Some vaccine-makers are preparing customized, variant-specific formulas, but none appears close to public use. Pfizer-BioNTech has tailored a form of its vaccine to target the delta variant’s spike protein, though this is not yet being tested in people. Moderna, too, has a candidate vaccine that’s specific to delta. But the company is not testing a delta-centric version in people, either, in part because data on people who have had a third dose of the original vaccine shows boosted antibodies that neutralize delta.
