This is BA.4.6, the new subline of the ‘Micron variant’

Among the many subtypes of SARS-CoV-2, micron is the most sublinear (so far) generated, with BA.4.6 being the newest of them all.

Despite the fact that according to the World Health Organization (WHO), the Covid-19 pandemic is taking its final blow, the SARS-CoV-2 virus does not understand termination, so it remains in its thirteenth time and continues to mutate, Generates new strains and subtypes among populations. Such is the case with the BA.4.6 sublineage, which was first publicly recognized by the British government on 1 September.

But what is BA.4.6?

For now little is known about its origin, although it is known that it currently represents more than 4 percent of COVID-19 cases across the United Kingdom. As a sub-lineage of ómicron, BA.4.6 is a recombinant-type mutation that arises when two variants infecting the same individual create a new genetic mutation, which is directly linked to immune evasion. Is. In this sense, it can be said that BA.4.6 is more permeable, although, yes, not more serious.

Notably, this sub-lineage contains a mutation in an antigenically important site, which immediately identifies it; But it has (apparently) a small development advantage over BA.5, which could give it even greater resistance to the full vaccine regimen, or so experts shuffle.

We are talking about a subtype of Omicron, so BA.4.6 brings together the symptoms of the said strain of coronavirus, in the absence of a list of its manifestations, ranging from fatigue and cough to fever or headache, officially is not defined. , An infection that can also trigger other effects such as sore throat, diarrhea, and even a short incubation period for the virus.

Finally, it should be said that at this time, the United States is the second country in which BA.4.6 has been detected and reported several cases among its COVID-19 patients.

Of the remaining forms of infection, which the micron variant has found to place the population under the yoke of the coronavirus, it is BA.2, BA.2.75, Ba.4, Ba.5… among others, the latter two being noted. deserves to be given. Genealogy is destined to predominate in the European Union.

A vaccination campaign that would not protect this specific lineage

For its part, FOAM or the Federation of Andalusian Organizations for the Elderly has called on Health to halt its vaccination campaign of a second booster dose against the coronavirus, and more precisely its vaccination campaign for people over the age of 80. and permanently targeted in residences.

your bet? Instead of going ahead with a vaccination scheduled to be administered at the end of what would be the fourth puncture in Spain, wait for the European Medicines Agency’s authorization on vaccines adapted to the current major subtypes of micron. month; Especially when they consider that plans to inject bivalent vaccines “contribute nothing to the current monovalent ones”.

And it is that the vaccine that Health will make upon request for approval last September 1 by AEM has nothing to do with BA.4.6. In fact, the serums that will soon be hitting the country are in line with the original versions of Comirneti and Spikewax (from Pfizer and Moderna, respectively) with the micron BA.1 subvariant, currently extinct, as well as protecting against early forms. are built for. of SARS-CoV-2.

In this federation’s opinion, the best thing to do is to follow the example of the US FDA, which has also approved divalent sera, although they contain two very different strains to those vaccinated in Spain: the original virus. and of the subtypes of micron BA.4 and BA.5, which are currently predominant worldwide.
