Brief Summary

This study aims to investigate the effects of aP booster vaccination in children, young adults and elderly on the (long-term) immune response to B. pertussis in three European countries with a different epidemiological background and primary vaccination schedule for pertussis.

Outcome Measures

Primary Outcomes (1)

  • Change from baseline of pertussis toxin-specific IgG antibody levels to 28 days after vaccination

    28 days

Secondary Outcomes (7)

  • Amount of pertussis toxin (PT) specific IgG antibody one year after vaccination with Boostrix-IPV

    1 year

  • Change from baseline in pertussis toxin (PT) specific IgG-subclasses and avidity levels to 28 days and 1 year after vaccination with Boostrix-IPV

    28 days and 1 year

  • Change from baseline of antigen-specific IgG antibody levels against other pertussis vaccine antigens (such as FHA) and non-pertussis vaccine antigens (such as diptheria and tetanus toxoid) to 28 days and 1 year after vaccination with Boostrix-IPV

    28 days and 1 year

  • Change from baseline of functional pertussis-specific antibody levels to 28 days and 1 year after vaccination with Boostrix-IPV

    28 days and 1 year

  • Change from baseline of B cell responses against Bordetella pertussis vaccine proteins after vaccination with Boostrix-IPV

    7 days, 28 days and 1 year

  • +2 more secondary outcomes

Study Arms (4)

Children aged between 7-10 years of age

ACTIVE COMPARATOR

Healthy children from 7 up to 10 years of age, determined by date of birth (dd/mm/yyyy), at the time of the first visit. Male + female, approximately equally distributed, n = 36 in each country. They will receive Boostrix®-IPV combination vaccine.

Biological: Boostrix®-IPV combination vaccine

Children aged between 11-15 years of age

ACTIVE COMPARATOR

Healthy children from 11 up to 15 years of age, determined by date of birth (dd/mm/yyyy), at the time of the first visit. Male + female, approximately equally distributed, n = 36 in each country aiming for comparable numbers of participants with aP vs wP vaccination background. They will receive Boostrix®-IPV combination vaccine.

Biological: Boostrix®-IPV combination vaccine

Adults aged between 20-34 years of age

ACTIVE COMPARATOR

Healthy young adults from 20 up to 34 years of age, determined by date of birth (dd/mm/yyyy), at the time of the first visit. Male + female, approximately equally distributed, n = 25 in each country. They will receive Boostrix®-IPV combination vaccine.

Biological: Boostrix®-IPV combination vaccine

Adults aged between 60-70 years of age

ACTIVE COMPARATOR

Older adults from 60 up to 70 years of age determined by date of birth (dd/mm/yyyy), at the time of the first visit. Male + female, approximately equally distributed, n = 25 in each country. They will receive Boostrix®-IPV combination vaccine.

Biological: Boostrix®-IPV combination vaccine

Interventions

A licensed aP (acellular) booster vaccine developed by GlaxoSmithKline.

Eligibility Criteria

Age7 Years - 70 Years
Sexall
Healthy VolunteersYes
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Normal general health
  • Within the right age group for the cohort
  • Received all regular vaccines for their age group according to the Dutch NIP, UK NIP or Finnish NIP; a copy of the vaccination booklet will be included in the participant's documents. If booklet is not available for cohorts A, B and C, vaccination status will be checked although, for cohort C and D this booklet might not be available due to their age;
  • Provision of written informed consent
  • Willing to adhere to the protocol and be available during the study period.

You may not qualify if:

  • Chronic infection
  • Known or suspected immune deficiency;
  • History of any neurologic disorder, including epilepsy;
  • Previous administration of serum products (including immunoglobulins) within 6 months before vaccination and blood sampling;
  • Known and/or suspected allergy to any of the vaccine components (by medical history);
  • Occurrence of a serious adverse events (SAEs) after primary DTwP-IPV vaccination, DTaP-IPV vaccination or any other vaccination (by medical history);
  • Children between 8 and 10 years of age eligible for cohort A in the Netherlands who have already received the diphtheria and tetanus toxoid vaccine (DT)-IPV booster vaccination according to Dutch NIP around 9 years of age;
  • Mixed wP and aP priming within a participant, cohort B;
  • If a participant has a severe acute (infectious) illness or fever (\>38°C) within 14 days prior to T0, participation will be postponed or cancelled. In case the participant has fever within 2 days before sampling at T4 or T5, the appointment will be postponed for 4 days, if possible.
  • Antibiotic use within 14 days of enrolment.
  • Any vaccination within a month before enrolment.
