WASHINGTON — The Biden administration said Friday that it did not know that a Baltimore factory had discarded millions of possibly contaminated doses of AstraZeneca’s coronavirus vaccine when President Biden last month released the company to ship vaccines manufactured there to Mexico and Canada.

And the new vaccine could be far easier to make.
