How Effective Are COVID-19 Vaccines Against the Delta Variant?
The Delta variant is now quickly spreading across the United Kingdom, which, despite its success in vaccinating the majority of its population, has 60 percent of its cases infected by this variant.
A recent study published in the medical journal The Lancet has raised concerns, because it states that the Pfizer vaccine, known to have an efficacy of 94 percent, produced five times lower antibodies against the Delta variant compared to the original variant.
Many countries apart from India and the UK are also reporting Delta variant COVID cases. The US has 6 percent (and growing) of its cases infected with the Delta variant, Germany 2 percent, and Italy and Spain about 3-5 percent.
