Cuba’s recent push to vaccinate children against COVID-19 has emphasized the work of Cuban scientists in developing vaccines for children, such as Vicente Verez, director-general of the Finlay Vaccinations Institute, who was part of the group that produced the Soberana line of COVID-19 vaccines for children and adults. 

Maria Elena Bottazzi, co-director of Texas Children’s Hospital’s Center for Vaccine Development, said Cubans were unaware of the multibillion-dollar grants given to foreign corporations to develop vaccines to combat the SARS-CoV-2 coronavirus.

The difficulties for Cuba were enormous during the vaccine creation and manufacturing process, as the US government’s intrusive actions became one of the issues that Cuba had to pass for their vaccinations to be successful.

Much of the cutting-edge pharmaceutical supplies and equipment arrived from the United States and European countries, and Cuba attempted to get around the blockade by purchasing via third-party countries.

Years of effort on children’s vaccines paid off for Cuban scientists since the Moderna & Pfizer-BioNTech medicines used cutting-edge technology whereas the Cuban vaccines used a more conventional process.

The COVID-19 vaccines for minors (Soberana Plus, Abdala, and Soberana Plus) are conjugated subunit formulations that comprise harmless pieces of a virus to trigger the immune system to manufacture antibodies.

Cuba initiated the world’s first mass childhood immunization campaign against COVID-19 in September last year, targeting 1.7 million children aged 2 to 18 with a three-dose regimen.

With the number of cases falling in recent weeks and no deaths from the disease reported for nearly three weeks, Cuban officials have decided to stop the required wearing of face masks, a decision that was made possible by the efficacy of vaccination.
