NOBIVAC RABIES VACCINE (INACTIVATED RABIES STRAIN PASTEUR RIV)(2IU/ML)

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

• Rabies prevention
• Anthrax prevention
• Diphtheria prevention
• Tetanus prevention
• Typhoid fever prevention

Dosage

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

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

Mechanism of action

Vaccines like those developed by Pasteur work by introducing a harmless component or inactivated form of the pathogen into the body, prompting an immune response. This response includes the production of antibodies and the activation of T-cells that can recognize and attack the pathogen if encountered in the future.

Pharmacodynamics

The pharmacodynamics of Pasteur's vaccines involves the stimulation and enhancement of the immune system. Upon administration, the body recognizes the vaccine antigens, leading to the activation of both humoral and cellular immune responses. This results in the production of specific antibodies and memory cells that provide long-term immunity against the disease.

Pharmacokinetics

The pharmacokinetics of vaccines involves the distribution, metabolism, and excretion of the vaccine components. Once administered, the vaccine components are taken up by antigen-presenting cells, which process and present the antigens to T-cells. The immune response typically peaks within a few weeks, with memory cells persisting for months to years, depending on the vaccine.

Pregnancy

Not enough evidence to establish safety during pregnancy. Consult healthcare professionals before use.

Breast-feeding

Limited data available. Consult a healthcare professional before use during breastfeeding.

Storage

Store in a cool, dry place, away from direct sunlight. Follow specific product storage instructions if available.

Indications

• Rabies prevention in individuals at high risk of exposure
• Post-exposure prophylaxis following potential rabies exposure
• Vaccination for travelers to endemic regions

Dosage

Children: Refer to the BNF for Children for specific dosing recommendations for pediatric patients.

Adults: Refer to the BNF for specific dosing guidelines, as it varies based on exposure risk and vaccination history.

Mechanism of action

The rabies vaccine works by stimulating the immune system to produce antibodies against the rabies virus. This is achieved through the introduction of inactivated or attenuated virus particles, which mimic the infection without causing the disease. The immune response generated helps to prevent the virus from causing illness upon subsequent exposure.

Pharmacodynamics

The rabies vaccine induces an adaptive immune response, leading to the production of neutralizing antibodies specific to the rabies virus. This immune memory protects against future infections. The vaccine is typically administered in a series of doses to ensure adequate immune response and long-term protection.

Pharmacokinetics

The pharmacokinetics of the rabies vaccine involve absorption at the injection site, followed by systemic distribution of the antigens. The onset of immunity generally occurs within two weeks after the initial vaccination, with peak antibody levels typically reached within one to two months. The duration of immunity can vary, necessitating booster doses in certain populations.

Interactions

• chloroquine+rabiesvaccine: Severe (decreases efficacy)

Pregnancy

Rabies vaccination is generally considered safe during pregnancy. However, the risks and benefits should be carefully evaluated.

Breast-feeding

Rabies vaccine is not known to cause any adverse effects in breastfeeding. However, consult with a healthcare provider for individual assessments.

Storage

Store the rabies vaccine in a refrigerator at 2-8 degrees Celsius. Do not freeze.

Indications

• Bacterial infections
• Viral infections
• Epidemiological studies
• Antibiotic resistance monitoring

Dosage

Children: Refer to specific antimicrobial treatment guidelines based on the strain identified and the infection site.

Adults: Refer to specific antimicrobial treatment guidelines based on the strain identified and the infection site.

Mechanism of action

The mechanism of action for a strain depends on the type of microorganism it represents. For pathogenic bacteria, the strain may produce toxins, evade the host's immune response, or possess resistance mechanisms that allow it to survive in the presence of antibiotics. For viruses, strains may exhibit mutations that alter their ability to infect host cells or evade antiviral therapies.

Pharmacodynamics

Pharmacodynamics in the context of strains involves the interaction between the strain and the host's immune system, as well as the effects of specific antimicrobial agents on the strain. These interactions can influence the efficacy of treatments and the development of resistance.

Pharmacokinetics

Pharmacokinetics is not directly applicable to strains themselves but rather to the drugs used to treat infections caused by specific strains. Factors such as absorption, distribution, metabolism, and excretion of antimicrobial agents can vary depending on the strain's characteristics and the site of infection.

Pregnancy

There is limited information on the safety of strain in pregnancy. It is advisable to consult healthcare professionals for guidance.

Breast-feeding

Safety during breastfeeding is not well established. It is recommended to seek medical advice before use.

Storage

Store in a cool, dry place, away from direct sunlight and moisture. Keep out of reach of children.
