COVID-19 Vaccination and the Fourth Wave of Pandemic Spread

Abstract

During the first three waves of COVID-19, the focus was on herd immunity through providing vaccinations and applying quarantines. Though, we were unable to prevent the fourth wave of the disease and new variants of the virus were identified. It is believed that quite some people question the safety and quality of existing vaccines and untrust their effectiveness from aside, and violate the quarantine guidelines, such as social distancing, wearing a mask, and other suggested safety procedures from another side. Today, based on scientific research and healthcare scientists’ recommendations, it can be concluded that the most effective measures to prevent COVID-19 are vaccination and self-quarantine.
