New Scientist article Vaccine causes an increase in viral hepatitis, which is a common side effect.
It’s a common and often deadly complication in the world of vaccines.
The new study shows that, while there was a slight increase in people with viral hepatitis in the group who had received the vaccine, that was not as great as it would be if the virus was caused by a different virus, according to the authors.
“It’s not clear why this was not seen,” said study author Dr Stephen Jones, a researcher at the University of California, Los Angeles.
“If you look at the other vaccines, for example, the diphtheria-tetanus-pertussis vaccine, you’d expect the incidence of viral hepatitis would go up,” Dr Jones said.
“We’re not saying that’s the case here, but we don’t know.”
The team was not able to test for the viral hepatitis by looking at the immune system, but they did see that the group receiving the vaccine had lower levels of the immune response to that virus than the control group.
“That’s a pretty big difference, especially when you look on the whole, we’re not seeing the virus as being more active,” Dr Smith said.
However, the study did not look at viral infection itself, or the type of infection that would trigger the immune reaction.
The researchers say they plan to look at this in future studies.
Dr Jones said the finding could be a clue for how viral infections in the future could be treated.
“The next thing we want to look into is what happens to the immune cells that are actually infected with the virus,” he said.
“Is it just dormant cells that can be killed by the immune systems?
Or do the cells actually have an adaptive immune response?”
We don’t really know yet.
We’re working to find out.
