Yes, even if you’ve already been infected, you should still get vaccinated once you have recovered. It is recommended that you get one dose of your vaccination approx. four weeks after your infection (amended by National Vaccination Board dated 5 July 2021).
It can be assumed in such a chase that your existing immunity will be boostered with the vaccine and your protection thus prolonged. Aside from the medical/immunological assessment, two vaccines may be required for international travel and when entering another country. In such cases, a second dose may be administered for formal reasons. When receiving a second dose, an increased rate of vaccine reaction in persons who have recovered from an infection cannot be ruled out.
