Can we create a universal Covid vaccine?

Can scientists develop a vaccine which can combat the coronavirus and all its variants? There have been three lethal outbreaks caused by coronaviruses this century: SARS in 2002, MERS in 2012 and now SarsCov2. Scientists predict we will eventually encounter SarsCov3. That’s why the race is on to develop a universal vaccine to combat the coronaviruses and variants we know about, and the ones we have yet to confront. But attempts to create a universal vaccine for viruses such as influenza and HIV have been going on for decades - without success. Before 2020, proposals to create a vaccine against coronaviruses were not thought important enough to pursue since many just cause the common cold. Now that we understand their real threat, can scientists succeed in creating a vaccine to fight this large family of viruses,?Produced and presented by Sandra Kanthal Editor: Emma Close Production Coordinators: Maria Ogundele and Jacqui Johnson Sound: James Beard and Rod Farquhar
