Before revision:  This qualitative change occurs for both types of vaccination strategies: ring vaccination is effective for containing an outbreak until the levels of inaccessibility exceeds approximately 10\%, a combined ring and community vaccination strategy is effective until the levels of inaccessibility exceeds approximately 50\%.
After revision:  We found that ring vaccination is effective for containing an outbreak until the levels of inaccessibility exceeds approximately 10\%, a combined ring and community vaccination strategy is effective until the levels of inaccessibility exceeds approximately 50\%.
