Health director-general Tan Sri Dr Noor Hisham Abdullah recommends that people who have recovered from Covid-19 should be vaccinated after three months of recovery to prevent reinfection. Although the recovered patients will have antibodies in their bodies, it is still unclear how strong this immune response is and how long it can last.
Coronavirus patients have a low risk of being re-infected by the same virus shortly after recovery. Studies in the United States, the United Kingdom, and Denmark have shown that 80 to 90% of patients will not be re-infected with coronary disease within about 6 to 8 months.
According to a report from the online media “Perspective Malaysia”, Tan Sri Dr Noor Hisham Abdullah pointed out that people who have recovered from coronary disease still need to be vaccinated to obtain protection through high humoral or cellular immunity.
The World Health Organization (WHO) has stated that people who have recovered from Covid-19 will have an immune response in the first few weeks after recovery, but it is not clear how strong and how durable this immune response is. The immune response may vary from person to person, and there are cases of reinfection, so vaccination is important to prevent reinfection issues.
