Delta Variant Accounts for 6 Percent of New U.S. Coronavirus Infections

As reported by The Washington Post, “The coronavirus variant called “delta,” first detected in India, has become the dominant strain in the United Kingdom, despite that country's highly successful vaccination campaign. The variant also now accounts for about 6 percent of infections in the United States. But one vaccine dose offers just 33 percent protection, the data shows, a reminder of how strongly the second shot boosts immunity to the virus. With the United States in the midst of providing vaccines to adolescents and other people who have waited to get them, second doses are critical.”
