Yesterday the alarms of the scientific community were turned on, after it was announced that the coronavirus vaccine that is being developed at the University of Oxford together with the AstraZeneca laboratory he should have stopped his rehearsals, following suspicion of a serious adverse reaction in a volunteer in the UK.
This vaccine is in phase 3 and is considered one of the most effective that is being developed in the world. An AstraZeneca spokesperson said in a statement that the “The company’s standard review process caused a pause in vaccination to allow review of safety data”.
Along these lines, today the chief scientist of the World Health Organization (WHO), Soumya Swaminathan, pointed out that the coronavirus vaccine would not be massively available until 2022: “Many think that at the beginning of next year a panacea will arrive that solves everything, but it will not be like that: there is a long process of evaluation, licensing, manufacturing and distribution ”.
“It is the first time in history that we need billions of doses of a vaccine”said the scientist, adding that risk groups could be immunized in mid-2021.
With this background, today the Minister of Health, Enrique Paris, was consulted on this matter and on whether public policies should be rethought with what this new scenario would be.
“That does not mean that we cannot count on other vaccines. There are many companies that are testing vaccines, several that are already in clinical phase 3. In fact, in Chile there are 3 vaccines that are in clinical phase three or that are going to do their clinical trial here “, said Paris, and stated:”I do not think that we will only have a vaccine in 2022, that is an alarm, I think that for the moment, it is unnecessary and it is not good to create that concern in the population ”.
Regarding the case for which the development of the Oxford vaccine was stopped, he said: “It is an expected adverse effect, which occurs regularly, which is within the possibilities. What this patient had is a transverse myelitis, that is, an inflammation of the spinal cord, probably produced by an interaction between the vaccine virus and the spinal cord ”.
“The President and the team of Health, Foreign Relations, Ministry of Sciences, ISP, Advisory Committee on Vaccines and Immunizations (Cavei) and Vaccine experts are all working so that Chile can have a vaccine in the period that we originally said, that is, in the first quarter of 2021 “, he said, adding:” LThe vaccine will be free and will be initially placed in risk groups ”.
