evidence: NEW As of 10th January 2022, Health Care Workers and Front-Line Workers who have received two doses of the COVID-19 vaccine are eligible to receive another dose of the vaccine called the precaution dose. All persons aged 60 years and above with comorbidities and who have received two doses of the COVID-19 vaccine are eligible to receive the precaution dose based on their doctor’s advice. The order in which these precaution doses would be given are based on the completion of 9 months or 39 weeks from the second dose. [...] Once a person gets COVID-19, their body starts producing antibodies to it. Therefore, experts suggest waiting 3 months after recovering from COVID-19 before getting the second dose. Getting the second dose is important to ensure an effective immune response against COVID-19 in the future. [...] - It’s possible a person could have been infected just before or just after vaccination. It typically takes about 2 weeks for the body to build protection after the second dose of vaccination. Thus, a person can get sick if the vaccine has not had enough time to provide protection.
