Study Notes
Vaccination Guidelines
- Vaccination timing can vary based on immune globulin (IG) administration; delay vaccines by up to 11 months post-IG to avoid immune suppression effects.
- Initial vaccinations are given at birth as part of routine immunization schedules.
- In KSA, four doses of vaccines are provided to reduce disease incidence and prevalence.
- Vaccines are not given to infants weighing less than 2 kg.
Vaccination Schedule and Types
- Specific vaccination schedules must be followed for accurate immunity development, e.g., measles vaccination at 9 months and MMR at 1 year with additional boosters at 18 months.
- Haemophilus influenzae type B vaccine is critical in preventing meningitis; administered in three doses at 2, 4, and 6 months.
- Oral Polio Vaccine is cost-effective but contraindicated for immunocompromised individuals.
Vaccine Reactions and Contraindications
- Monitor for severe allergic reactions (e.g., anaphylaxis) after vaccination; previous reactions may prevent future doses.
- Imunocompromised patients should avoid live vaccines (e.g., BCG, OPV, MMR, Varicella).
- Vaccination rescheduling may occur until the patient's health is stable.
Specific Vaccines
- Tetanus vaccine is crucial for adults and healthcare workers to prevent tetanus; consider periodic boosters every 10 years.
- Pneumococcal vaccines (conjugate and polysaccharide types) provide immunity against various strains, but polysaccharide vaccines are typically re-administered every 2-3 years.
- The BCG vaccine is administered intradermally and is essential for tuberculosis prevention.
General Recommendations
- Healthcare workers and individuals in contact with animals should receive specific vaccinations like rabies and meningococcal.
- The schedule and timing of doses are critical; for instance, injectable polio vaccines are given at 2, 4, and 6 months of age.
- All infants, regardless of being born preterm, should follow the same vaccination guidelines once they meet weight requirements.
Key Considerations
- Vaccines must be administered following established protocols to minimize risks and maximize immunity.
- Certain vaccines may require adjustments based on an infant's weight, age, or previous medical history, particularly in cases of immunosuppression.
- All vaccination doses should be given within recommended timelines to ensure optimal effectiveness and protection against diseases.
