The most responsible nurse control in China admit the end of the week that the vacancies that the country has unlocked to combat the pandemic offer a minor protection that others, includes the Pfizer-BioNTech and Modern lasers that are widely distributed in the United States.
China currently has five vacancies in use in its massive munitions campaign, housed by the Coronavac cameraman, manufactured by Sinovac. The Asian giant has distributed tens of thousands of doses abroad, including various countries in Latin America: Brazil, Chile, Mexico and Colombia.
The efficiency of Chinese vacancies oscillates between more than 50% and 80%, as far as companies are concerned, much less than 95% of Pfizer-BioNTech and Modern distributed in the United States.
But scientists say that lowering the risk can be less severe when it comes to medical conditions. Although each vaccine against the covid-19 is unique and can vary in efficacy, the combination of all of them can help create the “collective collective” global necessity to eradicate the pandemic, say public health experts. Anything that exceeds 50% is considered useful, señalando that the vacancies against the flu, for example, have a real efficiency only between 40% and 50%, and are now widely accepted.

How to avoid efficacy
The level of efficacy is usually observed by the number of persons who unroll the covity -19 after receiving the vaccine, in comparison with the number of affected persons when administering a placebo injection, or fiction. The 50% increase in Chinese vacancy rates is not as good as the 95% of Pfizer-BioNTech and Modern.
However, different methods are used in different countries, just as the criteria used to improve the protection of vacancies. Although some vacancies can offer a minor infection, they can be very effective in preventing serious death or death. For example, the Johnson and Johnson vaccine has a general efficacy of 72%, but in the United States the result is an efficacy of 86% against serious illness. On its own, AstraZeneca says its vacancy was 76% effective in reducing the risk of medical malpractice, and 100% against serious malnutrition.
China’s China sinovac covid-19 has an efficiency of 50.7%, following the last dates published last week of the projects carried out in Brazil, at the Instituto Butantan, state property, Sao Paulo. In addition, it is estimated that the efficacy rate of the Sinovac vaccine increases to 62.3 per cent with an interval of more than 21 days between doses, in place of 14 days. Also, there was an 83.7 per cent increase in the prevention of cases that require medical attention.
The monopoly of vacancies
Many governments have been anxious to use Chinese vacancies, and the rich countries of the world are monopolizing vacancies like Pfizer-BioNTech and Modern. The Director-General of the OMS, Tedros Adhanom Ghebreysus, said to the four that one of four people in the rich countries would have received a vacancy, only one in every 500 people in the poorest countries would have received a dose.
Latin America has one of the most vacant travel bags in the world, with only 6.2% receiving at least one dose in South America, up from 45% in Asia and 25% completing all in the United States.
Distribution
In recent weeks, various countries of Latin America have approved the use of coronavac emergence, due in part to the lack of availability of other vacancies. Chile was the first to buy coronavac in October, and has received 10 million doses and has the highest altitude evacuation rate in the country, at 25%. Other countries: Mexico, Brazil and Colombia, Bolivia, Panama, El Salvador, Paraguay and Uruguay.
The situation could increase as the United States reduces the need for Pfizer-BioNTech and Modern vehicles. “United States will buy many more vacancies than those required, so that the emperor will share the excess,” said Szapocznik. “In addition, the United States does not require such vacancies after the vernacular, when the world is vacated”, added.
Prohibition of probes, the minor efficacy of Chinese vaccines could allow the mutations of the virus to propagate, what creates the risk of appearing a new variant more delicate, dijo. “Each has more variants and increases the risk of appearing more dangerous”, dijo.
Transparency
Todavía is relatively ready to evaluate the efficacy of vacancies, which will not be distributed until December, and some countries will not be able to receive any dose. Although it passes the months, appears more informative about the efficiency of the new vacancies that sell in the market.
On the other hand, the dudas are based on the fact that the vacancies in China are not subject to the same scrutiny and levels of transparency as their Western homologues. But the unusual reconciliation on the part of the Chinese authorities whose vacancies could have deficiencies is a signal of a mayor’s transparency.
The Director of the Center for Prevention of Chinese Injuries, Gao Fu, said at a celebratory conference last week that he was studying the possibility of different means of evacuation to increase its efficiency, as well as the possibility of adopting the innovative technology of ARN of the vacancies of Pfizer and Modern.
