Do post-COVID 19 patients need a second dose of the vaccine?
The Richmond Research Institute compared the level of antibody response to COVID vaccines between those who have and have not previously been infected by the virus to establish their degree of immunity. Background on the safety measures in place: Testing for COVID-19 is crucial to understand who is infected and therefore a risk to others by spreading the infection. By repeating these tests over time, we can establish how long the antibodies take to develop and how long immunity may last in each person. Routine testing of staff, trial volunteers, and visitors began on 19 March 2020. The rigorous testing procedure consists of multiple tests to ensure the results are reliable. This minimizes the risk to all entering the unit. All staff have been offered a COVID-19 vaccine.
