Not all COVID vaccines equal for EU

After Dr. Ifeanyi Nsofor and his wife received two doses of AstraZeneca’s coronavirus vaccine in Nigeria, they assumed they would be free to travel this summer to a European destination of their choice. They were wrong.

The couple — and millions of other people vaccinated through a U.N.-backed effort — could find themselves barred from entering many European and other countries because those nations don’t recognize the Indian-made version of the vaccine for travel.
