The data, which has not yet been peer reviewed, is preliminary but promising.
In the experiments, scientists took blood samples from people who have already been vaccinated and tested it against variants in a laboratory. This type of experiment can offer a rough sense of whether the vaccine will work against a new variant.

The Moderna vaccine appeared to work against all variants, as indicated by so-called "neutralizing antibody titers."
Some of the variants -- including Delta (first identified in India), Beta (first identified in South Africa), and Gamma (first identified in Brazil) -- showed a slight reduction in these neutralizing antibody titers, but scientists say these slight reductions aren't enough to evade the vaccine.
This type of experiment does not indicate an exact percentage of exactly how effective Moderna's vaccine is likely to be against each variant.
A prior real-world study from the United Kingdom indicated the Pfizer vaccine, which uses a similar mRNA technology, was 88% effective against the Delta variant in terms of protecting people from symptomatic disease.

Taken collectively, these studies are encouraging news that mRNA vaccines are holding up against the Delta variant.
