The chief scientist of the WHO, Soumya Swaminathan, acknowledged this Friday that the new efficacy data for the coronavirus vaccine developed by the German firm CureVac (47%) are “disappointing”, Although he pointed out that it is common for not all investigations to be successful and encouraged further investigation.
“The results are below the 50 percent limit we had set, so it is disappointing”Admitted the Indian expert at a press conference, noting that it was especially striking given that previous vaccines with the new messenger RNA technology, such as those from Pfizer or Moderna, had been successful.

“This warns us of something important, that in the development of vaccines not all will have the same results, and we cannot assume that all messenger RNA vaccines will respond in the same way”, Assured the representative of the World Health Organization.
Swaminathan indicated that the CureVac It initially offered certain advantages, such as the fact that it could be stored without the need for ultra-cold temperatures.
The poor results in vaccine tests, he said, “They are something normal”. “Actually, we have been very fortunate to have so many successful vaccines.”, He said in reference to the approximately a dozen pharmaceutical companies that are already distributing their doses globally.
“We must continue to support research into vaccine candidates, particularly those that are easier to use.”, He concluded, calling for prioritizing those that are easy to store, those that can be administered in a single dose or those that do not need to be injected (for example, those that allow the oral route).
The second preliminary analysis of the vaccine CureVac was only 47% effective in preventing COVID-19, something that caused the German biopharmaceutical to crash on the stock market.
