CLARKSVILLE, TN (CLARKSVILLE NOW) – The number of people getting the COVID-19 vaccine has slowed in Montgomery County even as the Delta variant – which is more contagious and deadly – is surging in parts of the country that have low vaccination rates. The biggest obstacle to increased vaccination is hesitancy among those concerned about vaccine side effects, who don’t think COVID-19 is serious, or both. Clarksville Now recently presented the views of local doctors on the COVID vaccine. This time, we’re talking to our leaders, from Washington and Nashville to Clarksville and Fort Campbell.
