By the thousands, U.S. service members are refusing or putting off the COVID-19 vaccine as frustrated commanders scramble to knock down internet rumors and find the right pitch that will persuade troops to get the shot. Some Army units are seeing as few as one-third agree to the vaccine. Military leaders searching for answers believe they have identified one potential convincer: an imminent deployment. Navy sailors on ships heading out to sea last week, for example, were choosing to take the shot at rates exceeding 80% to 90%. Air Force Maj. Gen. Jeff Taliaferro, vice director of operations for the Joint Staff, told Congress on Wednesday that "very early data" suggests that just up to two-thirds of the service members offered the vaccine have accepted. "We believe that, of course, the vaccine is the right thing to do." Adding, "It's clearly safe for service members and we need to continue to educate our force and help them understand the benefits and ensure there's leadership involvement in the discussion of the benefits of the of the vaccine." That's higher than the rate for the general population, which a recent survey by the Kaiser Family Foundation put at roughly 50%. But the significant number of forces declining the vaccine is especially worrisome because troops often live, work and fight closely together in environments where social distancing and wearing masks, at times, are difficult. Taliaferro told the House Services Committee, "The services and the combat commands have worked very hard over the last year to make sure that we can operate in a COVID environment before vaccines were available. The addition of the vaccine should make us more capable in that environment. But we've already demonstrated over the last year that we're fully capable of operating in a COVID environment." The military's resistance also comes as troops are deploying to administer shots at vaccination centers around the country and as leaders look to American forces to set an example for the nation. Service leaders have vigorously campaigned for the vaccine. They have held town halls, written messages to the force, distributed scientific data, posted videos, and even put out photos of leaders getting vaccinated. For weeks, the Pentagon insisted it did not know how many troops were declining the vaccine. On Wednesday they provided few details on their early data. Officials from individual military services, however, said in interviews with The Associated Press that refusal rates vary widely, depending on a service member's age, unit, location, deployment status and other intangibles. The variations make it harder for leaders to identify which arguments for the vaccine are most persuasive. Because the vaccine hasn't gotten final approval from the Centers for Disease Control and Prevention, it's voluntary. But Defense Department officials say that soon may change.
