Completed & Ongoing Research

Influenza Vaccine Study

Influenza (flu) is a highly contagious respiratory infection caused by an influenza virus. Children are especially vulnerable and at greater risk of flu complications. Researchers would like to compare 2 licensed flu vaccines to find out which one provides better protection for young children.The study involves 7 visits over 18 months at the VEC located at the BC Children’s Hospital Research Institute in Vancouver. Visits will include blood tests, 3 flu shots (over 2 seasons), and questions about your child’s health.



Annual Influenza Vaccine Safety Survey of Adverse Events Following Immunization

flusurveyThis is the 8th year of the Vaccine Safety Survey. For this year’s survey (2019).
This study is a rapid online assessment of the annual Influenza (flu) vaccination programs at seven sites across Canada. It is being conducted by Canadian National Vaccine Safety (CANVAS) network and includes more than than 20,000 people who receive their flu vaccine. The purpose of this study is to monitor adverse events (side-effects) after the flu shot using an online survey. We are interested in learning about any new health problems that develop after receiving the flu shot which result in a visit to a health care provider.


 Parents’ Changing Feelings About Vaccines

You may have become less worried or more worried about vaccines over time, and your concerns may have been about specific shots or about vaccines in general. Your child may have received all, some, or none of the recommended shots

Men B Study

menbMeningococcal B disease can make people sick very quickly and is good at spreading from person to person. Doctors are trying to find out the fastest way to give the vaccine in case there are a lot of people getting sick all at once.
This research looked at two groups of 17 to 25 year olds. This age group tends to be at higher risk of meningococcal disease because of close person-to-person contact in social settings and where they live (university campus, dorms etc). The study used the Meningococcal B vaccine Bexsero, which is currently licensed and available in Canada
This study was conducted by Dr. Soren Gantt at the VEC at BC Children’s Hospital in Vancouver.


Hepatitis B Shots – Is another one needed in school? (2014)

BC Gov poster picture 1
This study looked at whether the Hepatitis B vaccine that children had as babies still protects them many years later. Children 10-11 years old and adolescents 15-16 years old were invited to participate. Participants and their parents will find out if the Hepatitis B vaccine is still giving protection or, if not, whether a Hepatitis B ‘booster’ dose will help protect against the disease.


Understanding factors influencing parental decisions regarding Rotavirus vaccination in BC (2014)

IMG_0181Rotavirus is the most common cause of diarrhea in children under 5 years of age. The Rotavirus vaccine is given by mouth, usually at 2 and 4 months of age. This study is a telephone survey looking to understand factors influencing parental decisions about Rotavirus vaccination and to develop strategies to improve Rotavirus vaccination coverage across BC. This study is being conducted by Dr. Monika Naus at BC Centre for Disease Control. .

9 Valent HPV Vaccine 2014 – ongoing (recruitment closed)

hpvCurrently there are two licensed HPV vaccines available in Canada. Gardasil™ a HPV vaccine that protects against four types of HPV (6, 11, 16 & 18) and Cervarix™, that protects against two types of HPV (16 & 18).  This research will study a new investigational HPV vaccine that may provide protection against nine HPV types (6, 11, 16, 18, 31,33,45,52 and 58). The study will look at 2 doses of HPV Vaccine in 9-14 year-olds compared to young women.
HPV is a common virus that can affect both males and females who are sexually active. Many people who have HPV do not show any signs or symptoms, so they can pass on the virus without even knowing it.  When the virus does not go away it can cause genital warts, precancerous lesions or genital, cervical and oral cancer depending on the type of HPV.

Canadian Meningococcal C Programmes (2009)

Universal programs to vaccinate children have been in place in Canada since 2002. Provinces introduced the MenC vaccine at various times and with varying dosing schedules. It is not clear which province has the best, most protective schedule. We know that nearly all children are protected right after the 12 month shot but protection weakens over time and might be lost in some children. The goal of this study is to see which of three provincial MenC vaccination schedules gives the longest lasting protection to children and if a booster shot is needed.
Meningococcal C infection is caused by a germ (or bacteria) that spreads from one person to another during close face-to-face contact. MenC infections are rare but are an important cause of serious illness, death and long term disability especially in younger children. MenC vaccines protect by getting the body to make antibodies (blood proteins) that can kill the meningococcal germ.

Controlled Comparison of Seasonal Influenza Vaccines for Canadian Seniors 2011-2012

In September 2011 over 900 adults aged 65 and older were enrolled in a Canada wide study to evaluate 2 new influenza vaccines compared to the standard seasonal influenza vaccine.  Adults were randomized to receive either the usual seasonal influenza vaccine (Trivalent Influenza Vaccine; TIV), a new Adjuvanted Influenza Vaccine (AIV), or a new Intradermal Influenza Vaccine (IDV).  Blood samples were collected before and after vaccination to measure the immune response to each of the 3 vaccines to determine if better protection was provided by the newer vaccines.
