J&J says second shot boosts protection for moderate-severe COVID-19 to 94%

CHICAGO, Sept 21 (Reuters) – Johnson & Johnson (JNJ.N) said Tuesday a second shot of its COVID-19 vaccine given about two months after the first increased its effectiveness to 94% in the United States against moderate to severe forms of the disease.

That compares to 70% protection with a single dose.

The data will help J&J make its case to U.S. regulators for a booster shot even as the company stresses the durability of its single-shot vaccine as a tool to ease the global pandemic.

President Joe Biden is pushing for booster shots in the face of surging hospitalizations caused by the Delta variant and J&J, the only drugmaker with a single-shot COVID-19 vaccine approved in the United States, has been under pressure to produce evidence on the effectiveness of an additional dose.
