The “sunshine” vitamin may help the immune system fight the virus and avoid severe respiratory distress.

Researchers were careful to note that the findings do not support the idea that HBV exposure is ’desirable’ from a public health perspective.

The liver-damaging virus seems to successfully restrain a dangerous immune response that causes the body to reject new organs.

More needs to be done to increase HBV immunity rates among at-risk adults in the country.
