A.30 is basically dead, well outcompeted by Delta etc. The UK don't report on it now.
"VUI-21FEB-01 (A.23.1 with E484K), VOC-21FEB-02 (B.1.1.7 with E484K), VUI-21MAR-01, (B.1.324.1 with E484K), A.30, B.1.633, B.1.214.2 and B.1.1.7 with S494P have not been observed in the UK or within the international GISAID dataset within the last 12 weeks. These variants are no longer included in the data update."
The biggest pressure on variant mutation right now is vaccine-evasion - so the reason the Delta variant has out-competed it is likely because the Delta variant does an even better job of evading the vaccine.
In general, I'm disappointed that we are not rolling out updated boosters with variant protection. Flu vaccines are updated each year - and here we are almost two years from the initial outbreak, and we're still vaccinating people against the original form of the virus - which isn't even spreading anymore
That's not to say that it's not still lifesaving to get the current vaccine - but F - we can do better!
One of the best (IMHO) Sci-Fi books "His Master's Voice" by Stanisław Lem begins exactly like this.
"It is a densely philosophical first contact story about an effort by scientists to decode, translate, and understand an extraterrestrial transmission. The novel critically approaches humanity's intelligence and intentions in deciphering and truly comprehending a message from outer space."
