Johnson & Johnson: Immune Response Against Delta

The company announced on Thursday (local time) in New Brunswick, New Jersey, that laboratory tests carried out on the blood of vaccinated persons showed that. Another study showed that the immune response lasted for at least eight months, it said. With the Johnson & Johnson remedy, only one syringe is required for full vaccination protection.

“We believe that our vaccine offers permanent protection against Covid-19 and triggers a neutralizing activity against the Delta variant,” Paul Stoffels, chief scientist of the company, was quoted in the press release. The data are based on two as yet unpublished studies with blood samples from eight and 20 participants. A detectable immune response in a vaccinated person is not necessarily synonymous with actual protection against infection.
