AQUAVAC IRIDOV (INACTIVATED IRIDOVIRUS) PER ML 2 X 107 TCID50 OF INACTIVATED IRIDOVIRUS

Indications

• Hepatitis A
• Hepatitis B
• Influenza
• Polio
• Rabies
• Typhoid fever

Dosage

Children: Refer to specific product guidelines for paediatric dosing, as it varies by vaccine type and indication.

Adults: Refer to specific product guidelines for adult dosing, as it varies by vaccine type and indication.

Mechanism of action

Inactivated vaccines work by introducing a form of the pathogen that cannot cause disease into the body. This stimulates the immune system to produce antibodies and memory cells specific to the pathogen, allowing for a robust immune response upon future exposure. The immune system recognizes the inactivated pathogen as foreign, leading to the activation of T-cells and B-cells, which are crucial for long-term immunity.

Pharmacodynamics

The pharmacodynamics of inactivated vaccines involve the generation of an adaptive immune response. After vaccination, the body produces specific antibodies against the inactivated pathogen. The response typically includes both humoral immunity, characterized by antibody production, and cellular immunity, involving T-cell activation. The duration of immunity can vary, and booster doses may be required to maintain adequate protection.

Pharmacokinetics

Inactivated vaccines do not have a pharmacokinetic profile like traditional drugs since they do not enter systemic circulation in the same manner. Following administration, the vaccine components are taken up by antigen-presenting cells, which process and present the antigens to T-cells. The immune response is initiated locally at the site of injection and can be influenced by factors such as the route of administration and the presence of adjuvants that enhance the immune response.

Adverse effects

• Injection site reactions (pain, swelling, redness)
• Fever
• Fatigue
• Headache
• Myalgia
• Chills

Precautions

• Assess for allergies to vaccine components
• Monitor for allergic reactions post-administration
• Consider underlying health conditions that may affect immune response

Pregnancy

Inactivated vaccines are generally considered safe during pregnancy, but individual risk-benefit assessment is recommended.

Breast-feeding

Inactivated vaccines can be administered during breastfeeding without concern for adverse effects in the infant.

Storage

Store in a refrigerator at 2°C to 8°C. Do not freeze.

Formulations

• Inactivated viral vaccines
• Inactivated bacterial vaccines

Indications

• Iridovirus infections in fish
• Irradiated viral diseases in aquaculture
• Management of viral outbreaks in aquatic environments

Dosage

Children: Refer to specific antiviral agent guidelines as there is no standardized dosage for iridovirus.

Adults: Refer to specific antiviral agent guidelines as there is no standardized dosage for iridovirus.

Mechanism of action

Iridoviruses replicate within the host's cells by utilizing the host's cellular machinery for viral DNA synthesis and protein translation. They disrupt normal cellular functions, leading to cell death and the manifestation of disease symptoms. The viruses can evade the host's immune response by various mechanisms, including inhibiting apoptosis and modulating immune responses.

Pharmacodynamics

The pharmacodynamics of antiviral agents targeting iridoviruses often focus on inhibiting viral replication or enhancing the host's immune response. Drugs may act by interfering with viral DNA synthesis or preventing the assembly and release of new viral particles. The effectiveness of treatment can vary based on the specific virus strain and the host's condition.

Pharmacokinetics

The pharmacokinetics of iridovirus treatments largely depend on the specific antiviral agents used, as there is no direct pharmacological treatment for iridovirus infections. Generally, antiviral agents will have varying absorption, distribution, metabolism, and excretion profiles based on their chemical properties. Studies on pharmacokinetics in aquatic animals are limited, but factors such as water temperature, salinity, and the host's metabolic rate can influence drug behavior.

Pregnancy

There is insufficient data on the effects of iridovirus infection during pregnancy. Pregnant individuals should be cautious and consult healthcare providers for guidance.

Breast-feeding

The safety of iridovirus during breastfeeding is not well established. It is advisable for breastfeeding individuals to speak with a healthcare professional before exposure.

Storage

Iridovirus should be stored in a cool, dry place away from direct sunlight and moisture. Specific storage conditions may depend on the formulation used.
