How Long that a SARS ‑CoV‑2 Variant Delay Impacts Required Period to Achieve Herd Immunity?
Dear Editor, The coronavirus disease (COVID ‑19) vaccine is the present preventive tool for COVID‑19 containment. Mass immunization is required for achieving herd immunity. If herd immunity is reached, a successful COVID‑19 containment is expected.[1,2] In general, the targeted population size that herd immunity will achieve is mainly b ased on the basic reproduction number and is generally estimated as 75%.[1,2] Regarding the required period to achieve the impact of herd immunity depends on many facts including the targeted population size (unit: %), base local infection prevalence (unit: %), vaccination rate (unit:...

Cancerous Patient, COVID ‑19 Vaccination, Blood Viscosity and Stroke‑Like Complication
Dear Editor, The coronavirus disease 2019 (COVID ‑19) vaccine is the hope for the management of the COVID‑19 outbreak. At present, the COVID‑19 vaccine is already in use in several countries. An important concern is the adverse effect of vaccination. There are many possible adverse effects of the COVID‑19 vaccine including vascular complic ation. The possible neurological complication due to the COVID‑19 vaccine is an important present consideration.[1] There are many recent reports on neurological incidences including stroke‑like complication after vaccination.

COVID ‑19 Pandemic Infection Control and Instantaneous Contact Tracing Using Mobile Phone Apps
Dear Editor, COVID ‑19 is still a global challenge to be managed. This infection has caused worldwide crises resulting in more than 104 million infected persons worldwide. As disease containment depends on several factors, a strict regimen for disease controlling and surveillance is necessary. For controlling the ou tbreak, case identification is needed. When there is a newly detected case, identification of at‑risk persons in contact with the patient is needed and it might be sometimes difficult.

Positive Predictive Value of SARS ‑CoV‑2 Spike Protein Antibody Test after COVID‑19 Vaccination Policies
Dear Editor,Mendicino and Moretti provided very useful ideas on using “tests for the detection of antibodies to SARS‑CoV‑2.”[1] Mendicino and Moretti discussed on effect of local prevalence of coronavirus disease (COVID) on diagnostic property of the test and concluded that “knowledge about the advantages and limitations of each test will help to select the most appropriate one to each clinical and epidemiological situation, and to an adequate interpretation of the results.” (Source: International Journal of Preventive Medicine)

COVID ‑19, Vaccination, Multisystem Inflammatory Syndrome, Aneurysm, Screening and Post Vaccination Death
Dear Editor, COVID ‑19 vaccine is the preventive tool against COVID‑19. The safety of the new vaccine is the present issue for research. For any vaccination, postvaccination death requires a good investigation. An interesting emerging problem on postvaccination death due to ruptured aneurysms is an interesting obs ervation. The primary investigation by local public health administrators usually reveals no association (for example, see https://healthserv.net/en9417). Theoretically, COVID‑19 might cause aberration in homoeostatic system. The clinical association with an aneurysm is also reported. (Source: International...
