A new strain of COVID-19 first discovered in South Africa was declared a variant of concern by the World Health Organization on Friday. Here's how the pharmaceutical industry plans to address the latest coronavirus curve ball.

Vaccine makers are already pivoting their efforts to combat the new variant: testing higher doses of booster shots, designing new boosters that anticipate strain mutations, and developing omicron-specific boosters.

In a statement sent to NPR, Moderna said it has been working on a comprehensive strategy to predict variants of concern since the beginning of 2021. One approach is to double the current booster from 50 to 100 micrograms.

Pfizer and BioNTech told Reuters that it expects more data about the omicron variant to be collected within two weeks. That information will help determine whether or not they need to modify their current vaccine. Pfizer and BioNTech said that a vaccine tailored for the omicron variant, if needed, could be ready to ship in approximately 100 days.

Johnson & Johnson said in a statement sent to NPR that it too is already testing its vaccine's efficacy against the new variant. ...
