Q

What is the recommended screening for immigrants?

A

Hep B (Africa, Asia, Eastern Europe and parts of South America)
Vaccinate susceptible, refer chronic infection for treatment (and consider screen HCC as indicated)
Hep C (specifically subSaharan Africa [10%]; eastern Europe, especially Uzbekistan and Tajikistan [27%]; Egypt [25%–50%]; Vietnam [10%]; and Pakistan [5-35%]) and exposure to contaminated blood, usually as nosocomial transmission through unscreened blood products, surgery or receipt of intramuscular injections)
If positive, vaccinate Hep A/B, limit alcohol and refer for treatment
TB PPD skin test (Sub-Saharan Africa, Asia, and Central and South America, and some in Eastern Europe)
CXR to rule out active disease
HIV (sub-Saharan Africa, Caribbean, Thailand)
Post-test counselling and refer to HIV treatment program
Intestinal parasites if from endemic area, compatible sign/symptoms of infection (asthma) or evidence of peripheral eosinophilia
Strongyloides serology (consider in immigrants from Southeast Asia and Africa)
If positive, treat with ivermectin (or albendazole)
Shistosomiasis serology (Africa)
If positive, treat with praziquantel
DM2 >35yo South Asian, Latin American and African
Iron-deficiency anemia with hemoglobin for women of reproductive age, and children 1-4yo
Dental disease (ask all if any pain, and look for evidence of disease)
Refer to dentist (and treat pain with NSAID)

Guillain-Barre syndrome) upon administration of previous dose of a particular vaccine Anaphylactic reaction or other serious reaction to a component of a vaccine (eg. egg, gelatin, latex, neomycin, thimerosal) Pregnant or immunocompromised/suppressed, active TB should not receive LIVE vaccines (BCG, Zostavax, LAIV, MMRV, rotavirus, Smallpox Typhoid [oral], Yellow fever) Consider delaying inactivated vaccines 1-3 months after immunosuppressive therapy

Uncorrected congenital malformation of GI tract Previous intussusception

39
When you should think about vaccinations
In infancy Before pregnancy Before traveling When new to the country if not previously immunized
40
Vaccine fears - how to approach fears about SE
Most common side effects are mild fever and sore extremity. Serious reactions (death, encephalopathy) are so rare that their incidence cannot be calculated.
41
Vaccine hesitancy - how to approach fears about autism
The original paper in the Lancet publishing this association was recently withdrawn and there have been no definitive cases to support this claim. This was originally associated with a preservative agent called thimerosal. The only vaccines in Canada that are given to children and contain thimerosal are the multidose influenza vaccine and Hepatitis B. Both these vaccinations are available in formulations that do not contain thimerosal (ex. Vaxigrip for children and pregnant mothers). The only true contraindication to thimerosal is anaphylaxis.
42
Vaccine hesitancy - how to approach fears about vaccines not working
No vaccine is entirely effective. If a vaccine-preventable disease outbreak does occur, some vaccinated individuals will contract the disease. However the proportion of unvaccinated individuals who contract the disease will be much higher than the proportion of vaccinated individuals.
43
Vaccine hesitancy - how to approach people that say vaccine preventable diseases no longer exist
Certainly some vaccine-preventable diseases are rarely, if ever, seen in Canada and herd immunity for unvaccinated individuals does occur. However, unvaccinated individuals may still be exposed in their lifetime given the immigrant population that may not have been vaccinated or if the unvaccinated chooses to travel later in life.
44
Vax in premature babies
Premature infants should receive immunizations at the same time (chronological age) as term infants, ie. do not delay vaccinations - in Quebec first vaccines at 2 months old Exception: In jurisdictions where Hep B vaccine is given at birth in HbsAg negative mother, delay until infant 2000g or discharged from hospital
45
Vax for asplenia/ hyposplenia
Pneumococcal (most common infection in asplenia) Meningococcal Haemophilus Influenza Type B Influenza Hep A and B if repeated transfusions
46
Vax for chronic liver disease
Hepatitis A and B Influenza +/- Pneumococal
47
Who gets pneumococcal
≥65yo, <65 with specific risk factor
48
Who gets herpes zoster
≥60yo (consider 50-59yo), immunosuppressed Live attenuated (Zostavax) vs. Non-live recombinant adjuvanted (Shingrix) 1 dose vs. 2 doses (2 months apart) Herpes Zoster relative risk reduction 51% (NNT 59) vs. 97% (NNT 37) Post-herpetic neuralgia RR reduction 67% (NNT 364) vs. 89% Adults ≥50yo who are known VZV seronegative should be given univalent varicella vaccine rather than herpes zoster (routine testing not recommended)
49
Who gets HPV
9-26yo and ≥27yo who are at ongoing risk PIQ recommends vaccinating women 9-45yo, men 9-26yo even if previous HPV exposure
50
Who gets meningococcal
Up to 24yo not immunized, or risk
51

prev anaphylaxis or allergy
