The world is anxiously awaiting the development of a vaccine to fight the emerging coronavirus, but what if it is late to find it? Is it impossible to live without it?
The answer to these questions is summarized by Dr. William Hasseltin, a scientist specializing in the human genome, cancer and HIV, in an analysis published by CNN.
The world should not wait for the vaccine, the hope is to coexist and adapt to “wearing masks, washing hands, disinfecting surfaces and social distancing” to become a human behavior by societies as a whole, said Hasseltin, who heads an Axis Health International research center.
He did not rule out the emergence of the vaccine by the end of the year, but he questioned its progress in all stages of development and experiments as required to the fullest extent, indicating that this is a "rare occurrence".
Vaccines do not work as a shield to protect our bodies from viruses, but rather they teach the immune system and train it to recognize the virus and respond quickly to counter it, before it damages the body, which also depends on the immunity of the person himself.
He pointed out what we learned about Corona viruses in total during 6 decades, that even if the immune system can eliminate them, it is still possible that the virus will come back again and cause disease, not to mention that the vaccines are still under development and despite the success of some in the laboratory environment, but they Did not prevent the occurrence of nasal infections, and in one case the vaccine was able to prevent the spread of disease in the lungs, which happened by testing it in monkeys, but despite the similarities with humans, the response of the human body can only be known about its effectiveness after long experiments.
Hasseltin expressed that it is constant until now that some vaccines that are tested in humans have serious side effects, which can stimulate the immune system in the body, but the efficiency and safety of the vaccine must be tested on the older groups as it happens with those who are at an average age of their lives , Whose results may be risky, or it will reveal that older adults require repeated doses of the vaccine.
"Even without a vaccine, there is reason to hope that a medical solution to the crisis will soon be, which we can see as therapeutic drugs for the disease or help the sufferers not spread the disease," he said.
And he confirms that this matter should not be done in isolation from the continued use of human masks, sterilization of different surfaces, and spacing, until the appearance of the drug or vaccine.
He revealed that some experiments on some drugs were able in vitro to stop the spread of the virus through a chemical substance, but it has not been tested in humans yet, and there are experiments on other drugs that can prevent the virus's proteins from adhering to the human cell.
Corona virus infection is close to 12 million people worldwide, with a death toll of approximately 540,000 deaths.
