What types of immunizations may first responders be required to have?

Immunization Recommendations for Disaster Responders

• Hepatitis A vaccine (low probability of exposure).
• Typhoid vaccine (low probability of exposure).
• Cholera vaccine (low probability of exposure, no licensed cholera vaccine available in the U.S.).

What is the difference between primary and secondary vaccine failure?

Primary vaccine failure could be defined as the failure to seroconvert or the failure to mount a protective immune response after vaccination despite seroconversion, whereas secondary vaccine failure is the gradual waning of immunity over time.

What can cause a vaccine to not work?

There are two main reasons for failure of immunizations: (1) failure of the vaccine delivery system to provide potent vaccines properly to persons in need; and (2) failure of the immune response, whether due to inadequacies of the vaccine or factors inherent in the host.

How common is immunity to Hep B?

All subjects responded with anti-HBs (mean titer, 143 mIU/mL). The duration of immunity after vaccination against HBV is not known. Ten percent of the patients who receive and respond to vaccination lose anti-HBs after 5 years and 50% lose anti-HBs after 10 years.

Can you get Hep B even if vaccinated?

Can I get hepatitis B from being vaccinated? No. The hepatitis B vaccine does not contain any live virus and can’t cause hepatitis B.
