The results suggested that the best way is to quickly deliver second doses and provide boosters to those whose immunity may not be high enough against these new variants.
The latest Lancet study supports UK’s plans to reduce the dose gap between vaccines. It was found that people were less likely to develop antibody levels against the Delta variant, after just one dose of the Pfizer-BioNTech vaccine.
