annually

3. Immunization Schedule for HCP
Vaccine Indication Schedule
MMR Adults born after 1957 with no proof of
immunity:
•documented vaccination with 2 doses
•laboratory evidence of immunity
•laboratory confirmation of disease
2doses of 0.5 mL SC
at 0 & at least 1 month

2doses of 0.5 mL SC
at time 0 weeks & 4-8

5. Influenza Vaccination
 HCP must receive the vaccine or sign a declination after
reading the benefits of receiving vaccine versus risks to self,
patients and others by not receiving the vaccine.
 If HCP refuses the influenza vaccine, it is mandatory that HCP
wear a barrier mask during influenza season when providing
direct patient care.
 Methods increasing vaccination rates:
– Monetary incentive to receive the vaccine.
– Providing the vaccine at convenient times and locations.
– Receiving the vaccine as a condition of employment.

6. Influenza Vaccination
 Vaccination against influenza is recommended for all HCP.
 It takes about 2 weeks after vaccination for antibodies to
develop that protect against influenza virus infection.
 Vaccines can be offered from September to March.
 Inactivated trivalent vaccine (TIV(:
– > 6 months old (healthy people, chronic medical conditions(
– One dose of 0.5 mL IM annually

7. Influenza Vaccination
 Live attenuated influenza vaccine (LAIV(:
– Healthy people 2 to 49 years of age who are not pregnant
– Intranasal dose of 0.2 ml annually
 Avoid use of LAIV among HCP or other close contacts of
severely immunocompromised persons.
 HCP who receive LAIV should not provide care for severely
immune-suppressed patients for 7 days after vaccination.

8. Influenza Vaccination
If influenza outbreak occurs, unvaccinated staff should be re-
offered influenza vaccinations
If an outbreak is caused by a strain of influenza virus that is not
well matched by the vaccine for that season, chemoprophylaxis
should be considered for all employees, regardless of their
vaccination status.

16. WHERE?

17. Post Exposure Management
 Varicella
 Meningococcal Disease
 MMR
 Pertussis
 TB
 Blood borne pathogens

18. Varicella Post Exposure Management
Unvaccinated susceptible personnel exposed to varicella:
Exclude the person from duty from the 10th day after exposure
through the 21st day after exposure or until all lesions are dry and
crusted if varicella occurs.
Vaccinated personnel exposed to varicella:
Serological testing immediately after exposure to assess the
presence of antibody.
If seronegative, exclude the person from duty from day 10 through day
21 postexposure.
If fever, URT symptoms, or rash develop, then exclude the person from
duty until all lesions are dry and crusted

19. Varicella Post Exposure Management
 Consider administering the vaccination for exposed
unvaccinated personnel without documented immunity. The
efficacy of postexposure vaccination is unknown.
 VZIG use is considered for immunocompromised or pregnant
workers postexposure.
 If VZIG is used, extend the time that the worker is excluded
from duty from 21 days to 28 days postexposure.

20. Meningococcal Disease Post Exposure
Management
 Exposed personnel do not need to be excluded from duty.
 PEP is advised for persons who have had intensive, unprotected
contact with infected patients.
 Unprotected means without wearing a mask
 Intensive contact include:
– mouth-to-mouth resuscitation
– endotracheal intubation
– endotracheal tube management or
– close examination of the oropharynx

21. Meningococcal Disease Post Exposure
Management
 Prophylactic therapy should be administered immediately after
the unprotected exposure.
 Current recommended regimens:
– Rifampin 600 mg PO BID for 2 days
– Single dose of ciprofloxacin 500 mg PO or
– Single dose of ceftriaxone 250 mg IM.
 Rifampin & ciprofloxacin are not recommended for pregnant
women.

22. MMR Post Exposure Management
Measles vaccine should be administered to susceptible HCP
who have had contact with a measles patient within 3 days of the
exposure (or IG within 6 days of exposure) to modify severity of
infection
Mumps vaccine and IG are not proven to prevent infection after
exposure.
Rubella vaccine and IG are not proven to prevent infection after
exposure.

23. MMR Post Exposure Management
 Susceptible personnel who are exposed to measles need to be
excluded from duty 5 days after the first exposure to 21 days
after the last exposure.
 Susceptible personnel who are exposed to mumps need to be
excluded from duty the 9th
day after the first exposure to the 26th
day after the last exposure.
 Susceptible personnel who are exposed to rubella need to be
excluded from duty from the 7th
day after the first exposure
through the 21st
day after the last exposure.

24. Pertussis Post Exposure Management
 PEP is indicated for personnel exposed to pertussis.
 The regimen used is either:
– Erythromycin 500 mg QID 14 days
– One tab of trimethoprim-sulfamethoxazole BID 14 days
 Exposed personnel do not need to be excluded from duty.
 Personnel in whom symptoms develop should be excluded until
5 days after the start of appropriate therapy.
