Yes, Argentina is confirmed as paying the following. Sputnik $9,95 a dose. Sinopharm $20,00 a dose. AstraZenaca and COVAX $4,00 a dose.
Regarding the comments around ability to pay for vaccines, I don't actually think it is not able to pay for the shipments in dollars when it falls due.
If we look at the government expenditure the original budget for vaccines was already exceeded by x4 by March 2021 - resulting in yet more money being asked for. AFAIK there has been nothing from COVAX or any lab to support the idea that they have difficulty paying or requesting financing and we know Argentina already made significant downpayments to some labs etc.
Regarding your suspicions about the choice of vaccines ultimately being down to some side-business in typical Argentine government fashion, I would tend to agree that judging by their actions they are prefering labs that can more easily facilitate more opaque dealings:
- In Jujuy the governor who is arranging direct purchase of Sinopharm vaccines was quoted as saying "intermediarios" appeared asking for extortionate prices (this is a common form of corruption here especially involving government contracts, for example you pay and recieve a factura for $20 but only $15 reaches the company you are supposedly doing business with as due to some alleged technicality or another you can't buy/import/distribute/fast-track the product without one)
- As we know, AstraZenaca was chosen for purchase by the government largely because it would be produced here in partnership with a private Argentine lab and a private Mexican lab. The purchase is not from AstraZenaca in the UK but the separate and private Argentine lab. The Mexican side is bankrolled by Carlos Slim and the Argentine side by Hugo Sigman - a businessman will well known links to Kirchnerism. His labs were raided in April under court order to search for documentation related to contracts with the government. (I would suspect that IF there was foul play, this one would be more a case of putting money in the hat - you pay me $4, you get $0,20 or something like this... very hard to ever actually prove without knowing who or what you're looking for)
- This article also states that the government already made a 60% downpayment amounting to around US$54.000.000 despite not reiving any vaccines from them until now
- This week it was announced that Sputnik V would also be produced here by Richmond Labs, another private Argentine lab listed locally. This lab also received government credits to help finance production here that allegedly sent its stock price soaring by 38%. Richmond whose president Marcelo Figueras allegedly has close links with Kirchnerism also and tends to get a good amount of business under them thanks to the Ministry of Health.
- As for Pfizer, even Vizotti admits they never asked for glaciers or did the government ask for bribes. I believe her. Instead the government found some vague legal technicality that the common-man has difficulty comprehending as apparently not even the policymakers can explain it clearly. As a result the government continues to throw its money at the above-mentioned sources.
Usually things just need a little bit of time to start floating to the surface, especially after a feeding-frenzy. At least it should be an entertaining season in the telenovela that is Argentina, whichever way it turns out.
