No evidence has shown that typhoid vaccine is useful in controlling common-source outbreaks. (cdc.gov)

If IG administration becomes necessary after a live vaccine has been given, interference may occur, and thus the vaccine may have to be repeated after at least a 3 month wait. (cdc.gov)
Secondary transmission of vaccine organisms does not occur because viable organisms are not shed in the stool of vaccinees. (cdc.gov)
Life-threatening intestinal hemorrhage and intestinal perforation may occur in 3% of hospitalized patients with typhoid fever. (kidsnewtocanada.ca)

A single dose of injectable vaccine protects for three years, but will not protect against para-typhoid fever. (centraltravelclinic.co.uk)

It was this lab that created the Oxford-AstraZeneca vaccine, which saved around 63 lakh lives. (theweek.in)
The development of the Oxford-AstraZeneca vaccine has had an immeasurable impact on the lives of children and young people across the world. (ox.ac.uk)

If IG needs to be administered because of imminent exposure to disease, live virus vaccines may be administered simultaneously with IG recognizing that vaccine-induced immunity may be compromised. (cdc.gov)
Booster vaccines may enhance waning immunity and expand the breadth of immunity against SARS-CoV-2 variants of concern. (umaryland.edu)

The findings from this study newly published online in npj Vaccines support the use of TCV booster doses to confer long-term protection against typhoid fever in young children. (ivi.int)
Kirsten E. Lyke, MD , Professor of Medicine at UMSOM, is Co-Chair and site Principal Investigator for the study and presented data to the U.S. Food and Drug Administration's (FDA) expert vaccine panel in October that led to the recommendation for mix-and-match booster doses following completion of Emergency Use Authorization (EUA) regimens. (umaryland.edu)
A planned sample of up to 76 participants - aged 18 to 55 and in good health - will be randomised to either receive two doses of the new paratyphoid vaccine or a placebo given 14 days apart. (ox.ac.uk)

The major benefit of the cholera vaccine is for entry into a few countries requiring a certificate. (cdc.gov)

Now (1976) we are being worked on again by the vaccine -epidemic makers in their effort to force another multi million dollar vaccine sale caper. (educate-yourself.org)

Various vaccines that protect against typhoid are available: Typherix, Typhim Vi and and an oral preparation (3 capsules) called Vivotif. (centraltravelclinic.co.uk)

This research underpins half of the vaccines in the NHS childhood immunisation schedule and is cited in the vaccine policies of many countries around the world. (ox.ac.uk)
His wider work has also had a profound impact on childhood immunisation in the UK, supporting the introduction of half of the vaccines currently given to children. (ox.ac.uk)
