The East African island nation of Seychelles has the highest vaccination rate in the world, with more than 60% of its nationals having received two doses of vaccine against the CCA virus (Wuhan virus and New Coronavirus). Recently, the country has experienced a surge in confirmed cases and has the highest rate of infection in the world. Concerns about the effectiveness of the Chinese vaccine have been raised by the fact that the country is mainly vaccinated with the Chinese “national” vaccine.
According to the Voice of America, Seychelles released data on May 13 showing that it has more than 2,700 active cases among its approximately 100,000 nationals, a much higher rate of infection than India. Of those in Seychelles who have received two doses of the vaccine, 57 percent received the Chinese “Sinopharm” vaccine and 43 percent received the AstraZeneca vaccine.
This underscores the importance of vaccine choice, the report said, citing a New York Times report.
Citing data from the Seychelles Ministry of Health, the paper said 37 percent of newly diagnosed infections had completed two doses of the vaccine, but the ministry did not say how many of those were the “national” vaccine.
Breakthrough infections are not uncommon
Epidemiologist Chenglong Liu, a researcher at Georgetown University School of Medicine, told the Voice of America that so-called “vaccine breakthrough cases,” as defined by the CDC, are not uncommon. This means that although people who have been vaccinated are much less likely to get sick, it can still happen.
As of April 26, 2021, more than 95 million Americans have been fully vaccinated with the New Crown vaccine,” said Cheng-Long Liu. Of those 95 million people, 9,245 breakthrough infections have been reported to the CDC. Of these breakthrough cases, 27% were asymptomatic infections, 9% were hospitalized after infection, and 1% of those infected died.”
The two main vaccinations in the U.S. are the Modena and Pfizer New Crown vaccines, both of which have been shown to be around 95% effective in clinical trials.
In fact, all existing vaccines for the CCP virus in use have had vaccine breakthrough infections. Another Sinovac vaccine, produced in China, had a breakthrough infection in the Philippines in March, and more than two dozen Thai women’s national team athletes are believed to have tested positive for the virus after receiving their first dose of Sinovac. The first dose of “Kexing” vaccine is also believed to have tested positive in more than 20 people.
Experts: Phase III clinical data missing for “national” vaccine
Fifty-seven percent of the vaccinated population in Seychelles received the WHO-approved “national” vaccine for emergency use, so does this mean that the “national” vaccine is the culprit?
Dr. Amesh A. Adalja, MD, a senior scholar at the Johns Hopkins University Center for Health Care Safety, told VOA that the biggest concern is that the majority of people in Seychelles are receiving the Chinese “national” vaccine, for which no phase III clinical data have been released. data.
Adalia said, “Because we don’t have peer-reviewed publications on the results of the phase III clinical trials for this vaccine, it may not be the best vaccine.”
“The “National” vaccine is far less effective than Modena and Pfizer
In fact, the two vaccines administered in the Seychelles, Sinopharm and AstraZeneca, despite both having been reviewed by independent experts and recommended for global emergency use by the World Health Organization, are both far less effective than the vaccines commonly administered in the United States “Modena” and “Pfizer”.
According to the data published by the World Health Organization, the effectiveness of the AstraZeneca vaccine in preventing symptomatic infections is 76%, while the Chinese medicine vaccine was previously approved for use in China, Pakistan and the United Arab Emirates, and the comprehensive assessment by an independent WHO expert group The results were that the effectiveness rate for symptomatic infections and hospitalizations was approximately 79% for all age groups. According to WHO criteria, an efficacy rate of 50% or more is considered effective and can be recommended for inclusion on the emergency vaccine list.
Although the WHO has recently approved the “national” vaccine and placed it on the emergency use list, it is not the most effective, said Dr. Adalia of Hopkins University. “Even the director of the Chinese Center for Disease Control and Prevention himself has said that the Chinese vaccine is not as effective as other vaccines.”
Data released by the Butantan Institute in São Paulo, Brazil, in January showed that the overall effectiveness of the Chinese-made Kexing vaccine was only 50.4 percent. Much lower than the previously announced 78%. It is not yet known whether the efficiency of the “national” vaccine is also overestimated.
Since the Seychelles government did not provide the percentage of people with breakthrough infections who received either the “Kokusai” or “AstraZeneca” vaccine, or the specific timing of vaccination and new infections, the WHO is further investigating the breakthrough infection data for Seychelles. WHO is investigating further data on breakthrough infections in Seychelles.
