Rift Valley fever vaccine ‘safe for pregnant animals’
Rift Valley fever is a virus that infects sheep, goats, cattle and camels.

Research will aid the development of ChAdOx1 RVF for human use

The Rift Valley fever (RVF) vaccine is safe for pregnant animals, according to a collaborative study led by The Pirbright Institute. 


The research, published in the journal npj Vaccines, found that pregnant sheep and goats vaccinated with a single dose of ChAdOx1 RVF remained healthy and suffered no pregnancy loss after being exposed to a virulent strain of RVF virus.

The team will use their discovery to progress the development of the vaccine, which could be the first to be used against both a human and animal disease.


“Our study has provided further evidence of the vaccine’s effectiveness and safety,” said Dr Anna Stedman, lead author of the study. “Ensuring ChAdOx1 RVF can be used in pregnant animals will help livestock owners to protect their animals in the event of an outbreak, which in turn will reduce their own risk of infection.”


Rift Valley fever is a virus that infects sheep, goats, cattle and camels. Prevalent across Africa and the Arabian Peninsula, the infection results in high mortality and poor outcomes during pregnancy. 


RVF also poses a threat to human health, but no licenced human vaccine is currently available. People can contract the disease through contaminated tissues and fluids of livestock, as well as being bitten by infected mosquitoes.


ChAdOx1 RVF was previously shown to be safe and effective at protecting animals and has since been scheduled for human trials. Until now, however, its safety in pregnant animals has not been verified. 


“This research will aid the development of ChAdOx1 RVF for human use, and for the first time we may see a vaccine that can be deployed against the same virus in both animals and humans,” said Professor Bryan Charleston, Director of The Pirbright Institute.

Professor George Warimwe, leader of the Rift Valley Fever Vaccine Programme at the University of Oxford added: “This has been a tremendous collaborative achievement. The excellent safety profile of the vaccine in pregnant livestock will support further development of the product for use in both livestock and humans.”

Vets to run marathon for World Animal Protection

News Story 1
 Two recently graduated veterinary surgeons will be running the London Marathon in April to raise money for the charity World Animal Protection.

Alex Bartlett and Maeve O'Neill plan to run the race together if they are given the same start times.

Dr O'Neill said: "You're always limited in what you can do to help animals, so it is nice to raise money for a charity that helps animals around the world."

Dr Bartlett added: "I have never run a marathon before and am excited to run my first one for such a good cause!"

Both Dr Bartlett and Dr O'Neill have fundraising pages online.

BSAVA releases new Guide to Procedures

The British Small Animal Veterinary Association (BSAVA) has published a new edition of its Guide to Procedures for Small Animal Practice.

It has added four new procedures; cystostomy tube placement, endotracheal intubation, point-of-care ultrasound and wet-to-dry dressings.

BSAVA says that it is an essential step-by-step guide to diagnostic and therapeutic procedures performed in practice. The textbook includes new images and illustrations, as well as high-definition videos for use prior to procedures.

Nick Bexfield and Julia Riggs, editors of the new edition, said: "We have built upon the success of the previous editions by responding to the feedback received from the BSAVA readership, and hope this new guide helps to further increase the confidence and accuracy with which these procedures are performed."

Print copies are available in the BSAVA store, with a digital version in the BSAVA library.
