More than seven million doses have already been applied in a campaign that has been concentrated in the country's capital, originally the epicenter of the Whatsapp Mobile Number List infectious process. In all other provinces, the incidences are increasing strongly. In the capital, however, where half the population has already been vaccinated, infections have fallen to half their peak value. As in other countries with high levels of vaccination, a rebound is seen with the recent entry into Cuba of the aggressive Delta variant. Phase 3 studies of Cuban vaccines were still carried out with the prevalence of the Beta strain.
Even if they seem to give good immunity against Delta as well, it cannot be excluded that – as has been seen with other vaccines – the effectiveness is Whatsapp Mobile Number List somewhat lower against this variant, especially in the case of incomplete vaccination. A Whatsapp Mobile Number List was also carried out in Iran for the Sovereign-2 vaccine, with 24,000 participants, and there the Cuban vaccine has already obtained emergency approval. In Cuba, approval was recently given for Abdala while that for Soberana-2 is expected in the coming weeks.
Presumably, the Cuban approval authority waits with formal approval until all the data is required by the World Health Organization (WHO) protocols are available. Because, in addition to overcoming the pandemic in its own territory, Cuba also hopes to export its vaccines. But production at scale faces big obstacles. The 100 million doses once Whatsapp Mobile Number List announced for production this year will remain a theoretical possibility. The supplies needed have become extremely scarce as companies around the world bet on developing protein-based vaccines, be it Novavax in the United States, Sanofi/GlaxoSmithKline in Europe, or Anhui in China.
