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.

Although Cuba is "sovereign" in the development of its own vaccines, as the name of one of them suggests, this is not the case in terms of equipment and components, which must be imported. Added to the aforementioned problems, as always occurs in Cuba, is the burden of the US embargo, which limits the opportunities to acquire machinery and supplies. In addition, Washington's threats to international banks make financial transactions with the island complex and costly maneuvers. As a result, Cuba will initially have to focus on producing enough vaccine for its own population. Export options are also expected to be negotiated, preferably with pre-financing. Another option is to sell licenses to countries like Argentina or Vietnam, which have their own production capacities. In the past, the WHO has already purchased Cuban vaccines for vaccination campaigns in countries of the global South and could do so again in the current Whatsapp Mobile Number List medium term, protein-based vaccines, such as the Cuban ones, are also suitable as booster shots. By the way, as a gesture of solidarity, there was a first delivery of 30,000 doses from Abdala to his ally Venezuela, whose oil deliveries to Cuba have decreased, but are still essential to supply the island. Another 12 million doses have been promised, but without specifying the delivery date. As important as these prospects are, Cuban vaccines can overcome the country's health crisis, but not the economic one. This remains the task of a reform agenda that should aim to revive the entire economy and not rely on the biotech sector to become the goose that lays the golden eggs. And even when they are an achievement of the health system, vaccines cannot be the ones that respond to the long-accumulated crisis of political confidence that is becoming evident in the streets these days.
