This pre-print (edit : now published apparently!) argued that the likelihood of clots from Covid was still higher than AZ vaccines https://www.medrxiv.org/content/10.1101/2021.03.19.21253980v1.full https://www.medrxiv.org/content/10.1101/2021.03.19.21253980v.... Fauci agreed with their conclusions (https://www.cbsnews.com/news/covid-vaccine-blood-clots-risk-disease/ https://www.cbsnews.com/news/covid-vaccine-blood-clots-risk-...) but disagreed with the aspects of this study that looked at mRNA vaccines and blood clots (but hasn't given reasons why he disagrees with this aspect).

  "While the AstraZeneca vaccine has been the focus, other vaccines have also been reporting adverse events. Searching the EMA EV database for Moderna vaccine reports for deep vein thrombosis and pulmonary embolism identified 29 DVTs, of which 12 also had pulmonary embolism; no reported deaths or fatal events [16]. Similarly, searching for the Pfizer vaccine reports, 13 DVTs were found in the same study period, from 17 February to 12 March, as this paper reporting on the AstraZeneca vaccine adverse events. With the Pfizer vaccine, 11 people also developed pulmonary embolism and two died [16]." Seems to be the case that Pfizer and Moderna didn't get in as much trouble with clot risk I guess?

    Not necessarily, we can't draw any conclusions from these numbers without knowing how many vaccines were administered and to whom.

      Agreed, but I doubt that the difference in # of AZ and Moderna/Pfizer doses administered is off by too many orders of magnitude [edit : on second thought, could be off by a factor of 10]. The central issue in my mind is the difference in populations since Americans have predominantly received Pfizer/Moderna while Brits have predominantly received AZ. Its possible that Brits have an intrinsically higher clot risk with the AZ preparation than Americans do with the Pfizer/Moderna vaccines (although, the J&J clots in the US certainly questions this idea too).
