UK, US teams begin trials of COVID-19 nasal spray vaccines

Scientists at Oxford University in the UK will test whether the AstraZeneca coronavirus vaccine can be administered through a nasal spray, after a US company launched a trial of its own spray in the UK.It is hoped that sprays, which are already used to give children flu vaccines, may prove superior to injections in targeting immune cells more susceptible to respiratory viruses in the future, concentrating on the lungs, throat and nose.They may also alleviate issues for people with a fear of needles, and ease supply problems owing to the complexity of manufacturing, transporting and storing jabs.The Oxford team is planning for 30 volunteers to receive the spray and then be tracked for four months in the initial stage of the trial, before expanding the scale if found to be safe.Comments Read Next2 hours agoPhilippines marks daily record for Covid-19 cases2 hours agoSaudi: New COVID-19 cases surpass 5002 hours agoHalf billion COVID-19 vaccine jabs given3 hours agoUAE administers 69,142 vaccine doses in 24 hours7 hours agoUAE reports 2,128 new coronavirus cases, 6 deaths7 hours agoGlobal coronavirus cases cross 125 million11 hours agoBahrain: 841 new cases, 718 recoveries recorded1 day agoGlobal coronavirus cases top 124.6 million1 day agoSaudi: Restaurant, salon
