Cuba has announced positive and promising results for a number of
separate COVID-19 vaccines it is currently developing, but
U.S. sanctions against the small island nation are hampering the
development and rollout of the potentially life-saving treatments.
Two candidates, named Sovereign 1 and Sovereign 2, have generated
antibodies blocking infection in animals and are showing similarly
encouraging signs on tests on human subjects. Meanwhile, a separate
vaccine, based on a protein from the hepatitis B virus, is unique in
that it is delivered through the nasal tract and does not require a
needle to administer.
Should any of these efforts ultimately succeed, the Caribbean nation -
already a medical powerhouse that has developed a lung cancer vaccine
and methods to stop mother-to-baby HIV and syphilis transmission -
will likely become an important supplier to other Latin American and
developing countries who have been effectively shut out from
purchasing COVID vaccines from Western companies, as rich nations have
already begun hoarding coronavirus medicines.
However, Cuban immunization developments are being seriously hamstrung
by the actions of the U.S. government, primarily due to the
decades-long blockade on the island, something which the Cuban
government estimates has cost it over 750 billion U.S. dollars.
