Johnson & Johnson's single-dose COVID-19 vaccine shows promising signs against Delta variant
Johnson & Johnson on Thursday said that its single-shot of COVID-19 vaccine showed promising signs of protection against the Delta variant rapidly spreading across the US and other countries, in a small laboratory study, according to news agency ANI.
According to the company report, the vaccine generated strong, persistent activity against the rapidly spreading Delta variant and other highly prevalent SARS-CoV-2 viral variants. In addition, the data showed that the durability of the immune response lasted through at least eight months, the length of time evaluated to date. The two preprint study summaries have been submitted today to bioRxiv, a non-profit preprint server for the life sciences, ANI said.
The single-dose vaccine, elicited neutralising antibody activity against the Delta variant at an even higher level than what was recently observed for the Beta (B.1.351) variant in South Africa, the report stated.
"Today's newly announced studies reinforce the ability of the Johnson & Johnson COVID-19 vaccine to help protect the health of people globally," Paul Stoffels, MD, Vice Chairman of the Executive Committee and Chief Scientific Officer at Johnson & Johnson was quoted as saying in ANI report.
"We believe that our vaccine offers durable protection against COVID-19 and elicits neutralizing activity against the Delta variant. This adds to the robust body of clinical data supporting our single-shot vaccine's ability to protect against multiple variants of concern," Stoffels added.
Meanwhile, the World Health Organization on Thurday said the Delta variant of COVID-19 is now present in nearly 100 countries as per conservative estimates, and warned that in the coming months the highly transmissible strain will become the dominant variant of the coronavirus globally.
