Tess, the beloved, 40-year-old matriarch of the Houston Zoo’s elephant herd, is recovering well after receiving the first-ever mRNA vaccine against elephant endotheliotropic herpesvirus (EEHV) 1A on Tuesday, June 18. The veterinary staff at the Houston Zoo will monitor Tess in the coming weeks to check her reaction and the efficacy of the vaccine.

EEHV 1A is a deadly infection for Asian Elephants. While generally benign in African Elephants, Asian Elephants can develop fatal hemorrhages. The fatality rate is a whopping 80 percent, making it one of the most serous threats to elephant populations outside of humans.

Anti-viral drugs have some effect on the disease, but two-thirds show no improvement. This has led to a search for a vaccine. For 15 years, the Houston Zoo and Dr. Paul Ling at Baylor College of Medicine’s Department of Virology and Microbiology have partnered to develop the drug. They have been helped by worldwide research from zoos and animal specialists, as well as graduate student Jessica Watts and Dr. Jeroen Pollet at Houston's Texas Children’s Hospital. The research has been funded by private donations, research partnerships, and grants.

Before being inoculated, the mRNA vaccine was exhaustively tested, with the dosage being extrapolated from data involving horses.

Houston Zoo veterinarians will periodically test Tess to see if she is developing the appropriate antibodies. If she is and there are no adverse reactions, the next step will be to administer the vaccine to the rest of the Houston herd. Many of these are Tess’s own children (Tucker, Tupelo, Tilly, and Teddy) and grandchildren (Winnie).

Should the vaccine prove effective, the doses will be made available worldwide to zoos and private elephant sanctuaries. It is likely to have a significant benefit on protecting and preserving the Asian Elephant population. As of January, there are fewer than 50,000 of the animas left in the wild. They are currently listed as endangered, and breeding programs and research done through the Houston Zoo are essential to keeping the animals from going extinct.

Houston Livestock Show and Rodeo commits over $30 million to education

The money supports studies in fields such as animal husbandry.

The Houston Livestock Show and Rodeo continues its annual tradition of breaking its own record when it comes to educational endowments. On Giving Tuesday, the organization pledged to disburse $30,353,380 in 2026 in the form of scholarships, grants, and other funding.

“This milestone moment of reaching $30 million in a single year highlights the Rodeo’s unwavering dedication to Texas youth and education,” HLSR president and CEO Chris Boleman said in a statement. “Thanks to our loyal donors, sponsors, more than 36,000 volunteers and dedicated attendees, 2026 will reach historic heights in supporting the next generation of leaders, agricultural professionals and organizations that share the Rodeo’s mission.”

This brings the total of education funding provided by the Rodeo since 1932 up to $660 million. Last year's $28 million commitment also set a new record.

One innovation this year is the establishment of the Area Go Texan Vocational Scholarship, a program that expands on the relationship with 68 Texas counties through the Area Go Texan affiliate program. One student from each county will receive $6,000 toward a degree or certificate in a vocational field at a Texas nonprofit college or university. Another $500,000 in vocational scholarships will awarded to 10 schools in 2026. Guidelines for applying can be found at this link.

In total, the Rodeo will hand out $15,126,000 in scholarships, $11,273,500 to junior exhibitors, $3,430,880 in grants, and $523,000 in graduate assistantships. Grants will be awarded to 82 Texas institutions and organizations, such as Arts for Rural Texas, BridgeYear, The Bryan Museum, Diversity in the Arts and Entertainment, Greater Houston Partnership Foundation, Multicultural Education and Counseling through the Arts (MECA), Space Center Houston, Texas State University Development Foundation, and University of St. Thomas at Houston.

Money for the annual endowment is raised through the annual auctions, sales of livestock and art, and through charitable donations. The goal of the endowment program is to promote study and research in agriculture, animal husbandry, and other fields that directly benefit the Rodeo.

The Rodeo is scheduled to run from March 2 – 22, 2026. More information on performers, attractions, and vendors can be found at RodeoHouston.com. Scholarship applications are open through February 2, with funds being awarded in summer 2026.
