The initial production of vaccines against Covid-19 should go to high-risk groups, so young people will have to wait until 2022, said on Wednesday the chief scientist of the World Health Organization (WHO), Soumya. Swaminathan.
“People think that on January 1 there will be a vaccine and that things will return to normal, but things will not be like that. Nobody has ever produced vaccines in the volumes that will be needed, so in 2021 we hope to have vaccines, but in a limited quantity ”, he clarified.
The consensus is that the first vaccinated are the health workers who are on the front line of the fight against the pandemic and then it is passed on to the elderly and the most vulnerable people.
“A young and healthy person will have to wait until 2022 to be vaccinated,” said the scientist.

A dozen potential vaccines are currently in phase 3 clinical trials; that is, they are being inoculated in groups of approximately 30,000 people in places where the coronavirus continues to circulate intensely.
This phase of clinical trials is used to verify the efficacy of the vaccine and to rule out serious side effects.
In total, forty vaccine trials are in one of the three phases of clinical trials and 200 are in laboratory tests, which is a clear indicator of the interest that the pharmaceutical and biotechnology sector has in finding the right formula.
“Until we have the results of phase 3 we will not know which and how many of these vaccines will be safe, effective and will protect for a long period,” said Swaminathan.
The representative of the WHO anticipated that these results could be ready at the beginning of next year, after which it will have to comply with the regulations for the approval of one or more vaccines.
