A possible vaccine developed by the pharmaceutical company Inovio, with the support of the Bill and Melinda Gates Foundation, has already received formal approval to be tested in humans.
This is a move towards a second phase, after the Moderna laboratory in Massachusetts shipped a first batch of test vaccines in mid-March.
Even if these vaccines were confirmed to be effective after the procedures, it would take up to one year and 18 months for formal approval to be applied to the public.
Without taking into account the permits that should be approved in each of the countries before the vaccine can be sold to the public or distributed in health centers.
Experts predicted several months ago that creating the vaccine will cost about $ 1 billion dollars (USD), and the treatment would cost about $ 1,000 (USD) more per person.
Ideally, each government should be responsible for distributing the vaccine free of charge to citizens.
But with such a high cost, in countries like Latin Americans it would be difficult to pay for the millions of supplies necessary to apply to the entire population.
