A study out of New York University suggests the Johnson & Johnson COVID-19 vaccine may be less effective in fighting off the delta variant that's causing problems around the country. But a University of Minnesota virologist said the findings aren't as concerning to him.
It's important to note these findings have not been peer-reviewed. The delta variant is dominating COVID-19 cases in the U.S. Some said the J&J vaccine comes with lingering doubt.
Daniel Han got the one-stop shot but is now having second thoughts.
"I'm kind of scared because I don't know if my vaccine is going to be effective toward this new variant," Han said.
The new NYU study suggests the Johnson & Johnson vaccine puts up a weak fight against the delta variant compared to the original strain of the virus.
Louis Mansky, the director of the U of M's Institute for Molecular Biology, explained the research shows the J&J vaccine still protects patients from hospitalization and death.
"Looking at that data doesn't concern me at all that this would be a serious detriment to the general effectiveness of the Johnson & Johnson Janssen vaccine," Mansky said.
He added that the study shows there's a slight drop in J&J's antibody response fighting off the delta variant but the vaccine is still doing its job.
"It's not anything that should pose a serious threat to the effectiveness of that particular vaccine," Mansky said.
In the findings, researchers said millions of J&J patients may need a booster shot but Mansky said there's no scientific evidence to support that at this time.
"There's a lot of things that are possible but the way science works is that it's a process where you collect data and the data is independently reviewed to confirm that people believe that it's true," Mansky said.
The expert added that it's natural for a virus to mutate, so we'll likely continue to see more variants.
He said the big question scientists are working to find out is, "What's the durability of the current vaccines?"
