Johnson & Johnson’s Covid-19 vaccine increases the strength of protection against the virus and its duration as well, the company said in a statement on Tuesday. "Our large real-world evidence and phase 3 studies confirm that the single-shot Johnson & Johnson vaccine provides strong and long-lasting protection against Covid-19-related hospitalizations," said Mathai Mammen, MD, PhD, global head at Janssen Research & Development, Johnson & Johnson. “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," added Mammen.
