It’s almost two years since covid 19 hit the world. The pandemic has shaken every person and a solution had to be found and thus the effective vaccines to help protect the people from the virus and the violent symptoms. These vaccines are all safe to be used by everybody. However, there may be some side effects that are to be expected and normal. After vaccination, the body takes around two weeks to build immunity to the virus. When a person gets vaccinated they can resume daily activities (Iwasaki A & Omer S, 2020)

 Vaccines are intended to provide natural immunity to the body and help fight all the severe symptoms reducing the effects the virus may have on the respiratory system. 

Since the white blood cells are responsible to fight the virus at times there is a need for help in fighting the stronger diseases. The body ought to be naturally prepared. The vaccine helps in these preparations. The vaccine aims to provide more power and strength to the white blood cells. When a person is not vaccinated the body can take some time before it generates fighters responsible for the virus. Since there are no soldiers, the person gets sicker more quickly. With the vaccine, there is an introduction of a look-alike of the virus to ensure that the responsible white blood cells get to be familiar with the virus and develop the responsible antigens to fight when the real virus comes. The side effect that comes with the vaccine is the body is in process of getting its immunity towards the virus (Iwasaki A & Omer S, 2020).  Despite there being different vaccines they work the same way. Some may require a double shot with a difference of twelve weeks and others like the Johnson &Johnson’s Jansen vaccine one shot is enough for full protection. 

 It’s safe for all people to get the vaccine and make the world a safer place for everybody and so that all normal activities can resume.
