During the peak of the COVID-19 pandemic, heightened restrictions coupled with personal health and preventive behaviors protect the public from acquiring the infection before the provision of COVID-19 vaccines. However, as COVID-19 vaccination becomes available to the public, there is an observable weakening of personal health and preventive behaviors as the restrictions weaken. This observation is important for students as they are now more exposed as face-to-face classes are being established again. In this study, we investigate if there is a significant change in COVID-19 related behaviors before and after COVID-19 vaccination among College of Medical Laboratory Science (CMLS) students of De La Salle Medical and Health Sciences Institute (DLSMHSI). We conducted a survey among 263 vaccinated students out of 808 total vaccinated students from first year to fourth year students using stratified random sampling for selecting the respondents, proportionate sampling for determining the sample size, and simple random sampling for determining the respondents per stratum. To maximize our results’ capacity to correlate with our objective, we embed quantitative and cross-sectional research design. Our analysis implied that all variables of COVID-19 related behaviors we measured significantly changed after COVID-19 vaccination from their behavior before COVID-19 vaccination. Additionally, only the proper handwashing and wearing of face masks remained the same after having COVID-19 vaccination. Based on the findings, the researchers recommend that the concerned institution continues establishing health protocols for students to reduce potential transmission of SARS-CoV-2. As some COVID-19-related behaviors begin to deteriorate, the likelihood of viral transmission may increase.
