A state of hope and optimism prevailed after the announcement. These are the promising results against the emerging corona virus, which has infected more than 53 million people and claimed the lives of more than 1.3 million more.
While the good news about a Covid-19 vaccine carried a wave of hope and optimism, skepticism across the board may make the viability of the vaccines even the most effective among them, without benefit, as the department’s official warned. vaccination of the World Health Organization.
“The vaccine that remains in a refrigerator or in a refrigerator or on a shelf without being used does not contribute to the elimination of this pandemic,” said Catherine O’Brien, in an interview with Agence France-Presse.
He also said that these results, while preliminary, are “very important,” and expressed hope that data will be released for several other vaccines that are in the final stage of human testing.
And he stressed that if the complete data shows “that one or more vaccines are very effective, it will be good news for us to enrich their arsenal with a new tool in the fight against the pandemic.”
But he expressed grave concern about misinformation and conspiracy theories that are bolstering the ranks against vaccination, while the pandemic remains largely unchecked and has resulted in more than 1.3 million deaths.
And he emphasized that “confidence must be strengthened that the World Health Organization will not make concessions in terms of safety and effectiveness of the vaccines it evaluates.”
‘Massive logistics challenge’
Also, O’Brien, a physician, said there are important things that are not yet clear about the vaccines that are being developed, like how long they provide the protection they provide. And there is also a very important question: “Does the probability of transmitting the disease to another person change?”
The World Health Organization is counting on the availability of these vaccines in the coming months, but is preparing as of now for the enormous logistical challenge of vaccinating billions of people as quickly as possible.
The organization made recommendations to provide the first dose of the vaccine to those most at risk of infection.
20% of the population of each country is vaccinated.
In turn, O’Brien explained, “the goal is for each country to be able to vaccinate 20% of its population by the end of 2021, which in fact will contribute to responding to the needs of medical personnel and residents who have As the supply continues to increase, we expect to receive a much larger number of doses in 2022. “
The availability of the vaccine will also depend on the possibility of producing the vaccine in large quantities, storing it under favorable conditions and transporting it, sometimes keeping it frozen or at low temperatures and finding enough personnel to inject it.
Focus on distribution
The WHO official added: “A vaccine is very effective, safe and can be produced for public health only if it effectively reaches the people who should be protected and only if it is widely used among the population.” This is the next challenge before us. “
“In fact, for vaccines to have a real effect, we must focus on distribution,” he added.
And the American laboratories, “Pfizer” and German “Bayontek”, announced, this Monday, a vaccine that has developed an effective rate of 90%, according to the preliminary results of the third phase trials of this vaccine, which include more of 40 thousand people.
They also explained that protection against the coronavirus is achieved at a high rate 28 days after taking the first dose, and that it is completed only one week after the second dose.
