On Monday, July 12, in an online conference, the World Health Organization’s chief scientist, Soumya Swaminathan, warned about the danger of mixing and matching vaccines from different laboratories that some countries have started to do.
“There are people who are thinking about mixing and matching. We receive a lot of queries from people who say they have taken one [dose] and are planning to take another one (doses),” Dr. Swaminathan said. “So, it’s a little bit of a dangerous trend here. We’re in a data-free, evidence-free zone here as far as mix-and-match. There is limited data on mix and match.”
“There are studies going on, we need to wait for that. Maybe it will be a very good approach. But, at the moment we only have data on the Oxford-AstraZeneca vaccine, followed by Pfizer. It will be a chaotic situation in countries if citizens start deciding when and who will be taking a second, a third and a fourth dose,” she added.
Dr. Soumya Swaminathan is the same Dr. who, in December 2020, stated that vaccines are not effective in preventing contagion and that vaccinated people could still infect others.
According to the Daily Mail, Thailand announced last week that it would begin administering one dose of the AstraZeneca vaccine and one dose of the Chinese Sinovac vaccine to combat the Delta strain.
Last month, Canada also indicated that people who received one dose of AstraZeneca would be able to receive the second dose from Pfizer or Moderna.
In Argentina’s capital city of Buenos Aires, health minister Fernando Quiros called for ‘volunteers’ who had received a dose of one vaccine to combine a second dose from another laboratory. However, there is no data to guarantee the safety of such tests.
In Chile, a country with a large vaccination operation and used the Chinese Sinopharm vaccine, even though studies spoke of up to 80% effectiveness, the Chilean government had to resort to a third dose because there were peaks of contagions in a population highly vaccinated with two doses. In other words, the declared effectiveness of vaccines, sometimes even by the WHO itself, is not the real picture.
The WHO official also clarified that there is no absolute certainty that a third dose is really necessary, especially when people have already received two doses.
The doctor’s comments refer to the request presented last week by the BioNTech laboratory, creator of the Pfizer vaccine, which claimed that a third dose was necessary to increase the immune response to the Delta strain, which they say is highly contagious.
Instead, the scientist, as well as WHO director Tedros Adhanom Ghebreyesus, called on rich countries that have already administered two doses of the vaccines to donate their vaccines to WHO’s Covax program so that they can ‘equitably distribute’ the vaccines to poorer countries.
“Some countries and regions are actually ordering millions of booster doses before other countries have had supplies to vaccinate their health workers and most vulnerable,” said Tedros Adhanom Ghebreyesus.
Both WHO director Tedros Ghebreyesus and chief scientist Soumya Swaminathan have been embroiled in serious problems that damaged their credibility and that of the agency.
Tedros was accused of covering up the pandemic to please the demands of the Chinese communist regime which is now known to have had data as early as December that the coronavirus could be transmitted between humans but did not report it until it was too late.
Dr. Soumya Swaminathan was criminally sued in her home country by the Indian Bar Association for discouraging the use of Ivermectin in COVID patients, which the lawsuit claims led to deaths that could have been prevented.
If the lawsuit is accepted and the physician is found guilty, she could face the death penalty or life imprisonment.
