The bill, S.B. No. 1887, proposes to amend the Health and Safety Code of Texas by adding a new section, 161.0053, which prohibits the administration of immunizations using products that contain messenger ribonucleic acid (mRNA) material. The bill defines "mRNA material" as substances that introduce mRNA corresponding to a viral protein. It explicitly states that no person may administer such products for immunization purposes, although it makes an exception for mRNA products used in the treatment of cancer or genetic disorders. Additionally, this prohibition is set to expire on September 1, 2035.

The bill is scheduled to take effect on September 1, 2025, allowing time for implementation and compliance with the new regulations. This legislation reflects ongoing debates regarding the use of mRNA technology in vaccines, particularly in the context of public health and safety.
