The Texas Senate is debating a bill that would ban the use of the life-saving immunoglobulin (Ig) beta-1 antibody during the upcoming recess.
Texas Sen. Joe Straus (R) introduced the bill after his children were hospitalized in January for a rare allergic reaction.
His son, a student at Austin’s Trinity College, had been given the anti-retroviral drug AZT.
Greg Abbott (R), a Republican, has said the bill is needed because of a “record number of hospitalizations” and because of the high rate of death among the state’s newborns.
Straus said he hopes the bill will become law.
The Texas Tribune reported that it was introduced by Sen. Rodney Ellis (R-Houston) and Rep. Joaquin Castro (D-Houston).
Straus and Ellis have both expressed support for the legislation.
The House voted to send the bill to the Senate on Thursday.
Straus, a longtime ally of Abbott, has been pushing for the bill for years.
Cruz, the Texas Republican who is in the Senate, has not yet made a decision on the bill.
