Study Notes
Vaccines
- Vaccines are a primary method of disease prevention.
- They act as a first line of defense against bioterrorism.
- Globally, vaccines have shown significant success.
- Examples include smallpox, polio, and influenza.
- Vaccination rates are a critical public health measure for controlling outbreaks.
How Vaccines Work
- Vaccines stimulate immunity by introducing an agent.
- This triggers the body's immune system to form antibodies.
- The immune system acts like a watchdog, identifying and eliminating intruders (bacteria and viruses).
- The immune system distinguishes vaccine components from human cells.
- Immunity can be passive or active.
- Spacing between vaccine doses is crucial.
- Initial doses present lower antibody concentrations allowing slow production.
- Subsequent doses lead to quicker and more effective responses.
Immunity
- Active Immunity:
- Immunization introduces an agent or vaccine.
- The body creates antibodies.
- Provides long-term protection.
- Passive Immunity:
- Antibodies are received from another human or animal.
- Examples include immunoglobulins or antiserum.
- Maternal antibodies offer short-term protection.
- Lasts about 2 months, so vaccine schedules start after birth approximately*.
Herd Immunity
- Herd immunity involves a large portion of the community being vaccinated to prevent disease spread.
- A 95% vaccination rate is generally needed to protect the entire community.
- Reduced vulnerability to infections occurs in communities with high vaccination rates.
Two Main Types of Vaccines
- Inactivated Vaccines:
- Utilize whole or parts of microbes that are killed.
- Produce a weaker response than live vaccines, so booster shots are often needed.
- Side effects are typically minimal.
- Suitable for pregnant women or individuals with weak immune systems.
- Live Attenuated Vaccines:
- Grown from weakened live viruses.
- Often require only a single dose for life-long protection.
- Require cold chain systems for storage.
- Can occasionally cause a mild case of the disease.
Types of Inactivated and Live Attenuated Vaccines
- Inactivated: Includes Influenza, Polio(injected), Pertussis, Plague, Hepatitis A & B, Lyme Disease, Rabies
- Live Attenuated: Includes Measles, Mumps, Rubella, Chickenpox, Smallpox, Influenza(inhaled), Polio(oral)
mRNA Vaccines
- Messenger RNA (mRNA) vaccines instruct cells to produce proteins unique to a virus.
- These proteins trigger an immune response.
- mRNA vaccines destroy the virus's genetic material post-production.
- T-lymphocytes and B-lymphocytes are generated for future viral encounters.
- mRNA vaccines are a new technology based on decades of research.
Vaccine Additives & Production
- Antibiotics maintain vaccine sterility.
- Preservatives, like thimerosal, reduce contamination risks.
- Stabilizers prevent degradation from heat, light, etc.
- Silk-based additives are developed to reduce refrigeration need for vaccines.
Contraindications and Precautions
- Seizure after the first vaccine dose.
- Chronic renal disease.
- History of severe allergic reactions.
- Moderate to severe illness.
- Generalized malignancy.
- Immunosuppressive therapy.
- Recent blood or plasma transfusions.
Recommended Immunization Schedules
- Recommended schedules for child and adolescent vaccination provide the timing and dosages of vaccines.
- Catch-up schedules are available for individuals falling behind.
- Minimum intervals between doses are also important, with schedules outlined and catch-up options given.
Vaccines Recommended in Pregnancy
- Influenza.
- DTaP.
- COVID are recommended in pregnancy.
- Live vaccines are typically not recommended, as they are not suitable for pregnant individuals and should be avoided.
Outbreaks
- The presence of outbreaks highlights the importance of vaccination and public health efforts, with examples like measles outbreaks.
- COVID-19 and Measles were mentioned in this regard.
Vaccine Hesitancy
- The resistance to vaccination is influenced by cultural, philosophical, religious, and socioeconomic factors, as well as personal beliefs.
- Public health communication, education, and support can help reduce hesitancy.
Exemptions and Legislation
- Guidelines for vaccination exemptions and legislation vary from state to state and some countries.
- Religious protections and personal belief exemptions may exist in some regions.
- Understanding the legal ramifications regarding vaccination exemptions and requirements is important.
Percentage of US Adults that Required Vaccinations for Children
- The trend shows a decline in support for vaccine mandates between 1991 and 2019, based on US adult responses.
- Public sentiment towards vaccine mandates fluctuated over the past few decades, with varying levels of support and opposition to mandates through time.
Non-Medical Exemptions
- Non-medical exemptions for immunizations within schools should be closely monitored.
- Data from state-level exemption rates illustrates significant variations in exemption rates across regions.
States with the Lowest Vaccination Rates
- States demonstrate different levels of childhood vaccination rates.
- CDC studies show significant regional variations in vaccination rates as of 2021.
Who Delays and Refuses Vaccine
-
Reasons for delaying or refusing vaccines among parents include fears about side effects, the safety of vaccines themselves, concerns about the number of vaccines given, and trust in medical professionals.
-
Families of unvaccinated children tend to exhibit higher socioeconomic status (compared to families in lower socio-economic brackets).
Most Common Reasons for Requesting Alternative Vaccine Schedules
- The most frequent reason for requesting alternative vaccine schedules included a fear that vaccines would trigger autism spectrum disorder.
- Concerns also cited were the presence of added ingredients in vaccines or worries about added complications.
Vaccine Refusal or Alternative Schedules as of 2016
- Health care professionals reported that families were most likely to refuse or request alternative schedules for the HPV vaccine.
- Reports show significant resistance towards the MMR, Hepatitis A and B vaccines, as well as others.
Disadvantage of Vaccinations for Children
- The percentage of US adults who were aware of the disadvantages of vaccinations for children steadily increased between 2001 and 2019.
- Discomfort regarding the possible negative side effects of vaccinations for children has significantly increased in recent decades.
Vaccine Messaging
- Anti-vaccine messaging on social media surged during the pandemic.
- Controversial figures disseminated misinformation about vaccines, contributing to the spread of misinformation.
- Misinformation and spread of false or misleading statistics and videos are significant issues to consider when promoting child vaccination.
Common Vaccine Myths
- Misconceptions surrounding vaccine safety, immune system capacity, cause of diseases from vaccines, and vaccine composition exist.
- Such myths present a challenge to public health objectives, highlighting the importance of correct information, credible sources and effective communication strategies to correct these inaccuracies.
