ROCHESTER, N.Y. (WHEC) — Johnson and Johnson says two studies show its coronavirus vaccine is effective against the surging delta variant., and offers protection for months.
The company says it analyzed blood samples from eight people who received the single-dose vaccine in the phase three study. According to the company, the vaccine elicited neutralizing antibodies against the delta variant.
Researchers also tested blood taken from 20 people who participated in an early trial.
They found that the immune response generated by the vaccine lasted at least eight months — and actually improved over time.
It is important to note that neither study has not yet been peer-reviewed.
