Vaccines are old but still successful: A compromising confrontation

Vaccines are old but still successful: A compromising confrontation

Introduction

More than a year has passed since the coronavirus pandemic, during this time we have witnessed lifestyle changes, the destruction of many businesses, harm to the education sector, economic problems of governments, pressure on countries' health systems and, most importantly, widespread deaths.
 Many developed countries were undertaken a nationwide quarantine with an extensive screening at the community level and adherence to protection protocols to prevent the spread of COVID-19 in their community; despite advantages of these measurements, after breaking the restrictions, the epidemic flared up. On the other hand, due to the damage caused by these quarantines, non-compliance with these laws by some individuals, and pressure on governments, permanent restrictions were not possible. 
These complications have forced governments to find a solution. Discovering or making an effective and definitive medication might take many years; so, what is the best solution?
The researchers followed the same path that had previously controlled or even eradicated many infectious diseases. vaccine! 
It did not take long for the advancement of biotechnology, along with the availability of vast financial resources and manpower, to lead to the development of vaccines with remarkable effectiveness that gave people hope. Institutions and health and pharmaceutical organizations reviewed the information, quality, safety, and effectiveness of different vaccines carefully; the results were quite accurate and reliable; meanwhile, the advice of these institutions is:
 Do not wait! Inject any available approved vaccine. 
Now the way is clear: extended vaccination

Body 
In countries with widespread vaccination, the situation has changed, the number of hospitalizations has dropped dramatically, COVID-19 mortality among vaccinated people was reduced near to zero, and restrictions have been gradually removed.
In contrast, countries that postponed vaccinations continued to tolerate the burden of the disease. These countries initially lost a significant number of physicians and medical personnel due to COVID-19. However, some of them started vaccination from the medical staff and were able to protect the vaccinated people. In the latest report from these countries, the authorities reported zero deaths from COVID-19 among fully vaccinated nurses, and all infected cases had mild COVID-19 and did not require hospitalization.

 Ever since the vaccine was developed, the new generation of high-efficacy mRNA vaccines is of particular importance, although critics of the rapid development of this type of vaccine have argued that it is the first of its kind to be widely used. It is noteworthy that the first and only corona vaccine that has so far been fully licensed by a reputable scientific authority was the mRNA vaccine. (2) These vaccines have also been advised by reputable scientific bodies such as the US Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC) for adolescents.

Some countries, such as the United Kingdom and Israel, inject boosters into their citizens, the FDA recently approved the injection of a third dose of the vaccine for people over 65 years and also high-risk people. (5) The latest serological data from a study in Israel declared that people who get the third dose of the vaccine are 10 times more immune to COVID-19 compared to those who get only two doses. The study reported that the third dose had the fewest side effects at all ages. (6)
