Vaccination plays a crucial role in maintaining the health and productivity of pigeons. Pharmavac Columbi 2 is a vaccine specifically designed to provide active immunization against paramyxovirus type 1 and pigeon herpes virus infections.

Active Ingredients and Composition

Pharmavac Columbi 2 contains two main active substances that help stimulate the pigeon’s immune response:

1. Paramyxovirus Type 1 (Strain La Sota): Each 0.3 ml dose contains a minimum of 7 log2 haemagglutination-inhibition (HI) antibodies. This indicates the vaccine’s effectiveness in inducing an immune response in vaccinated pigeons.

2. Pigeon Herpes Virus (Strain V298/70): This component has a minimum of 1 log2 virus-neutralization (VN) antibodies, ensuring protection against viral infections specific to pigeons.

In addition to the active ingredients, Pharmavac Columbi 2 includes excipients such as formaldehyde, thiomersal, and an oil emulsion, which help stabilize the vaccine and enhance its efficacy.

Therapeutic Indications: Immunization Against Viral Infections

Pharmavac Columbi 2 is indicated for the active immunization of pigeons against two critical viral infections:

Paramyxovirus Type 1: This virus is highly contagious among pigeon populations and can lead to severe neurological conditions. Vaccination helps prevent outbreaks and protects flock health.

Pigeon Herpes Viru: Another serious virus affecting pigeons, it can lead to respiratory symptoms and reduced performance in affected birds. The vaccine effectively reduces the susceptibility to these viral infections.

The onset of immunity is evident 14 days after the last injection, while the duration of immunity lasts for one year. Therefore, appropriate vaccination timelines are critical for ensuring ongoing protection against these viruses.

Dosage, Administration, and Revaccination Schedule

The recommended dose of Pharmavac Columbi 2 is 0.3 ml, administered subcutaneously (in the neck) or intramuscularly (in the chest or thigh muscles). The vaccination protocol is as follows:

Young Animals: Initial vaccination is essential to stimulate the immune response. Vaccination typically occurs prior to the laying period to ensure that the antibody transfer to offspring occurs via the eggs.

Revaccination: For optimal protection, revaccination should occur every 3 to 5 weeks. Adults in an endangered breeding environment should be vaccinated twice a year, ideally at intervals of six months.
