The one-shot coronavirus vaccine from Johnson & Johnson is much less effective against the Delta variant than it is against the original version of COVID-19, according to a new study posted online Tuesday.
The study, which examined blood samples in a laboratory setting and has not yet been peer-reviewed, suggests that anyone who received the J&J vaccine may need to receive a second shot as the variant continues to spread across the US.
“The message that we wanted to give was not that people shouldn’t get the J&J vaccine, but we hope that in the future, it will be boosted with either another dose of J&J or a boost with Pfizer or Moderna,” study leader Nathaniel Landau, a virologist at NYU’s Grossman School of Medicine, told The New York Times.
Earlier this month, New Jersey-based Johnson & Johnson published preliminary data indicating its vaccine was effective against the Delta variant, first located in India, at least eight months after inoculation.
