Vaccination marks huge differences between countries in mortality from coronavirus

Mortality from coronavirus in Spain has increased in recent days, as a result of the fifth wave of infections, until it equaled the peak reached during the fourth wave, when the vaccination campaign was taking its first steps. However, despite the similar mortality, the difference in fatality between the two waves is notable since the number of positive cases has now been triple than then.

In the ola primaveral, the incidence did not reach 250 cases per 100,000 inhabitants in the last 14 days; while in this summer wave, has exceeded 750, according to data from the European Center for Disease Prevention and Control (ECDC, for its acronym

in English), which allows comparison between countries. Despite tripling infections, mortality is significantly lower. In May, the weekly mortality rate was around 25 deaths per 100,000 inhabitants in the last 14 days; While now, with triple the number of infections, it stands at 11, with data from the ECDC until August 1. The mortality of this fifth wave has not yet reached its peak, although, with hospitalizations already on the decline, everything indicates that it will be far from the levels reached in previous waves.

In Spain, the accumulated incidence in this fifth wave has been higher than that of the second wave, last autumn; However, then, without any vaccine, the mortality rate was ten times higher than the current one, up to 105 deaths per 100,000 inhabitants in the last 14 days. Mortality has decreased thanks to the effect of vaccines, as has happened in other countries that have already achieved wide coverage, unlike what happens in the world without protection against the virus.

Countries with vaccine, countries without vaccine

In United Kingdom, also with a high level of infections this summer after the lifting of restrictions, the situation is identical to the Spanish one. The British advanced faster at the beginning of the vaccination campaign; By the end of April they had already covered 20% of their population, the highest risk, a level that Spain did not reach until a month later, according to data from ‘Our World in Data’, a repository of the University of Oxford with international statistics about the pandemic. In United States, which reached that level in early April, has also drastically decreased mortality compared to the effects of previous waves. Vaccine coverage in Spain, close to 60% with the complete regimen, is already higher than them, with less acceptance of inoculation by the population.

On the opposite side, the situation has barely changed for countries that have not yet had access to sufficient doses to protect their population against the coronavirus. Without vaccines, the rise in the number of infections has inevitably resulted in increased mortality. In some countries, like Tunisia, Indonesia O Namibia, with vaccine coverage still below 10% of the population, even with unprecedented levels of infections throughout the pandemic. In overcrowded Indonesia, with low incidences throughout the pandemic, the Delta variant has multiplied the dimension of the health crisis.

In countries still with insufficient percentages of vaccination, such as Colombia, which reached that 20% in mid-July, or Russia Y Argentina, still below that figure, mortality remains high, awaiting greater coverage that reduces the lethality of the next waves.

World vaccination

Although a quarter of the world’s population has already been inoculated at least once against the coronavirus, the distribution is uneven across regions of the globe. In Africa, less than 4% have received at least one dose, while in Europe it is 50%, according to data from ‘Our World in Data’. In North America, it is 49%, 38% with the full guideline; while in South America, 45% have one dose and 21% already have two. In Asia, coverage with at least one dose has reached 29% of its population.
