I was wondering about this also... is it simply possible that by mid-2021 most places in Latin America, Argentina included, did so poorly in preventing (and detecting) previous infections that combined with more recent vaccination programs we already reached that dirty word of “heard immunity” for COVID in general?

... we already reached that dirty word of “heard immunity” for COVID in general?

This is a wishful thinking. The delta variant will spread here, it is only a matter of time. Hopefully by that time the major vaccine manufacturers will produce vaccines tailored specifically to delta, not the original strain. But it looks like the game in general is here to stay.

A cuántas personas hay que vacunar contra el COVID-19 para alcanzar la inmunidad de rebaño en Argentina

El país está aún lejos de alcanzar la inmunidad de rebaño por inmunización, dijeron expertos en infectología a Infobae. Las variantes llevarían a que se necesiten más vacunados para lograr esa inmunidad para reducir la circulación del virus

How many people must be vaccinated against COVID-19 to achieve herd immunity in Argentina. The country is still far from achieving herd immunity, infectology experts told Infobae...the possibility of achieving the so-called "herd immunity" or "collective immunity" is still a long way off. Infectious disease experts from the country consulted by Infobae estimate that it would be necessary to vaccinate at least 80% of the population with the two doses to achieve herd immunity by immunization...

The delta variant will spread here, it is only a matter of time. I AGREE.
Hopefully by that time the major vaccine manufacturers will produce vaccines tailored specifically to delta, not the original strain.
The issue here is when will ARG purchase those specific vaccines? Most likely not until 2022? By then the Delta variant will have done its deed here.

por qué el Gobierno impulsa una segunda dosis distinta para AstraZeneca / Sociedad

Mientras que en Argentina se destacó la necesidad de administrar vacunas contra el coronavirus con dosis de diferentes laboratorios como

titulares.ar

"Formula Merkel"....why the Argentine gov't promotes inoculation with a different vaccine as the second dose for Oxford-AstraZeneca. The
initiative of the combined schemes includes an extra option, of which little and nothing has been said so far: the "cross" of Oxford- AstraZeneca with Moderna....Given that Pfizer and Moderna are "cousins" (both from the US, both built on mRNA platforms), it was logical to assume (as Merkel would have done) that the result of both acting as "drivers" (reinforcement) for AstraZeneca would be more or less similar....

....The Gov't not only promotes that those who started their scheme with the Russian vaccine can complete it with AstraZeneca or Moderna,
but also that those who started with AstraZeneca can complete it with Moderna....We must not forget the context: the authorities are pending the administration of second doses in the face of what they consider an imminent wave (whose magnitude no one can predict, for now) by the Delta variant, whose severe effects are only manageable with full vaccination schedules....

....As Daniela Hozbor, “Vaccinologist” at the Institute of Biotechnology and Molecular Biology (IBBM) and professor at the UNLP, explained to Clarín, “these schemes generate a more robust response even for the most difficult variants to induce protection, such as the beta variant” ("Former" South Africa)....The authors of the report also say that Moderna would be an excellent choice as a third dose for those who have received the full AstraZeneca scheme. The second issue for which it makes sense to promote heterologous vaccination is timing. The more auspicious the data from the laboratory's pooling, the easier it will be to increase the scope of vaccination, which is now progressing faster but started too slowly in the country. In the face of a potential advance of Delta (or any other variant, in the future), new safe and effective combinations will give more plasticity to any campaign....

I generally agree if looking at a total population of a country. However if we look at the population of major cities and population center where the virus spreads more rapidly, and is thus more noticeable, perhaps it looks a little different.
For example here in CABA we have a population around 3.000.000. There have been 500.242 detected infections to date (which we can guess in much higher in reality) which should generate some immunity, plus 2.000.000 at least partially vaccinated and 700.000 fully vaccinated, again generating more immunity. This would suggest there are few completely unprotected people left in the city, meaning the impact of COVID would not be very noticeable in terms of ICU occupation and hospital admissions. Additionally as symptoms may be milder even for those with partial immunity, less people may think to get tested and thus recorded as positive cases.

I have been doing similar calculations for some time to try and work out when I could start feeling safer, but found it really difficult. Of course, there are many more cases than reported cases. But so many infected people (reported and unreported) will have also been vaccinated by now (once or twice), that there will be plenty of double counting, and we have no way to know how much. Not to mention the complication that whilst 3 million people sleep in the city, another 3 million enter it to work every day. In the end, I decided to stay on full guard until around 70% of the city is officially double vaccinated. But even then, only for a while. As it seems clear that the breakthrough cases are much higher than we were initially led to believe they would be when the trials were reporting effectiveness rates of over 90%, and as it seems apparent that this is due at least in part to the effectiveness waning over time (I've heard a couple of times now that the Israel date is showing that the breakthrough infections are concentrated in those who first got the vaccine at the start of the year), it seems we will be vulnerable again reasonably quickly unless they follow up the double vaccination with the first boosters.

If it is true that vaccine effectiveness wanes over say six months, and if that means in turn that each one of us is more likely to become a breakthrough case as time rolls on, my question is this: is the vaccine just as likely at the six-month mark to protect us from serious illness as it was at the start, or does its protection against serious illness also drop? Can we temper our knowledge that our protection against infection will drop with confidence that our protection against serious infection will not? I'd like to see some reporting on that.

It is certainly a relief for those of us in the twilight zone between AstraZeneca 1 and AstraZeneca 2 that Delta's arrival seems to be delayed.

Your theory is plausible. I hope that is what comes about in CABA.

I certainly would like to know as well.

I agree. I was vaccinated on July 7th with the first dose of Oxford/AstraZeneca. I am eligible for the second dose after the first week in Sept. Will that 2nd shot with A/Z or Moderna materialize in due time? Either way I will get inoculated again in San Francisco with 2 doses of Moderna. Two weeks ago I bought a r/t ticket on Avianca leaving in mid-Oct with a return date in mid-Nov using my voucher from April, 2020.
