Entornointeligente.com / Despite getting vaccinated against COVID-19, Colin Powell remained vulnerable to the virus because of his advanced age and history of cancer, highlighting the continued risk to many until more of the population is immunised.
Powell, a four-star general who became the first Black secretary of state and chairman of the Joint Chiefs of Staff, died on Monday from complications of COVID-19. Powell, 84, had been treated over the past few years for multiple myeloma, a blood cancer that impairs the body’s ability to fight infections – and to respond well to vaccines.
The COVID-19 vaccines are highly effective against hospitalisation and death, and the unvaccinated are about 11 times more likely to die from the coronavirus. But they are not perfect, and experts stress that widespread vaccination is critical to give an added layer of protection to the most vulnerable.
“The more people that are vaccinated, the less we have viral spreading in the community, the less chances of people like him getting infected to begin with,” said Dr Mangala Narasimhan, chief of critical care at Northwell Health in New York.
Moreover, people with weakened immune systems because of illnesses like cancer – or cancer treatments – don’t always get the same level of protection from vaccinations as healthier people. Several studies have found as few as 45 per cent of people with multiple myeloma may develop protective levels of coronavirus-fighting antibodies after getting the vaccine.
