SARS-CoV-2 still has one strain. The current vaccines are hyper-targeted at "variants", something much smaller than a strain. Think of "influenza" like "dog", "strain" like "chihuahua" vs "golden retriever", and "variant" like "chihuahua with blue eyes" vs "chihuahua with brown eyes". The distinction can get a bit muddied at the border* but I don't think we've reached that point yet. *Like these dog breeds: https://www.countryliving.com/uk/wildlife/dog-breeds/a345060... |
