The US Air Force has become the first military branch to face mass refusal to vaccinate since it became mandatory two months ago, with around 12,000 servicemen refusing to get the Coronavirus vaccine shot.

Iran PressAmerica: As of early October, roughly 60,000 members of the Air Force were unwilling to get vaccinated, according to Pentagon Spokesman John Kirby.

As of the last month, 94 percent of the Air Force have been vaccinated, but the rate has slowed down in recent weeks. Those who fail to meet the deadline may be dismissed or be charged by the military justice system, but the exact sanctions are unknown yet, according to Newsweek.

Kirby noted that the number of servicemen asking for religious exemptions is "very small".

Earlier in August, the US Department of Defense announced that vaccination against COVID-19 would become mandatory for 1.3 million people on active duty, otherwise, servicemen would be penalized.
