The Fredericksburg City Council has approved an agreement between Virginia Attorney Mark Herring regarding allocating funds obtained through court settlements concerning the opioid crisis.
Initial doses have been shipped to the US National Institutes of Health for a clinical study.
The new vaccine, called mRNA-1273.351, will be evaluated as a booster shot for people who have already been vaccinated against coronavirus and as a primary vaccine for people who haven t had coronavirus and have yet to be vaccinated.
Moderna said it will also evaluate a multivalent booster shot that combines the new vaccine formulation with the current vaccine.
Additionally, the company said it has begun to test whether a third, lower dose of its current Covid-19 vaccine can increase immunity against coronavirus variants of concern, with some study participants already getting third doses.
