A booster dose of Johnson & Johnson’s coronavirus vaccine provided 94% protection against the disease and increased antibodies significantly, according to the company. “Our single-shot vaccine generates strong immune responses and long-lasting immune memory. And, when a booster of the Johnson & Johnson COVID-19 vaccine is given, the strength of protection against COVID-19 further increases,” said Dr. Mathai Mammen, global head of Janssen research and development with Johnson & Johnson. New study results show that a J&J booster given 56 days after the first shot provided 100% protection against severe coronavirus at least two weeks after the shot, and 94% protection against symptomatic coronavirus in the U.
