A new vaccine for Covid-19 has been developed by Cuban researchers at the Finlay Institute of Vaccines in Havana. The vaccine has just started its second phase of clinical trials. Soberana (Spanish for "sovereign") 2 is a conjugate vaccine - meaning an antigen is fused to a carrier molecule to bolster the vaccine's stability and effectiveness. The communist-run government hope to vaccinate everyone in Cuba this year and there are plans to export it to other countries in Latin America.
