PREVEXXION® RN
The future is now
PREVEXXION® RN is a biological tool effective against very virulent strains of Marek’s disease (MD). The vaccine contains a frozen MD chimera consisting of three serotype1 strains. Since MD maintains a constant pressure on farms, keeping the disease under control through vaccination is critical.1
Key Advantages
- Proprietary attenuation process delivers the right balance between safety2 & efficacy2
- Provides protection against very virulent MD virus
- Unprecedented and controlled attenuation process for a Marek’s disease (MD) strain that results from different MD virus and LTR gene sequence insertions
- Administration in ovo or at day-old
- Compatible with other MD vaccines for a customized vaccination program
- Same convenient application as classic MD vaccines
- No reversion to virulence3
- Packaged in 5 x 2,000 dose ampules in frozen presentation
- Do not vaccinate diseased embryonated eggs or birds
- Administer a full dose to each embryonated egg or to each bird
- Vaccinate all birds on the premises at one time
- Avoid stress conditions during and following vaccination
- Do not place chickens in contaminated facilities
