From the beginning, emphasis was Latest Mailing Database placed on the development of vaccines, not only for domestic consumption, but also for export to countries in the global South. It is this research and production structure that has allowed Cuba to create two ready-to-use vaccines in a very short time. Both "Abdala" and "Soberana-2" are based on a Latest Mailing Database protein platform, a method used for decades against polio, tetanus and other diseases. Unlike the novel messenger RNA vaccines from BioNTech and Moderna, this is an "old school" technology.More than seven million doses have already been applied in a campaign that has been concentrated in the country's Latest Mailing Database capital, originally the epicenter of the infectious process. In all other provinces, the incidences are increasing strongly.
But the advantage is that these vaccines Latest Mailing Database can be produced in existing factories, experience indicates a low level of serious side effects, and extreme cooling is not needed. And they are effective vaccines. The results of the phase 3 studies Latest Mailing Database have already been published, showing an effectiveness of 92% for Abdala against symptomatic disease after completing the three-dose schedule, and for Soberana-2, an effectiveness of 91%. Critics Latest Mailing Database have disputed these numbers, pointing to a lack of transparency and insufficient documentation in scientific journals.
It is possible that with the Latest Mailing Database practical application it is necessary to make adjustments. Although both phase 3 studies were done on more than 40,000 people, the absolute numbers on which efficacy estimates are based are not Latest Mailing Database high; for Soberana-2 there were five cases of symptomatic disease in the vaccinated group versus 51 in the placebo group. But beyond the studies, to see that the vaccines are effective, the ongoing vaccination campaign speaks for itself. When the country's medical staff were vaccinated in early March, the number Latest Mailing Database of infections among health sector employees immediately fell. This has also been observed since the beginning of the mass vaccinations in Havana, in the month of May.
