Clinical trials: Immunity to Ticks
Tick-Borne Encephalitis
Cervicovaginal Immune Responses to 3 Deltoid or Thigh Intramuscular (IM) TicoVac
Many viral infections of global importance, including HIV, are transmitted across the mucosal surface of the genital tract. As immunity against these infections is likely to be primarily mediated by antibodies in mucosal…

Immune Modulation, Tuberculosis
CD8 Reactivity to Microorganisms in Blood and Breast Milk
Background: When a person is exposed to something that causes an infection, the body sends a type of cell called CD8 T cells to attack it. Those cells are also found in breast milk.

Encephalitis, Tick-Borne
Study of the Safety, Tolerability and Immune Response of TBE Vaccines Administered to Healthy Children
The purpose of this study is to evaluate the safety, immunogenicity and tolerability of TBE vaccines administered to children.
- Trial name
- NCT00311441
- Testing
- Tick-Borne Encephalitis vaccine
- Where
- Germany
- Volunteers
- 300 people, healthy volunteers welcome

Tick-borne Diseases, Tick Resistance
Human Immune Response to Ixodes Scapularis Tick Bites
Background: Each year, the number of cases of tick-borne diseases increases. The deer tick (Ixodes scapularis) is the vector of at least 7 pathogens that cause human diseases, including Lyme disease.
- Conditions
- Tick-borne Diseases, Tick Resistance, Lyme Disease
- Trial name
- NCT05036707
- Testing
- Xenodiagnosis Ticks, skin biopsy, blood draw
- Where

Tick-borne Encephalitis
New Study - Humoral Response to Tick-borne Encephalitis Vaccine in Elderly
The risk for tick borne encephalitis increases in Sweden. Together with an increased awareness of the possibility to acquire protection by vaccination, this has led to an increase in the number of doses of the vaccine distributed…

Tick Bites, Immunity to Ticks
The Uninfected Ixodes Scapularis Human Tick Challenge Model
An innovative way to prevent multiple tick-borne diseases is an anti-tick vaccine, i.e. targeting the vector to prevent transmission of pathogens from the tick to the host.

- TICKME (NCT05965635)
- Testing
- Ixodus scapularis nymphs
- Where
- Netherlands

Tick-borne Encephalitis
Humoral Response to Tick-borne Encephalitis Vaccine in Elderly
Antibody titers after tick-borne encephalitis (TBE) vaccination are less in elderly and vaccination breakthroughs are more common in this age group.
