Increased burden of booster shots for COVID-19 amidst vaccine hesitancy in Pakistan.

Pakistan is dealing with the fifth wave brought on by the new type, Omicron (or B.1.1.529) with 1,547,795 confirmed cases with 30,452 deaths of COVID-19, as reported by World Health Organization (WHO) from 2020 to 2022. Vaccination is the best tool to curb this pandemic and fight against the new variants as it reduces the likelihood that the disease will be severe. A two-dose regimen of the BNT162b2 vaccine provides 95% protection to people aged 16 years and above, against the novel coronavirus. However, like in other developing countries, the vaccination campaign in Pakistan is hampered due to vaccine hesitation. This might not be the last mutation the world shall face. As with any other virus, the corona-virus is also expected to mutate frequently in the future, making annual booster shots the only way to stay significantly immunized against this deadly virus. Communication and counseling are needed to build their trust while taking care of social inequalities in the population. The authorities must intensify their efforts and should address this very important issue.
