are BA.4 and BA.5?

    BA.2 is very different to BA.1 and BA.3. Why is it called Omicron? Because it came from South Africa around the same time. I thought the whole purpose of using Greek letters was so we could not tell where the variant came from. Delta always reminds me of the Ganges delta plains and hence of…
