COVID-19, Vaccine candidates are at an advanced stage and there is hope
The Director General of the World Health Organization, Tedros Adhanom Ghebreyesus, stressed that six candidates for vaccines against COVID-19 are in an advanced stage, so there are hopes that there may soon be immunization of the population against COVID. -19.
The expert, who earlier this week warned that there might not be a panacea against COVID-19, clarified that the fact that some of the possible vaccines are in the third phase of clinical trials is encouraging, but stressed that the final results of these tests.
More than 140 laboratories in the world are developing vaccines, although six of them in countries such as the US, China, the United Kingdom or Russia are in the third and final phase of trials, in which the candidates are tested on thousands of people in search of possible adverse side effects.
