Comparative effectiveness of covid-19 vaccines is a research study that includes 23 cases of commonly used covid-19 vaccines administered in Pakistan. The data was collected through semi-structured interviews in tertiary healthcare hospitals in the Hazara region. The study utilized post- vaccination relapse of disease or breakthrough infections as criteria to assess the comparative effectiveness of covid-19 vaccines. The data was analyzed using SPSS and Microsoft Excel-2016. Results suggested that Pfizer was most effective to prevent breakthrough infection and relapse of disease, while Sputnik-V was most effective to reduce the severity of symptoms on relapse. Investigate SARS-CoV-2 breakthrough infections among healthcare workers who received the COVID-19 vaccine to identify trends or clustering in patient characteristics, the administered vaccine, and their comparative effectiveness to prevent relapse and severity of symptoms.


Comparative Effectiveness
The data analysis using SPSS and Microsoft Excel-365. suggests that the majority (95%) of the HCWs who reported clinical symptoms of breakthrough infection had either severe fever (100%) New olfactoryy disorder (100%) and new taste disorder (100%) while 90% of the HCWs had >3 sever and moderate symptoms. The most frequent symptoms included fever (100%), cough (60%), headache (100%), malaise (60%), sore throat (70%), runny nose (70%), and shortness of breath (90%).

Individual Vaccine Analysis
Individual vaccine analysis suggested that most breakthrough infections occurred with AstraZeneca 1/3 (33.3%) followed by Sinovac 3/16 (21.7%), Sputnik-V 1/4 (25%), and Pfizer 0/1 (0%). A comparison of the vaccine based on the percentage of relapse of breakthrough infections suggests that
Pfizer was most effective in preventing post-vaccination relapse of disease while AstraZeneca was least effective in the population studied. Most relapse or breakthrough infections occurred after the first dose 3/5 (60%) while 2/5 (40%) after the second dose. The data on effectiveness for Pfizer is currently limited due to a shortage of vaccines in-country online foreign visitors are allowed to take this vaccine.

Relapse after Dose number

In conclusion, the current report reconfirms the possibility of post-vaccination COVID-19 infection among HCWs. Although the results cannot be generalized because of limited population inclusion and neglecting the other elements including individual condition, rate of exposure, underlying health conditions, and medications. A comparison of vaccine effectiveness based on clinical symptoms on relapse shows that all vaccine is equally effective to reduce the severity of symptoms in a post- vaccination relapse of disease. Sputnik-v was found more effective in reducing the severity of the new olfactory disorder in a patient with a relapse of the disease as well as it reduces the severity of all other symptoms compared to other alternatives.
