These are the first people to be vaccinated, according to John Hopkins.

However, even when available, this vaccine will not be in the amount needed for the entire world population. To vaccinate, everyone must spend months.

Eric Toner, the person responsible for the distribution of vaccines of John Hopkins University, says: “We don't need a perfect vaccine. A good” is enough to achieve immunity.

In 2009, H1N1 flu, or swine flu, has given us sufficient experience in the vaccine's distribution strategy. On that occasion, since the virus affected young people more, it was recommended that those between 6 months and 24 years of age be vaccinated first, as well as other endangered groups.

In view of this experience, John Hopkins University gives its advice on the distribution of the Cavido-19 vaccine when it is ready. In a 46-page document, it says that vaccine should be done on two levels.

Level 1: Absolute priority

Members of teams facing pandemic first: medical staff

Groups and individuals of essential social services: public transportation, food production and distribution, and educators.

The most endangered persons, pregnant women and social headquarters staff.

Level 2: depending on the availability of the vaccine

Pharmacists and Doctors Who Cure Those Without Coronavirus

People who have trouble access to services in case they get sick -- residents of remote and remote areas, with undeveloped health infrastructure.

Other members of basic social services: media communication, police, firefighters. / A2 CNN
