In order to impart immunity against SARS COV 2 in the community, the oil rich countries of the Gulf Cooperation Council (GCC) provided citizens and expatriates with free vaccination. Different types of vaccination brands were utilized for this purpose. The purpose of this study is to determine the efficacy of the different types of vaccinations used. This is an observational analytical case study of one Bahraini family who were vaccinated with 1st, 2nd or no dose. Out of 22 double dose recipients of SARS COV2 vaccine, 20 were infected. Those 20 were vaccinated against SARS COV 2 using Sinopharm, the rest (2) were in direct contact with the source but were vaccinated against SARS COV 2 using other type of vaccine. Out of 26 single dose recipients of Sinopharm vaccine, 23 were infected. The other three were not in direct contact with the infected source. Social gathering has been the main source of transmission. The infection has been mild with headache, chest pain. From 20 cases with double dose vaccinations only one had a lung infection and needed hospitalization. Out of 23 cases with single dose vaccinations 10 were hospitalized due to lung infections. All family members who were not vaccinated were infected, three were hospitalized one of which was deceased due to diabetes mellitus complications. Sinopharm provides partial protection against SARS COV 2 infection. That might be due to lack of its potential to detect recent variations in the protein structure of spike(S) protein of virus. • Sinopharm did not provide full protection during recent SARS CoV 2 outbreak in Bahrain. • Bahrain has generously contributed in the 3rd clinical trials for Sinopharm vaccine. • Majority have chosen Sinopharm though 5 types of vaccines were freely vailable • Periodical update of vaccines under EAU for clinical efficacy is highly recommended.
