Boehringer to stay focused on porcine type 2 vaccine; dropping its RTU program

Boehringer Ingelheim said it will end research into developing a porcine circovirus type 2 ready-to-use (RTU) vaccine combination to focus its attention on its PCV2 Mycoplasma hyopneumoniae (M. hyo) vaccine.

The company said its research program found that the best protection against both pathogens was found in its vaccines when freshly mixed and used as recommended. Although early data showed promise, the RTU combination didn't reach company standards for efficacy and safety.

Boehringer's FLEXcombo platform of mixable vaccines protects pigs against both PCV2 and M. hyo in a single dose. Its MycoFLEX headspace bottle, which was introduced last year, allows farmers to mix the two pig vaccines for a single application.

The same concept is used for several other of the company's animal pharmaceuticals and is licensed in North America and several Asian countries.
