‘It’s pretty marginal’: Experts say Biden’s vaccine waiver unlikely to boost supply quickly

The Biden administration’s support of a petition to ease patent protections for vaccines elevated the global battle against the coronavirus as a central plank of U.S. foreign policy, but myriad hurdles remain before that stance could become international policy — if ever.

As a result, it could be months, or longer, before the World Trade Organization reaches an agreement to temporarily waive the protections and years before countries build factories and amass the materials and expertise to produce the vaccines, experts say.
