RNA vaccines produced by Pfizer/BioNTech and Moderna were amongst the first vaccines approved for emergency use in fighting the COVID-19 pandemic. The latest edition of Periodic Graphics in Chemical & Engineering News looks at how these vaccines are made. Click through to the C&EN site to view the full graphic.
Relatively hot on the heels of the Pfizer & BioNTech RNA vaccine, today the UK has approved the Oxford University & AstraZeneca COVID-19 vaccine. The Oxford vaccine is a viral vector vaccine, which works slightly differently to the RNA vaccines. This graphic, made with the Royal Society of Chemistry, looks at how they work and highlights other vaccines of this type in use or development for COVID-19.
