What are measles parties? Dr. Ron Cook, chief health officer at Texas Tech University Health Center Sciences said in a virtual press conference Friday measles parties as of late have “mostly been social media talk.

U.S. Health Secretary Robert F. Kennedy Jr. said last week he would send Texas 2,000 doses of the measles, mumps and rubella vaccine through its immunization program. Kennedy founded the anti-vaccine group Children’s Health Defense, but has said he would not prevent Americans from getting vaccinated.

The warning against measles parties comes days after an unvaccinated child died of measles in Lubbock County about month after an outbreak began in West Texas.
