The UK hit a grim milestone of 100,000 COVID-related deaths on Tuesday, but currency traders continue to focus on the impressive progress the UK is making towards mass vaccinations.Sterling leapt back through the 1.37 mark versus the US dollar yesterday, while rallying to a fresh eight month high on the euro. Britain has now administered at least one dose of the Pfizer or AstraZeneca vaccine to around 10% of the population, including the vast majority of over 80s. By contrast, the European Union is lagging well behind, with both Pfizer and AstraZeneca saying that production problems means that they are unable to supply the expected quantity of vaccines to the common bloc. The EU is yet to approve the AstraZeneca jab, but it may only be a matter of days until it does. A report from Reuters has suggested that the quantity of the UK produced vaccine may be as much as 60% lower in the first quarter than the EU had initially agreed. This very gradual vaccine rollout in Europe relative to the US and UK is proving a bit of a stumbling block to euro strength, with the common currency stuck around the 1.21 against what has been a broadly weaker greenback in the past 24 hours.
