Finally, the Conferees note that they have prohibited States from imposing additional qualifications as providers enrolled in the programme. The Conferees have done so because, as stated above with respect to the enforcement of claim rights, they are attempting to prevent any attempt by a State to require that patients be transferred from a qualified and consenting provider to another site. The Conferees also strive to ensure that federally vaccinable children can choose the provider they wish to use for this benefit. The VFC programme, which began operationally on 1 October 1994, is an unprecedented approach to improving the availability of vaccines throughout the country by providing free vaccines to children eligible for VFC through registered public and private providers. The Conference notes that the provisions of the Agreement are simple with respect to suppliers and stress the intention that the Secretary and States implement these provisions in an equally straight manner, in order to encourage vendors to participate while maintaining responsibility for the programme. The Conferees recognize that different states have a large number of vaccine distribution programs in place and intend to maintain existing effective distribution systems, including the use of independent wholesalers. As part of the conference agreement, states must establish a pediatric vaccine distribution program to complement their Medicaid plans, although this program is available to a larger class of children than those receiving general Medicaid services and (2) program providers may include a larger class of providers than those who agree to be Medicaid providers. (The Conferees indicate that providers who have not chosen to provide Medicaid can continue to participate in this new program.) With the exception of children eligible for the program because of their status as Medicaid recipients, Medicaid authorization requirements should not be applied to determine which children are eligible for a free vaccine.
