China starts vaccinating thousands teachers supermarket employees against coronavirus despite no vaccine has passed the last stage of testing: There are months left before the population can be vaccinated in Europe or the United States, and the horizon is even further when one thinks of a widespread vaccination that could leave the pandemic in a bad memory.

According to the information managed by the Ministry of Health, the vaccine of AstraZeneca and the University of Oxford will arrive in Spain in December, and if all goes well it will be possible to vaccinate 3 million people of risk groups in the last days of 2020 or the first days of 2021.

Other countries seem to have moved ahead and are moving much faster. This is the case in China, which has already announced that its vaccine will be available for sale in November, so they could really be close to a massive vaccination.

In fact, China has been vaccinating a large part of its population for some time now, at least since last May, when they released the results of a study confirming the effectiveness of their vaccine. Without going any further, in early September the authorities of the Asian giant acknowledged having vaccinated "hundreds of thousands of people" with at least 2 different vaccines.

The first to receive this remedy were workers of state-owned enterprises, then did the same with some government officials, later came the turn of the vaccine developers themselves, and now it is going to extend to other workers who consider themselves essential, such as teachers, supermarket employees or entrepreneurs traveling to risk areas, according to the New York Times.

Although preliminary results indicate that Chinese vaccines are safe and generate robust immunity, the fact is that administering them to a large part of the population without having passed all phases and protocols carries risks whose scope is yet to be determined, explains the same publication of the American Journal.

This is mainly due to 2 reasons: long-term side effects are unknown and could emerge in the coming months, and it can also happen that the vaccine is not as effective as it seems and generate a false sense of security, causing a wave of new infections.

To get an idea of the strict protocols in these investigations it is enough to review the development of the vaccine from the University of Oxford and AstraZeneca, which a few weeks ago had to temporarily stop testing to study the case of a rare disease that had just suffered one of the volunteers.

Finally, the trial continued a few days later, after finding that the disease was not caused by the vaccine. It is not clear that China is following such a strict method during its investigation.

Vaccine manufacturers and Chinese health authorities have always claimed that participation in trials is voluntary, however, the New York Times points out the possibility that all these people have not been properly informed of possible adverse effects.

Many experts believe that trying to move ahead too quickly in the vaccine race could be detrimental, as it would result in ineffective remedies. WHO itself has already warned that approved vaccines should have between 30 and 50 per cent effectiveness, and that further safety measures should still be taken to end the pandemic.
