National Guard members across the country hit a deadline at the end of last month to be vaccinated against the COVID-19 virus and as of Friday, the Connecticut National Guard had the highest vaccination rate in the country, according to a spokesman. Of the roughly 5,000 soldiers and airmen serving in the Connecticut National Guard, about 20 have explicitly refused the vaccine while another 100 have applied for exemptions to the requirement, which was issued by the Defense Department last August.
