New rules allowing fully vaccinated international travelers to enter the U.S. beginning in November will exclude those vaccinated by Russia's Sputnik V vaccine, the Washington Post reports.

Why it matters: Sputnik V's exclusion will mean millions of fully vaccinated individuals won't be eligible to travel to the U.S., per the Post.

It will also have a wider international impact, as Russia has plans to distribute its vaccine to around 70 countries.
