Reinfections with Covid, and Recombinants.
In 2021 there were a few documented cases of reinfection with covid, but the rate of reinfection has now confirmed it to be quite common. This means that there is no natural immunity. Even if a person was to develop natural immunity to one variant, they can get re-infected with another variant. There are currently…

Patient with coronavirus for 471 days has 3 variants that evolved within him.
That is like 15 months. Apparently the poor guy just could not shake the virus off and scientists say at least 3 different variants/strain evolved just inside him that they know of. Carrying different variants or strains simultaneously can lead to crossover and recombinant variants. This is sex for a virus, and potentially a quantum…

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…

Omicron BA.1, BA.2,BA.4, BA.5, BA.12, then omicron recombinants deltacron, Omicron XA, XB, XC, XD, XE, … , XW, XX, XY, XZ, XAA, XAB, … , etc., BC.1, BC.2, BD.1, BD.1.1, etc.
Most people would have heard of “deltracron’, a recombinant variant made from the omicron and delta variants. I do not know if deltracron has survived. Most people would also have heard of the recombinant Omicron XE, which is a recombinant of Omicron BA.1 and BA.2. The status of Omicron XE is also unknown. Why are…

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…

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