Accelerated vaccination and new concerns

19 Jul

Vaccination accelerated in July as was the optimistic expectation, the fall in infections and deaths is still very slow and the new waves of infection in countries in the region such as Chile and Argentina light a warning sign, Peru was already in high numbers and some countries in Europe, such as Russia, also show that the Epidemic is far from over.

Argentina reached on Wednesday (14/7) the symbolic mark of 100,000 deaths, high for a population of 44.5 million inhabitants, and entered a new lockdown, with results already containing the new high, the numbers in week fell again.

Brazil like Argentina reaches the number of vaccinated 16% and 11% respectively, while the first dose in Brazil reaches 44.5% and Argentina 45% (see chart above), the next numbers suggest greater attention to the possibility of a new ascending curve, it would be a greater expansion of the delta variant, climatic factors (Chile and Argentina are colder) or even a variant called lambda , and the effectiveness of the Russian Sputnik is questioned.

The lambda variant detected in Peru is frightening, called C.37, its preliminary studies indicate greater lethality and the ability to circumvent vaccines is serious. Researcher Pablo Tsukayama, coordinator of the Microbial Genetics laboratory at the Cayetano Heredia de Lima University, detected that the variant it is already 100% of the infected cases in Peru as of April 2021.

The lack of open data hinders the research, the Ministry of Health of Peru does not disclose it and Professor Tsukayama is one of those protesting this lack of access.

Another issue of concern is the lack of scientific data on the effectiveness of vaccination for the new variants, there are many people who make statements trying to compromise, but do not present clear scientific studies, for example, on new variants such as lambda.

One of these studies, reported by the newspaper El País on July 11, is by Chilean virology Ricardo Soto Rifo, who focused on the CoronaVac vaccine, the main one used in Chile, in a group of volunteer health workers who discovered that lambda presents “increased capacity for infection and immune escape against neutralizing antibodies”, the extent of such loss remains to be clarified.

Another study pointing out in El País is that of the Pfizer and Moderna vaccine, from the University of New York, pointing out that the results were “relatively lower”, but Professor Tsukayma makes a less than encouraging observation: “It is practically impossible to predict how a virus will suffer mutation”, but reducing transmission is possible through vaccines and this is effective.
