BA.2.12.1 is most infectious. BA.2.2 is most deadly. BA.2.23 looks ominous.
I know this from what is going on in the USA and Hong Kong respectively. BA.2.12.1 is overtaking all other variants atm in the USA. BA.2.2 has a higher CFR than other BA.2.* variants. Here is the genetic structure of their Spike protein some other BA.2 relatives. Once again I point out that BA.2 is…

Why is China so keen to stay #zerocovid?
There are lots of reasons, and I believe Australia should have stayed #zerocovid as well. People could have still travelled etc but they would just have to quarantine when they came home. For many it could have been home quarantine. Back to China. Why are they so keen to stay zerocovid? The coronavirus is a…

Vaccine passports are such a joke, and hence so is mandating a vaccine that does not work so well. I am thinking most people are complete idiots.
I calculated that 98.6% of adults who are infected in the first week on 2022 where fully vaccinated, which some obvious logic means 98.6% of all you have covid19 are fully vaccinated. And if “vaccine passports” are bullshit then so are “vaccine mandates”. They who have perpetrated this crossed violation of one of the most…

Australia thinks herd immunity is possible. It is not.
When Australia started to mandate the vaccine, it must have thought herd immunity was possible but it was not, and that was with the delta variant in August/ September/October 2021. I have calculated that the R naught value of delta variant is about 12.5. Here is a graph I circulated lat year. Th R naught…

Move over for BA.12. Ten-times more infectious than BA.2
A new variant of the novel coronavirus, BA.12, was found in Bihar’s Patna on Thursday. According to the state’s health department, the new variant of Omicron was found in the Indira Gandhi Institute of Medical Sciences (IGIMS). There is a new kid in town and we have not dealt with waves from BA.2.9, BA.2.2, BA.2.12, BA.2.12.1,…

Omicron BA.4 and BA.5 are coming.
You just have to look at these graphs showing how quickly they have grown in prevalence in South Africa. In a month or two we will be the same. BA.4 and BA.5 are more like BA.2 than BA.1 (BA.3 seems to have disappeared almost). The both have the mutation of concern L452R that was found…

Omicron now has 73 subvariants
Omicron B.1.1.529, now has 73 subvariants. These variants are being generated in the huge “virus pools” of vaccinated people as I have repeatedly noted since July 2021. The Delta variant generated 245 sublineages. The problem is that vaccines do not stop infection and transmission of the coronavirus. Currently vaccines have an efficacy of about 30-40%…

What is going to happen in China?
China is in a real tight spot right now. It wants to maintain #zerocovid for good reason but omicron seems to be so infective and it has some of the densest population areas in the world, and more importantly most of these areas live and work inside where aerosols are most active. 97% of all…

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…

Petri Dish Cruise ships will now be allowed back into Australia.
It seems the world has given up on covid19 and are going to let it spread/rip. With 100 million people actively infected inside a constant “virus pool”, anything is still possible. Mutations are are of less concern than recombinants which are highly likely. We are far from out of the woods., Denmark’s CFR went from…
