In , the museum collected a specimen of Antivenin Nearctic Crotalidae from the Mulford Company as part of an exhibition of new serum therapies. Antivenom was an exciting new technology that offered hope in the face of a common human fear.

By this time, the H. Mulford Company offered two additional varieties of snake antivenom. The first, Antivenin Bothropic, was another polyvalent antivenom created to neutralize the venom of South American pit vipers of the genus Bothrops.

Bites from these snakes kill more people in the Americas than any other venomous snake. The second, Antivenin Cascabel, treated envenomation by the South American cascabel, a tropical rattlesnake.

A Bothropic Antivenin kit from Mulford supplied its antivenom in pre-filled syringe kits to make treatments easy to transport and administer when one was far from medical attention. Even better, a companion could inject you in the arm or between the shoulder blades.

Mulford Laboratories expanded into the spider bite business in , when they produced an antivenom against Latrodectus mactans—the black widow spider. In the past few years, snakebite antivenom has been in the news, again.

In states such as Texas and Florida, a shortage of coral snake antivenom has put medical providers in a disturbing position. Because they do not want to waste the precious treatment, some doctors feel pressured to wait and see if a bite-victim shows symptoms of envenomation before administering antivenom.

However, the power of the treatment can be compromised by waiting. Although the World Health Organization includes snakebite antivenom on its List of Essential Medicines, the world is experiencing shortages of antivenom.

The populations hardest hit by the shortages tend to live and work in rural areas where highly venomous snakes are endemic, especially in less-developed nations with housing that allows for easier access by venomous snakes.

Hospitals currently face a multifaceted antivenom problem. Antivenom can be very expensive, a problem that is compounded when the product goes unused before its expiration date. Many clinics do not have sufficient training in selecting the correct antivenom or administering the treatment. The challenges do not stop there: patients can suffer serious allergic reactions to antivenom, and medical supervision during treatment is important.

New monoclonal antibody antivenoms that cause fewer allergic reactions are being developed. However, because the CroFab product uses only a fragment of the cultured antibody, it causes fewer serious allergic reactions than older serum-based, whole antibody antivenoms.

Antivenom is one of those treatments that most of us never think about—until we suddenly and very desperately need it. Contemporary antivenoms made under strict controls are very effective. Yet, they remain out of reach for many victims who most need them. The Antibody Initiative Antivenom.
