Why HIV was created faster than cancer

Effective COVID-19 vaccines were developed within a year. But half a century after the country declared war on cancer, 40 years after it was diagnosed with HIV / AIDS, there is no way to prevent the disease, or many more.

Why? Biology and time, scientists say.

How can effective COVID-19 vaccines be developed within a year when there is no way to prevent cancer or HIV / AIDS and many other deadly diseases after decades of trying?

COVID-19 and the virus that causes it, according to many experts, were easy targets, and came at a time when scientists were well prepared to respond.

“COVID-19 can lead to a very, very bad disease, and it can spread rapidly and therefore cause a global epidemic – but as far as the immune system is concerned, it’s really some kind of wimpy,” said Dr. Dan Burroughs, who helped Johnson & Johnson’s development. COVID-19 vaccine from his laboratory at Harvard University.

COVD-19 can be easily eliminated by the human immune system, while none of the 38 million people infected with HIV for four decades have been completely free of the virus, said Barroch, who has been working on the HIV vaccine for 16 years.

“The virus has developed its own tricks to bypass the immune system, so it cannot be eliminated by the normal human body, and it makes vaccine development very difficult,” he said of HIV. “These are basic scientific differences.”

SARS-CoV-2, which causes COVID-19, is a beautiful genetic virus that is made up of single strands of genetic code and is dotted with spike protein on the outside, giving the virus its unique crowned profile to the corona virus family.

Harvard D.H. says the HIV virus has a rather smooth surface. Said Dr. Roger Shapiro, an epidemiologist at the San School of Public Health.

“It’s very barren on the surface of HIV,” he said, which means it has fewer goals to target vaccine developers.

Targets with HIV are hidden from the immune system, Shapiro said.

COVID- follows some cells that control the lungs, while elsewhere, HIV attacks the immune system, he said. “Cells are fighting HIV to protect us.

In addition, HIV is changing very fast.

“The variation we talk about in COVID is nothing compared to the variation we see with HIV,” Shapiro said. Imagine for a second you were transposed into the karmic driven world of COVID-19.
