Aren’t all countries doing boosters? Which countries don’t have boosters? Do you know of any specifically?
This comment surprised me so I looked it up. The WHO report from Jan 2023 says 91 countries are reporting data on boosters. [1] The ‘our world in data’ site shows booster coverage for most of the world, only missing some countries in Africa and maybe small countries and islands too small to see on the map. Aside from the US, there’s booster coverage in Australia, Canada, China, Russia, India, all of Europe, all of South America, among others. This URL has the map view scrolled to May 2022, which appears to be the peak of the data reporting for boosters. [2]
So yes, boosters are being rolled out for older people and at-risk groups, all over the place.
I pretty much found these just by googling: <random country name> covid booster 2023
If/when you are an eligible age, will you get your health authority's recommended annual/winter flu jab? (e.g. the multivalent vacine offered to all eligible older adults in the UK).
