Novel RNA vaccine from Arcturus Therapeutics protects mice against SARS-CoV-2

A new study published on the preprint server bioRxiv in September 2020 reports a novel RNA vaccine platform that shows robust protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in mice and performs much better than a conventional mRNA vaccine. This could allow single-dose immunization, allowing progress towards global vaccination.

WHO African Region now certified as wild polio-free after four years

Today, the Africa Regional Certification Commission certified the WHO African Region as wild polio-free after four years without a case. With this historic milestone, five of the six WHO regions – representing over 90% of the world's population – are now free of the wild poliovirus, moving the world closer to achieving global polio eradication.

Single-dose adenovirus-vectored vaccine protects mice against SARS-CoV-2

The researchers selected the human adenovirus type 5 on which to base their vaccine because this replication-defective vector had already been used in their Ebola vaccine, with an excellent safety and immunogenicity profile in a phase 1 trial. The current study aimed to produce a vaccine that could offer mucosal vaccination and enhanced protection against this respiratory virus.
