Since the fight against the new coronavirus is not yet over, I believe we are all interested in "when will there be a vaccine" and "when will there be a cure". Experts in various countries are already conducting various tests in order to develop a new coronavirus vaccine as soon as possible ...... Why is this important? Take the once extremely dangerous "flu" as an example. Today, they still appear seasonally and are still highly contagious, but mankind is no longer panicked because of the emergence of special medicines and vaccines that give us the means to treat and prevent them. Scientists have developed vaccines in different ways, which are important for humans to protect against certain viruses or diseases.
Here's a look at vaccines and why the World Health Organization and health departments everywhere are encouraging people to get vaccinated... Vaccines are not the same as viruses or bacteria. A vaccine is any preparation made by extracting a disease-causing component (e.g., a viral antigenic component) from a bacterium or virus through scientific methods and rigorous procedures, and inactivating or attenuating it so that it loses its ability to cause disease. Common vaccines include inactivated or attenuated microbial suspensions, or microbial products or derivatives. Do vaccines directly kill viruses and bacteria? Vaccines work like training for soldiers. Humans face many diseases and rely primarily on their own immunity to achieve recovery. When a vaccine is injected into the body, it tricks the body into thinking it is under attack by a pathogen, which triggers an immune response.
Later, when the body encounters a real bacterial or viral infection, the immune system can quickly produce enough antibodies to fight off the disease. Sick after vaccination? Because vaccines have an inactivation or attenuation process, the preparation itself has lost its disease-causing ability, and it definitely does not directly inject bacteria or viruses into the body, so it does not cause illness. Misinformation about the efficacy and safety of vaccines sometimes leads some people to misunderstand and be skeptical about vaccination. The truth is that vaccines undergo a great deal of testing and oversight from development to testing to production. This is why vaccine development often takes a long time. The efficacy and safety of vaccines must meet the stringent standards of the World Health Organization and local medical institutions before they can be widely used. Local governments also have mechanisms in place to monitor and follow up on vaccination reports from healthcare workers, so the risk is extremely low.
On the contrary, the chances and dangers of contracting a disease without vaccination are far greater than the risks of vaccination. Do vaccines make diseases go away? Successful vaccination programs can prevent disease, but the infectious agents that cause disease still circulate in some parts of the world. In today's highly interconnected world, these pathogens can cross geographic boundaries and infect unprotected populations. There are two other important reasons to get vaccinated: to protect ourselves and to protect those around us. So, does the "flu shot" really work? Vaccination is more than just a "shot"; by far, "prevention" is the most common method. The point is that a systematic vaccination program can increase the immunity level of the entire population, reduce morbidity, mortality and disability from vaccine-preventable diseases, and eliminate or eradicate vaccine-preventable diseases.
