Natural immunity is not as strong as we may think towards the fight of covid-19. Before the arrival of the recommended vaccines, the pandemic almost killed everyone. Many people lost their lives and those of loved ones because of the disease. There were no clear treatment methods effective towards the disease. Since the vaccine was approved and ready to be used by humans the numbers seem to decrease. This is because the immunity levels changed and now the human body was ready to fight the disease. For this reason the center for disease control CDC and world health organization WHO and all other health organizations urge and make it mandatory that people aged 12 years and above should get the covid-19 vaccinations to make the body ready and equipped to fight the pandemic (Baraniuk, C. 2021)
Even after the vaccinations, there are people still getting infected. This is termed the Breakthrough infection which happens when fully vaccinated people are infected by the virus. They are occurring at low percentages. The vaccine is not 100% effective considering some preexisting conditions and illnesses. After vaccinations, people are advised to stay in clear areas with high infection rates without taking the required measures for protection, like wearing a mask or avoiding crowded places, the chances of getting ill are still there. This person can still spread the disease to others. Isolation would be best in case a person is sick. More precautionary measures should be taken and people are requested to not be negligent once they get the vaccine. However, sick people will require less treatment compared to before when one needed an ICU facility or ventilator.
It’s safe to conclude that vaccination is better than natural immunity. The numbers don’t lie and the safety of the world I even felt more with everybody getting the vaccine.
