Coronavirus Vaccine Nears Final Tests in Cuba. Tourists May Be Inoculated.

HAVANA — People wait in line for 4 hours to purchase detergent in Havana. Cuban pharmacies are out of ache treatment. There are nationwide bread shortages.

And but the Cuban authorities says it’s getting ready to a rare scientific achievement: the mass manufacturing of a coronavirus vaccine invented on the island.

One of the 4 vaccines developed by Cuban scientists will enter a ultimate section of testing subsequent month, an important step towards regulatory approval that, if profitable, may put the island on the trail to inoculate its total inhabitants and start exports overseas by 12 months’s finish.

If the vaccine proves protected and efficient, it might hand the Cuban authorities a big political victory — and a shot at rescuing the nation from financial damage. For a rustic that has for many years touted its refined well being care system as proof of the advantages of socialism, the vaccine additionally affords a singular public relations alternative.

The vaccine heading for a ultimate section of trials known as Sovereign 2, in a nod to the satisfaction the island takes in its autonomy, regardless of many years of hostility from its neighbor to the north. Already, Cuba is floating the thought of engaging vacationers to its shores with the irresistible cocktail of solar, sand and a shot of Sovereign 2.

Vicente Vérez, one of many scientists main the workforce that developed the vaccine, has mentioned that the island may supply vaccinations to all foreigners who journey there.

“It’s not just medicine and humanitarianism; there’s a big economic payoff if they can get the virus under control,” mentioned Richard Feinberg, a Cuba knowledgeable on the University of California San Diego. “It will be not only immediate income, but a boost to the reputation of the Cuban pharmaceutical biotech sector, which will enable them to market other medical products.”

Cuban scientists say the federal government will in all probability give away some doses to poor international locations, in retaining with its longstanding follow of strengthening worldwide relations by donating drugs and sending docs to handle public well being crises overseas.

“Cuba always donated vaccines,” mentioned Gerardo Guillén, a scientist growing two of the 4 vaccines on the state-owned Center for Genetic Engineering and Biotechnology. “We help other countries.”

Cuba started to pour cash into biotech in the Eighties, as a part of Fidel Castro’s drive to make the nation self-sufficient in the face of a U.S. embargo that made it troublesome to acquire medication produced overseas.


The funding in public well being gave rise to dozens of medical analysis establishments and a surplus of docs, which Cuba sends to different international locations in medical missions.

In 2019, the leasing of docs, nurses and technicians introduced in $5.4 billion, twice as a lot as tourism, a serious driver of the economic system.

The island’s biotech sector can be nicely developed. Cuba makes eight of the 12 vaccines administered to youngsters on the island and exports vaccines to greater than 30 international locations.

“It is a biotech juggernaut,” mentioned Gail Reed, the editor of MEDICC Review, a peer-reviewed journal of Cuban and growing world drugs, in regards to the island. “The accomplishments are undeniable.”

Cuban scientists have additionally developed progressive remedies, including a lung cancer vaccine, which is in trials with the New York-based Roswell Park Comprehensive Cancer Center.

“Sometimes people think because it’s Cuba, they’re just making these drugs in their garage and giving them to people, and that’s not true,” mentioned Candace Johnson, Roswell Park’s president. “They’re very much practicing with exactly the same high standards that every other country does producing these drugs.”

Ms. Johnson mentioned that Cuban scientists demonstrated that they “adhered to all the appropriate standards and controls” earlier than she was capable of carry the lung most cancers drug to New York.


Producing the coronavirus vaccine was made extra sophisticated by the Trump administration’s tightening of sanctions on Cuba. Scientists say they haven’t been capable of purchase all of the tools and uncooked supplies they want, together with spectrometers used for high quality management. The two analysis teams engaged on the drug have just one that’s highly effective sufficient to investigate the vaccine, Dr. Guillén mentioned, and it’s about 20 years outdated.

“Cubans not only are able to make old cars still work, they can manage to make old equipment work,” mentioned Mitchell Valdes Sosa, the director of the Cuban Neurosciences Center.

The Sovereign 2 vaccine has progressed by way of two phases of trials and is ready to enter a 3rd section, the place it will likely be examined on round 150,000 individuals in Cuba and in Iran, which has proven curiosity in buying the drug. Mexico can be in talks with the Cubans to take part in the third section of trials.

Like the vaccine being developed by Novavax, a U.S. firm, Sovereign 2 is a protein-based vaccine that incorporates a part of the coronavirus. It requires three doses administered in two-week intervals and, in contrast to the Moderna and Pfizer vaccines, doesn’t must be saved in deep freeze — which can be a draw for poorer international locations that usually lack the tools to maintain so many doses frozen.

Dr. Vérez mentioned in a textual content message that Sovereign 2 is “very safe with very few adverse effects,” a requirement to maneuver onto a 3rd and ultimate section of trials. Scientists is not going to publish its efficacy price till the trials are accomplished. It continues to be unclear whether or not the vaccine will defend in opposition to new variants, considered one of which has already been detected on the island.

The authorities is optimistic and boasts that it may produce 100 million doses this 12 months, greater than sufficient to vaccinate all the nation of 11 million and, probably, international guests.

But Cuba could not have the tools essential to manufacture its vaccine at that scale. U.S. sanctions have raised the price of buying uncooked supplies and have sophisticated transfers of funds into the island.

“It might get difficult to purchase enough vials for their 100 million doses,” mentioned José Luis DiFabio, the previous World Health Organization consultant in Cuba. “Or if you have equipment that needs to be repaired, you don’t have access to the parts that you might need. Or instead of getting something in a week, you get it in a month.”

And opening the doorways to vaccine-hungry vacationers could create new issues.

Cuba restricted the unfold of the virus early on, leaning on its tight management of the inhabitants and an environment friendly system for delivering well being care. Anyone identified with the virus was instantly hospitalized and placed on a cocktail of Cuban and generic medication.


The authorities remoted their shut contacts and monitored them for signs. Cuba reported simply 12,225 confirmed coronavirus circumstances and 146 deaths in 2020, among the many lowest charges in the Western Hemisphere.

Then, following the choice to open worldwide air journey in November after a seven-month closure, case numbers spiked. Authorities are actually battling the worst outbreak because the pandemic started, with extra circumstances registered in January than in all of final 12 months, and just lately set a 9 p.m. curfew in Havana.

The authorities hasn’t but introduced any particular plans for inoculating vacationers, however must take into accounts the size of time it might take to ship all three pictures required by Sovereign 2.

Dr. Guillén mentioned that quite than keep on the island for a month and a half, vacationers could also be given the choice to get one shot on the island, and pack the opposite two doses in their suitcase for vaccination again house.

The plan to open vaccination to vacationers seems, to some, to be a dangerous and shrewdly capitalist gambit to draw guests, and with them the exhausting foreign money the island desperately wants. The mixture of the pandemic and sanctions have created the worst financial disaster the nation has skilled because the fall of the Soviet Union in the Nineteen Nineties, consultants say.

Cuban scientists, nonetheless, insist the purpose is to unfold well being. Any revenue, they are saying, is merely a aspect impact.

“We are not a multinational where return on investment is our No. 1 priority,” Mr. Vérez, who’s main growth of the vaccine, mentioned in a latest information convention. “Our first priority is to create health, and return on investment is a consequence of that.”
