“…4 ) and it was studied [ 18 ]. Studies [ 19 , 20 ] also claim that the effectiveness of the vaccine has been evaluated in the real world. For instance, according to the research of Mirahmadizadeh et al [ 19 ], indicated that this vaccine prevents hospitalization and death by 86.4%, and 98.3%, respectively.…”

“…The occurrence of some cases of breakthrough infection, hospitalizations, and deaths were reported after COVID-19 vaccination [8]. A cohort study conducted in Iran revealed that the incidence rates of COVID-19, hospitalization, and death following vaccination were 528.2, 55.8, and 4.1 per 1,000,000 person-days, respectively [8]. Another study conducted in India on vaccinated individuals showed that breakthrough infections occurred in 7.91% of cases, with older individuals (≥61 years) and males being at higher risk [9].…”

“…Inactivated vaccines (using Vero Cell) had the lowest effectiveness. Diabetes and respiratory, cardiac, and renal diseases as well as neurological and mental disorders were associated with a higher risk of contracting COVID-19 after vaccination [8]. According to a study conducted in France, the likelihood of being hospitalized due to COVID-19 increases gradually with age, with the 85-89-year age group being four times more at risk than the group aged 45-54 years [12].…”

Breakthrough Infection and Death after COVID-19 Vaccination: A Physics Perspective

The largest universal immunization in history has occurred as a result of the COVID-19 pandemic. The developed COVID-19 vaccines have been shown to provide protection against severe forms of COVID-19 by inducing anti-spike neutralizing antibodies. It has been found that individuals who have not been vaccinated against COVID-19 were more likely to contract the virus during a period when the Delta variant was dominant, as compared to those who have received the complete dose of the vaccine, irrespective of the variant. However, there is no notable disparity in the likelihood of hospitalization, requirement for mechanical ventilation, or mortality between the two groups once infected. Nevertheless, those who are unvaccinated may require additional oxygen support. There are reports indicating unfavorable health effects, ranging from transient thyroid dysfunction to death following vaccination. In addition, some people are susceptible to SARS-CoV-2 infection despite they have immunized with the COVID-19 vaccine. Given all these considerations, several key factors should be better understood and considered to enable us to even more successfully manage future pandemics breakthrough infections. The effectiveness of physical treatment methods, e.g., Low Dose Radiation Therapy (LDRT) should be compared to pharmacological treatments.

“…Lack of paying enough attention to this challenge can create high economic, political, and social threats for the country at the regional and global levels. The protection of some vaccines used in Iran has not been very high, and the infection rate after vaccination for COVID-19 has been relatively high (5). Therefore, more efficient and effective vaccines into the na-tional vaccination program for COVID-19 can be considered by health policymakers (5).…”
