This coverage will cover all costs associated with immunization, including the cost of the vaccine, if incurred by the health care provider, and all costs of vaccine administration. These services shall be exempt from any deductible, per-visit charge and/or copayment provisions which may be in force in these policies, provisions, plans, agreements or contracts.
