Study Notes
Collaboration with Pediatricians
- Collaboration with pediatricians is essential in optimizing immunization delivery and ensuring comprehensive care for children.
U.S. Healthcare Personnel Vaccination Rates (2020-2021)
- Overall healthcare personnel vaccination rate for influenza: 91.3%
- Physicians: 88.9%
- Nurse Practitioners/Physician Assistants: 90.3%
- Nurses: 90.3%
- Pharmacists: 83.0%
- Other clinical personnel: 75.9%
Immune Response Overview
- Immune response consists of innate immunity and acquired (adaptive) immunity.
- Acquired immunity activates through exposure to antigens, leading to the production of antibodies.
Vaccines and the Immune Response
- Vaccines contain antigens that provoke an immune response.
- Activation of B cells leads to antibody production, which targets and destroys antigens.
- Memory B cells and T cells are formed for future immunity.
Types of Vaccines
- Live Attenuated Vaccines: Made from viruses or bacteria, require replication to stimulate an immune response.
- Inactivated Vaccines: Contain non-replicating virus or bacteria; may include adjuvants to boost immune response.
Considerations for Live vs. Inactivated Vaccines
- Storage: Varies between vaccine types.
- Dosing Schedule: Timing of doses differs.
- Duration of Protection: Live vaccines often provide longer protection.
- Adverse Effects and Precautions: Different profiles for each type.
- Route of Administration: Varies based on vaccine type.
Minimum Intervals Between Vaccines
- No minimum for two inactivated vaccines or inactivated with live vaccines.
- Live vaccines: 28-day minimum interval if not administered simultaneously.
Contraindications to Vaccination
- Severe allergies (anaphylaxis) to vaccine components are universal contraindications.
- Minor illnesses (e.g., mild fever) typically do not preclude vaccination unless the patient is severely ill.
Vaccination in Special Populations: Pregnancy
- Vaccination before pregnancy is encouraged.
- Inactivated influenza vaccine is recommended during pregnancy.
- Tdap vaccine should be administered in the early part of the gestational weeks 27-36.
- Avoid live vaccines during pregnancy.
Vaccination and Immunosuppressed Patients
- Timing and type of vaccination depend on the level of immunosuppression.
- Live vaccines pose heightened risk, while inactivated vaccines may have reduced effectiveness.
Pneumococcal Vaccines
- PCV13: Approved for ages 6 weeks and older. Routine schedule includes doses at 2, 4, 6, 12 to 15 months.
- PCV15: Approved for adults and recommended for people over 65 or with certain health conditions.
- Pneumococcal Recommendations: Follow CDC guidelines for administering to both children and adults.
Rotavirus Vaccines
- RotaTeq: 3 doses at 2, 4, and 6 months.
- Rotarix: 2 doses at 2 and 4 months.
- Contraindicated in children with gastrointestinal problems or certain immunodeficiencies.
COVID-19 Vaccination Guidelines
- Primary vaccination series for Pfizer-BioNTech and Moderna consists of two doses spaced apart, with additional doses for immunocompromised individuals.
- Boosters: Recommended for individuals 18 and older at specified intervals after the primary series.
Monovalent vs. Bivalent Vaccines
- Clarification on the differences between monovalent and bivalent vaccines relating to COVID-19 vaccination strategies may be necessary.
