Primovaccinatie met dTp(a) ? In de bijsluiter wordt de primovaccinatiemet het dTp(a)-vaccin niet vermeld.Ook de aanbeveling van de HogeGezondheidsraad vermelden daaroverniets.Een studie uit 2007 onderzocht bijvolwassenen ouder dan 40 jaar die devoorbije 20 jaar geen tetanus of difterievaccinhadden gekregen of waarvan devaccinatiestatus onbekend was, de efficiëntievan dTp(a) en dTp(a)-IPV-vaccins.Eén maand na de toediening van 3 dosissen,bedroeg het niveau van beschermendeantistoffen 99%. Bij gebrek aan dT kan dTp(a) dus worden gebruikt voor primovaccinatie. Indien ook bescherming tegen polio nodig is, kan dTp(a)-IPV gebruikt worden

Primovaccination avec le dTp(a) ?

Ni la notice, ni les recommandations duConseil Supérieur de la Santé ne mentionnentla possibilité d’une primovaccinationavec le dTp(a).Cependant, une étude publiée en2007 a montré chez 99% des vaccinésl’obtention de taux séroprotecteurscontre le tétanos et la diphtérie après uneprimovaccination à l’aide du dTp(a) (3doses), chez des adultes de plus de 40ans (en absence de données vaccinalesou avec un dernier rappel datant de plusde 20 ans).En cas d’indisponibilté du dT, par exemple lors d’une rupture de stock, l’administration du dTp(a) pourrait donc être utilisé en primovaccination. En cas de nécessité d’une protection contre la poliomyélite, dTp(a)-IPV peut être utilisé,

Extract from CatMat 2014 = Canadian guidelines

The strongest and most consistent predictor of typhoid risk in travellers is destination of travel. The estimated risk of developing travel associated typhoid is about:

– 1/3,000 travellers for travel to the South Asia (= high risk) • South Asia is defined as Afghanistan, Bangladesh, Bhutan, India,

Nepal, Maldives, Pakistan, and Sri Lanka. • Among these countries, the large majority (≥ 90%) of cases of typhoid

among travellers were reported from India, Pakistan and Bangladesh

– 1/50,000-100,000 for travel to Sub-Saharan Africa, North Africa and the Middle East, or South America (= intermediate risk)

– < 1/300,000 for travel to the Caribbean and Central America (= low risk).

PROPOSAL FOR A NEW ONE:

•la vaccination contre la fièvre typhoïde est surtout conseillée pour les voyages de plus de trois semaines vers le sous-continent indien

• la vaccination contre la fièvre typhoïde est à considérer pour les voyages aventureux dans de mauvaises conditions sanitaires vers les pays tropicaux ou subtropicaux ou pour les immigrés et leurs enfants qui retournent dans leur pays tropical d’origine pour visiter la famille et les connaissances.

25-11-2015

• vaccination against typhoid fever is particularlyadvisable for trips longer than 3 weeks duration to the Indian subcontinent

•vaccination against typhoid fever can be considered in case of an adventurous trip in poor sanitary conditions to tropical or subtropical countries or for immigrants when they return to their homeland to visit friends and relatives.

• vaccinatie tegen buiktyfus is vooral aangeraden voor reizen langer dan 3 weken naar het Indisch subcontinent

• vaccinatie tegen buiktyfus kan overwogen worden voor avontuurlijke reizen in slechte hygiënische omstandigheden in tropische of subtropische landen of voor migranten en hun kinderen die terugkeren naar hun land van herkomst op bezoek bij familie of vrienden.

Background: • For individuals traveling at short notice to rabies and Japanese encephalitis (JE) endemic countries, concomitant administration of travel

vaccines within a short period is often required.

Methods: • The aim of this study was to determine whether an accelerated (one-week: Days 1 + 8) pre-

exposure rabies (Rabipur, Novartis Vaccines) vaccination regimen administered concomitantlywith a Japanese encephalitis (JE) vaccination (Ixiaro, Valneva) regimen, is non-inferior to the standard (four-week: Days 1, 8, 29) rabies regimen administered alone or concomitantly with the JE vaccine.

• Healthy adults (18 to 65 years) were randomized into Rabies & JE-Standard, Rabies + JE-Accelerated, Rabies-Standard and JE-Standard groups.

• Relative immunogenicity for rabies in each regimen was assessed using the rapid fluorescent focus inhibition test.

• Safety was evaluated up to and including Day 57.

Results: • Non-inferior immunogenicity for rabies was established between the Rabies + JE accelerated

group compared to both the Rabies-Standard and Rabies & JE-Standard groups;• as well as between the Rabies + JE-Standard regimen and the Rabies-Standard regimen. • By Day 57, adequate neutralizing levels were achieved by 97- 100% of subjects across all groups.• Adverse events (AEs) were comparable for all groups.

Conclusions: • An accelerated pre-exposure rabies and JE vaccination regimen is non-inferior to the standard

four-week rabies regimen and may thus provide a more convenient regimen for individuals traveling to endemic countries at short notice.

PO03.10Long Term Immunity 6 Years after Booster Vaccination against Japanese EncephalitisM. Paulke-Korinek1, H. Kollaritsch1, M. Kundi2, I. Zwazl1, C. Seidl-Friedrich1, T. Jelinek3

Background and Objective: Japanese Encephalitis is a mosquito-borne viral infection. In endemic• regions mainly in Southeast Asia, every year about 68,000 clinical cases of Japanese Encephalitis• occur. The only internationally available vaccine to prevent from the viral encephalitis is an inactivated• whole-cell vaccine containing the strain SA14-14-2. Basic immunization is recommended at day 1 and• day 29, followed by a booster vaccination 12 to 24 months later. To date, immunity after the booster• dose in adults has been investigated up to 12 months. This study was initiated to assess antibody• decline and to predict long-term duration of seroprotection.Method: A random sample of 70 volunteers from a preceding booster trial (booster given 15 months• after the primary series, 45% of originally vaccinated) was invited to the follow up study and 67 (96%)• participated approximately 6 years after their booster dose against Japanese Encephalitis. Sera were• analyzed using a 50% plaque reduction neutralization test (PRNT50-test). A positive opinion by• responsible ethics committees was present and all subjects provided informed consent.Result: Six years after the last booster dose, geometric mean titer was still 148 (95% CI:107 to 207),• and 96% of the tested subjects had antibody titers above PRNT50 values of 10, the surrogate level of• protection according to WHO. Antibody titers generally were lower in subjects aged 50 years and• older. Yellow fever vaccination and vaccination against TBE had no significant effects on antibody• titers against Japanese Encephalitis.Conclusion: Long-term protection against Japanese Encephalitis after basic immunization and one• booster dose against Japanese Encephalitis up to 6 years could be shown in the majority of subjects.• This implies that a second booster may not be necessary for at least 6 years after the first booster.Conflict of Interest: The study was supported by Valneva, Austria

Background: • Japanese Encephalitis (JE) virus occurs in wide regions of Asia with over 3 billion people living in areas at risk for JE. • An estimated 68,000 clinical cases of JE occur every year, and vaccination is the most effective prophylactic measure. • One internationally licensed vaccine containing the inactivated JEvirus strain SA14-14-2 is Ixiaro® (Valneva, Austria). • According to recommendations, basic immunizationconsists of vaccinations on day 0, day 28, and a booster dose 12–24 months later. • Protection in terms of neutralizing antibody titers has been assessed up to 12 months after the third dose of the vaccine.• The current investigation was designed to evaluate antibody decline over time and to predict long-termduration of seroprotection after a

booster dose

Method: • In a preceding trial, volunteers received basic immunization (day 0, day 28) and one

booster dose against JE 15 months later. A follow up blood draw 6 years following their booster dose was carried out in 67 subjects. For antibody testing, a 50% plaque reduction neutralization test (PRNT50-test) wasused. PRNT50values of 10 and above are surrogate levels of protection according to WHO standards

Result: • Seventy-six months following the booster dose, 96% of the tested subjects had

PRNT50 titers of 10 or higher. • Geometric mean titer (GMT) was 148 (95% CI confidence interval: 107–207). • Antibody titers were lower in volunteers 50 years of age and older. • Vaccination history against other flaviviruses (yellowf ever or tick borne encephalitis)

did not significantly influence PRNT50titers. • A two-step log-linear decline model predicted protection against JE of approximately

14 years after the booster dose.Conclusion: • Six years after a booster dose against JE, long-term protection could be

demonstrated.• According to our results, further booster doses should be scheduled 10 years

following the first booster dose.

2015

Ixiaro ® is available in Belgium since the summer of 2010

A first booster has been given 12-24 months after the start of the primovaccination.

So in the summer of 2017 the first clients for a second booster may show up.

What will be the advice ? 6 years ? 10 years ? we will wait EMA

EMA 13/08/2015 (website consulted 01/10/2015) “Data on the need for further booster doses are not available”

2015

Ixiaro ® is not available in many countries in Asia, but it might be available under another name : e.g. JEEV (from India), Jespect (from Australia)

Other inactivated Vero cell-derived vaccines are produced in Asia : e.g., Genovax® (Bharat Biotech India), …

27/11/2015

39

Live JE vaccines in Asia • 1 injection for “lifelong” protection (20 y ? 30 y ?)

- BUT longterm immunogenicity data are limited - in children a second injection might be indicated

• Might be useful for expats • Different types / very variable local prices :

– live attenuated (Chengdu – made in China)

– live recombinant - chimeric (Imojev® - made by Novartis-Australia)

Background• More than 300 million travelers visit regions with poor hygiene annually. A significant percentage of

them become colonized by resistant intestinal bacteria such as extended-spectrum beta-lactamase–producing Enterobacteriaceae (ESBL-PE) and may transmit the strains to others and to medical care settings when they return home. .

Methods• Stool samples were collected from 430 Finns before and after traveling outside Scandinavia. • All specimens were analyzed for ESBL- and carbapenemase-producing Enterobacteriaceae (CPE). • Questionnaires were used to survey volunteers about use of antimicrobials as well as other potential

risk factors.

Results • 21 % (90/430) of the travelers became colonized by ESBL-PE -

none by CPE. • Were identified as independent predisposing risk factors

(1) Geographic region (2) occurrence of travelers’ diarrhea (TD) (3) age (4) use of antimicrobial (AB) for TD

Antimicrobials Increase Travelers’ Risk of Colonization by Extended-Spectrum Betalactamase-Producing Enterobacteriaceae

• 11 % of those in subgroup TD−AB−, 21% in TD+AB−, and 37% in TD+AB+ acquired ESBL-PE.

• The risk proved to be highest in South Asia (46%); 23% became colonized in subgroup TD−AB−, 47% in TD+AB−, and 80% in

TD+AB+. • In Southeast Asia, the rates were 14%, 37%, and 69%, respectively.

Conclusions• TD and antimicrobials for TD proved to be independent risk factors,

with up to 80% of TD+AB+ travelers contracting ESBL-PE. • In modern pre-travel counseling for those visiting high-risk regions,

travelers should be advised against taking antibiotics for mild or moderate TD.

Selftreatmemt Travelers’ Diarrhea in Belgian travellers ?

2015

The present Belgian recommendations have been drawn up years ago by infectiologists after intense discussions. The recent publication of Kantele et al. has however forced us to rethink in 2016 the recommendations, and asks for a balanced discussion, taking into account the following:

– What is the impact of a one-day antibiotic treatment, the schedule most often advised for (uncomplicated) diarrhea,

– In which circumstances? To prevent ruining the trip?– Clinical evidence suggests that the Belgian traveler sparsely takes

antibiotic treatment rather than overusing it.– Restricting antibiotic self-treatment may increase (avoidable)

hospitalization in low income country setting (& wrong antibiotic use)– Reviewing the TD treatment policy would preferentially be based on

prospective study data, that are not yet available…..

Belgium does not follow the recommendations to treat TD with antibiotics as liberally as the US does, but the treatment policy is not as restrictive as in Scandinavia and in the Netherlands.

General advice for Mecca pilgrims -required/recommended vaccines• Vaccination with a tetravalent, conjugated ACYW135

meningococcal vaccine is required to obtain a visa.

• Available vaccines in Belgium: Nimenrix® and Menveo®

• The unconjugated 4-valent meningococcal vaccine is not available anymore in pharmacy (July 2013) – it might still be available in the travel clinics and be used in pilgrims

• It remains unclear if children till the age of 2 years are obliged to be vaccinated, but it correct to vaccinate also the little children – on the other hand, see further : children under 12 yrs are discouraged to come to Mecca.

2013 = 2014 = 2015
